Commodore, established in 1954 by Jack Tramiel, initially focused on office furniture and typewriters before transitioning into the electronics industry. The company gained significant traction in the 1970s with the release of the Commodore PET (Personal Electronic Transactor), one of the earliest personal computers available to the general public. Commodore continued its success with the VIC-20 and the iconic Commodore 64, which became the best-selling personal computer model of all time. However, internal struggles and market changes led to financial difficulties in the late 1980s, resulting in the company's bankruptcy in 1994. Despite its eventual downfall, Commodore left an enduring legacy in the world of personal computing, shaping the industry with its innovative products and democratizing access to technology for millions around the globe.

Commodore VC20My favorite Commodore machine! To be completely honest, I must admit that I’m not yet very well acquainted with the VIC-20, or its German counterpart, the VC-20.
Interestingly, the German variant was renamed VC-20 to avoid unintended connotations. When pronounced with a German accent, “VIC” can sound similar to certain German expletives, which made the name less than ideal for marketing a home computer. Despite my current unfamiliarity with the platform, I’m genuinely excited about exploring the VIC/VC-20 in more depth. One of my goals is to become better acquainted with the system while restoring this particular machine as part of an episode of Computer TLC. If you are interested in that restoration process, you can find the episode under the “Appearances” tab on this page. Why the VIC 20 Matters:The VIC-20 (known as the VC-20 in Germany and VIC-1001 in Japan) was introduced by Commodore in 1980, roughly three years after the Commodore PET.
The machine holds an important place in computing history as the first computer to sell more than one million units. At a time when most computers were still expensive and aimed at businesses or hobbyists, the VIC-20 helped bring personal computing into ordinary homes. |

Commodore 16
Part of Commodore’s short-lived but fascinating TED computer family. The story of how this Commodore 16 entered my collection is quite simple: it was offered at a good price.
I came across it while browsing the Dutch version of eBay and quickly decided to add it to the collection. My familiarity with the Commodore 16 platform is therefore still fairly limited, but that also makes it an interesting system to explore. One of my goals with this machine is to become more familiar with the platform and eventually begin archiving the cassette tapes in my collection, and adding them to my Archive site. Why the commodore 16 mattersThe Commodore 16, introduced in 1984, was part of Commodore’s TED-based family of home computers, which also included the Commodore Plus/4. These machines were designed as successors to earlier systems like the VIC-20, offering improved graphics, sound capabilities, and a more modern architecture.
Although the Commodore 16 never achieved the widespread popularity of the Commodore 64, it represents an interesting moment in Commodore’s history. The machine was intended as an affordable entry-level computer aimed at home users and beginners, particularly in Europe. |

Commodore 128D
Commodore’s 8-bit line in a far more substantial desktop form, and I Love it! Oops, I got a Commodore 128D.
I came across this one on the Dutch version of eBay with an asking price that was high, but still reasonable. Usually sellers prefer to let buyers bid, and I had seen before that this type of machine can fetch serious money. Still, I found the design of the computer very appealing, especially its bulky desktop form factor with the built-in disk drive. So I contacted the seller and asked whether he would be willing to sell it for the asking price, including shipping. He agreed, I transferred the money, and the Commodore 128D was soon on its way to me. You could say this was quite an unexpected purchase — but one I am very happy with. I really like that I now have a Commodore 64-compatible machine in a desktop form factor, complete with an integrated disk drive. At the same time, the Commodore 128 is more than just a differently shaped C64, and I definitely want to cover that in a future video, showing both the differences and the aspects I particularly like about it. Interestingly, this Commodore 128D came from the same seller as my TRS-80 Color Computer 2. I also own a standard Commodore 128, which makes this machine an especially interesting addition to the collection. |

Why the Commodore 128D matters
The Commodore 128D represents Commodore’s effort to build a more capable and more refined successor to the hugely successful Commodore 64. Introduced in the mid-1980s, the Commodore 128 line combined backward compatibility with the C64 with expanded memory, additional operating modes, and a stronger focus on productivity.
What makes the 128D especially interesting is its desktop form factor and built-in disk drive, giving it a more substantial and professional appearance than the standard Commodore 128. It reflects a moment in home computing when manufacturers were trying to bridge the gap between home computers and more serious personal computer systems.
Although the Commodore 128 never surpassed the popularity of the C64, it remains historically important as one of Commodore’s most ambitious 8-bit machines. For collectors, it is a fascinating example of how Commodore tried to extend the life of the 8-bit platform while offering users something more powerful and versatile.

Commodore 128
The design of the Commodore 128 is just incredible! This was my first Commodore 128, and a very nice one at that. I picked it up only about five kilometers from my house, which made it a particularly easy and satisfying addition to the collection.
Cosmetically, the machine could probably benefit from some retrobrighting, although I am still a little hesitant to do that. One especially nice aspect of this example is that it came with its original packaging, something that always adds to the appeal of a vintage computer. It also came with a very nice Commodore 1571 disk drive, as well as a copy of The Last V8, a rare game specifically optimized for the Commodore 128 rather than being just another Commodore 64 title. Altogether, this makes it a particularly enjoyable example of the Commodore 128, and a very welcome machine in the collection. |

Why the Commodore 128 matters
The Commodore 128, introduced in 1985, was Commodore’s attempt to build a more advanced successor to the enormously successful Commodore 64 while remaining compatible with the earlier machine.
What makes the Commodore 128 historically important is that it reflects a transitional moment in home computing. Manufacturers were trying to offer users more memory, more capable operating environments, and better productivity features, while still preserving access to the large software libraries that had made earlier systems popular. The Commodore 128 did exactly that by combining C64 compatibility with expanded memory, improved BASIC, and additional operating modes including CP/M.
Although it never displaced the Commodore 64 in popularity, the Commodore 128 remains one of Commodore’s most ambitious 8-bit systems. It stands as an example of how the company tried to extend the life of the 8-bit home computer while also pushing the platform toward something more versatile and powerful.

Commodore PET 2001
IMO: The Commodore PET resembles Retro Futurism at it's best! This was one of those computers that I simply had to have in my collection. To add it, I did have to pay a bit more than usual, but I have never regretted that decision. Every time I walk past it in the hallway I feel happy that I went ahead and bought it.
The Commodore PET is such an aesthetically striking machine and a genuine piece of computer history. Its distinctive integrated design, with the monitor, keyboard, and cassette drive built into one unit, makes it immediately recognizable. Although the PET is not necessarily the best machine for someone who primarily wants to play games, it represents an important early step in the development of personal computers. This particular PET has appeared in multiple videos. One shows the pickup of the machine, and another is a crossover episode between Adventures in Archiving and Computer TLC, where I archive cassette tapes from the system but unfortunately fail to repair the keyboard. |

Why the Commodore PET matters
The Commodore PET, introduced in 1977, was one of the first widely available personal computers and is often grouped together with the Apple II and TRS-80 as part of the early “1977 Trinity” of home computing.
Unlike many earlier computers that were sold as kits or required significant technical knowledge, the PET was designed as a complete, ready-to-use system. With its built-in monitor, keyboard, and on some units cassette drive, it offered users a self-contained computer that could be used immediately after purchase.
The PET quickly found its way into schools, laboratories, and businesses, where it was used for education, programming, and early office tasks. Its robust all-in-one design made it particularly suitable for institutional environments.
Today the PET is remembered not only as one of Commodore’s earliest personal computers but also as a machine that helped establish the concept of the personal computer as a practical, accessible tool.

remember the days when I was actively looking for a Commodore 64 to add to my collection. These days the situation is quite different — I now have around eight complete systems and roughly thirty C64 motherboards.
The Commodore 64 is a computer I continue to enjoy collecting and working with. One of the main reasons is its enormous software library, ranging from games and demos to programming tools and utilities. At the same time, the platform remains very much alive today thanks to the retro computing community. Many enthusiasts are still designing new price friendly peripherals, expansions, and storage solutions for the C64, which makes it a fascinating system to explore both from a historical perspective and as an actively used retro computer platform. Why the Commodore 64 matters (a lot)The Commodore 64, introduced in 1982, is widely regarded as one of the most important home computers ever produced. With millions of units sold worldwide, it became the best-selling single computer model in history and played a major role in bringing computing into homes during the 1980s.

Commodore PC10-III
A lovely MS-DOS PC This lovely Commodore PC10-III came into my collection via the Dutch version of eBay. It is the first PC-compatible Commodore computer in my collection, which makes it a particularly interesting addition.
Although Commodore is best known for machines like the Commodore 64 and the Amiga, the company also produced a number of IBM PC compatible systems during the 1980s. The PC10-III is a good example of that lesser-known side of Commodore’s history. This particular machine is in working condition and currently requires no repairs. I have installed an XT-CF adapter, which allows the system to use a CompactFlash card as storage. This makes the computer much easier to use while still keeping the experience close to the original system. |

Why the Commodore PC10-III matters
The Commodore PC10 series represents Commodore’s entry into the rapidly growing IBM PC compatible market of the mid-1980s. As IBM-compatible computers became the dominant platform for business and productivity software, many manufacturers began producing their own compatible systems.
Commodore’s PC line shows how the company tried to participate in this expanding market alongside its more famous home computer platforms. While machines like the Commodore 64 and Amiga targeted home users and creative applications, the PC series was aimed at the growing demand for business and professional computing based on MS-DOS.
Today systems like the PC10-III provide an interesting perspective on Commodore’s broader history. They illustrate how the company explored multiple directions in the computer industry during the 1980s, including the emerging PC-compatible ecosystem that would eventually dominate personal computing.

Commodore VIC 20 With Eurostile style keys
I thought PET but turned out to be Eurostile This is my second VIC-20. I bought it because I wanted one with the VIC-20 badge, as my first machine was actually a VC-20, the German version of the system. Of course there is no real difference between the two when it comes to the computer itself, but I still thought it would be nice to also have a VIC-branded version in the collection.
When I received this machine I discovered something interesting: it is one of the VIC-20 models that still features the PET-style keyboard, which makes it a bit more special. Just like my VC-20, this computer will need some restoration work and probably a retrobright treatment. At some point someone also used something hot to melt letters into the case, which is a bit unfortunate. My current plan is to carefully file those markings away. I really enjoyed restoring the VC-20, as these machines are very compact and nicely designed, so I will most likely try to tackle this one soon as well. |

Amiga 500
This machine is my introduction into the platform As becomes clear from this page, I’m not yet very familiar with the Amiga platform. Because of that, I decided to look for a machine that needed a fair amount of tender loving care (TLC) so it could serve as a good entry point into the system.
As you can see in the picture, this particular Amiga 500 is heavily yellowed and has some minor case damage. I will also need to 3D print a replacement side door for the expansion port. The computer came with an expansion installed, although I’m not yet sure what type of expansion it is. That is something I will need to investigate further, most likely as part of the upcoming Computer TLC episode. Another thing that came with the computer was a large number of 3.5-inch disks. That’s one of the things I really appreciate about the Amiga platform — there is still a lot of physical software media around, unlike platforms such as the Apple II or TRS-80 where original media can sometimes be harder to find. I’m looking forward to exploring the Amiga ecosystem and seeing whether I enjoy it as much as the other Commodore machines in my collection. |

Why the Amiga 500 matters
The Amiga 500, introduced in 1987, was Commodore’s effort to bring the advanced multimedia capabilities of the Amiga platform into a more affordable and accessible home computer.
Building on the earlier Amiga 1000, the Amiga 500 combined powerful graphics, digital stereo sound, and true multitasking into a compact keyboard-style computer. At a time when many home computers still relied on simple graphics and limited sound capabilities, the Amiga platform offered features that were far ahead of most competitors.
The Amiga 500 quickly became one of the most popular Amiga models, especially in Europe, where it was widely used for games, creative software, and the emerging demo scene. Its custom chipset and strong multimedia capabilities made it particularly attractive to developers and enthusiasts.
Today the Amiga 500 remains an iconic system in computing history and continues to enjoy an active community of users, collectors, and developers who keep the platform alive through new software, hardware expansions, and preservation projects.

Commodore 202
one beefy calculator This Commodore 202 calculator is the oldest piece of Commodore equipment in my collection. Compared to the home computers Commodore later became famous for, it is a very different kind of machine.
It is a surprisingly bulky little calculator, but at the same time it looks fantastic. The design immediately reflects the era in which it was produced, when electronic calculators were still relatively new devices. What makes this particular example even nicer is that it still works, which is always a pleasant surprise for hardware of this age. |

Why the 202 matters
Before Commodore became famous for home computers like the Commodore PET, VIC-20, and Commodore 64, the company was heavily involved in the electronic calculator market during the late 1960s and early 1970s.
In fact, Commodore originally started as a manufacturer of typewriters and office machines, and calculators became an important part of its business as electronic components began replacing mechanical calculating devices. During this period the company produced a wide range of desktop calculators aimed at businesses, offices, and technical users.
Machines like the Commodore 202 represent this earlier phase of the company’s history. They show the transition from traditional office equipment toward electronic devices based on integrated circuits.
This shift would eventually lead Commodore into the computer industry. When the calculator market became extremely competitive in the mid-1970s, Commodore began developing its own computers, culminating in the release of the Commodore PET in 1977.
Seen from this perspective, early devices like the Commodore 202 form an important part of the company’s story, illustrating how Commodore evolved from an office equipment manufacturer into one of the most influential computer companies of the late twentieth century.
In fact, Commodore originally started as a manufacturer of typewriters and office machines, and calculators became an important part of its business as electronic components began replacing mechanical calculating devices. During this period the company produced a wide range of desktop calculators aimed at businesses, offices, and technical users.

Commodore C386SX-LT
A laptop from Commodore This Commodore C386SX-LT is the more powerful version of a Commodore laptop released around 1990, designed to be compatible with the IBM PC standard.
I obtained this laptop quite some time ago, when I first started collecting vintage computer hardware. At the time I was interested in exploring Commodore’s lesser-known systems beyond the more famous home computers such as the Commodore 64 and the Amiga. Unfortunately, I have not yet been able to get this particular machine functioning properly. I performed some tests a few years ago, which led me to suspect that the display component may be defective. At some point I hope to take another look at it and see if the issue can be resolved. Even though it currently does not work, it remains an interesting part of the collection because it represents a different chapter of Commodore’s history. |

Why the C386SX-LT matters
By the late 1980s and early 1990s, the IBM PC compatible architecture had become the dominant platform in the personal computer industry. Many manufacturers began producing their own PC-compatible machines in order to participate in this rapidly expanding market.
Commodore, best known for systems like the Commodore 64 and the Amiga, also produced a range of IBM PC compatible computers and laptops during this period. Machines such as the C386SX-LT demonstrate how the company attempted to compete in the growing business and professional computing market.
These systems represent an interesting and sometimes overlooked part of Commodore’s history. While they never achieved the same recognition as the company’s home computers, they illustrate Commodore’s broader strategy during a time when the computer industry was rapidly consolidating around the PC standard.
Today laptops like the C386SX-LT provide a glimpse into the early era of portable DOS computing, when manufacturers were experimenting with bringing desktop PC performance into increasingly compact portable machines.

Commodore GL-997R
Love the low serial number on this one! A nice little calculator from Commodore. At the moment I am not yet sure whether it works, as I still need to source a suitable power supply before I can test it properly.
The most interesting thing about this particular example is its serial number: 00034. Based on the examples I could find during research, that appears to be an unusually early number. For comparison, the Smithsonian’s documented GL-997R has serial number 73954, while collector references list other examples with serials such as 28319, 034231, 05181, 14951, 25166, 44655, and 56045. That does not prove mine is one of the very first units made, but it strongly suggests it is an early example of the model. Why the GL-997R mattersThe Commodore GL-997R belongs to an earlier phase of Commodore’s history, before the company became best known for home computers like the PET, VIC-20, Commodore 64, and Amiga. In the early to mid-1970s, Commodore was heavily active in the calculator market, and handheld electronic calculators like this one formed part of that business.

Calculator Overview
|
This particular model is interesting because it sits in Commodore’s “Custom Green Line” range and is described by calculator collectors as an improved follow-up to the GL-987R, mainly through its larger display. It also includes memory functions and an EX key, which gives it a bit more character than a very basic four-function calculator.
For a Commodore collection, machines like this matter because they show the company’s path before personal computers. Commodore’s calculator business was one of the stepping stones that eventually led to its later computer products. In that sense, the GL-997R is not just a calculator, but part of the broader pre-history of Commodore as a computing brand.

Commodore 9R-25 Calculator
A small handheld calculator from Commodore’s pre-PET era. A small but interesting handheld calculator from Commodore. Unlike some of the other calculators in my collection, this one has already been tested and confirmed to be working.
The Commodore 9R-25 belongs to the period when Commodore was still heavily involved in the electronic calculator market, before the company became famous for its home computers. Machines like this were part of Commodore’s effort to compete in the rapidly expanding calculator market of the early 1970s. While these devices are much simpler than later Commodore computers, they represent an important stage in the company’s technological development. Why the 9R-25 mattersBefore entering the personal computer market, Commodore produced a wide range of electronic calculators, both desktop models and portable handheld devices. During the early 1970s the calculator market grew rapidly as integrated circuits made electronic calculation more affordable.
The 9R-series calculators, including the 9R-25, belong to this phase of Commodore’s history. These machines demonstrate how the company was transitioning from mechanical office equipment toward electronic devices. |

Commodore 1701
One of the prettiest CRT's in my collection! The Commodore 1701 monitor is one of those pieces of hardware that immediately evokes the design language of the Commodore 64 era. The beige case, the horizontal ventilation slots, and the subtle lines of the front panel fit perfectly alongside a C64 or Commodore 128.
For many people the Commodore 64 is remembered primarily as a computer, but the experience of using one was very often tied to the dedicated Commodore monitors that accompanied it. The 1701 belongs to that family of displays designed specifically to complement Commodore’s home computers. With its clean and unmistakably 1980s Commodore aesthetic, the 1701 remains a very attractive monitor to pair with machines like the C64 or VIC-20. Why the 1701 mattersThe Commodore 1701 was introduced in the early 1980s as a monitor designed to work well with Commodore’s home computer systems, especially the Commodore 64. Unlike many televisions used with early home computers, the 1701 supported separate video inputs, allowing users to obtain a much sharper image than RF television connections typically provided.

Monitor Overview
|
This made the monitor particularly useful for programming, productivity software, and games where clear text and graphics were important.
One practical thing collectors quickly learn about the 1701 is that the front control panel can be quite fragile. The plastic panel that holds the brightness and contrast controls is known to crack or break if handled roughly. Because of that, surviving examples with an intact front panel are always a bit nicer to find.
Today the 1701 remains a popular display among retro computing enthusiasts because it provides an authentic viewing experience for Commodore computers, with image quality that is often noticeably better than using a period television.

Commodore Plus/4
A Commodore with 64K but called Plus/4? It had been a while since I added a new type of Commodore computer to my collection. Of course, during that time I did acquire a few additional Commodore 64s and VIC-20s, but I had not yet expanded the collection with another distinct model.
This Commodore Plus/4 came to me via the Dutch version of eBay. It appears to be working, but the keyboard clearly needs some attention. Although it is possible to type on the machine, the keys require a considerable amount of force before they register. Because of that, restoring or servicing the keyboard will likely be one of the first things I look into when I spend more time with this machine. Even with that issue, it is nice to finally add a Plus/4 to the collection, as it represents another interesting branch in Commodore’s family of home computers. Why the Plus/4 mattersThe Commodore Plus/4, introduced in 1984, was part of Commodore’s attempt to create a new generation of home computers intended to replace or complement the earlier VIC-20 and Commodore 64.

System Overview
|
The system belonged to what is often called the TED computer family, which also included the Commodore 16 and Commodore 116. These machines featured a new custom chip (the TED) that combined graphics, sound, and memory management functions.
Unlike the Commodore 64, the Plus/4 was marketed more toward productivity and small business use rather than primarily gaming. The system even included a suite of built-in applications in ROM, such as a word processor, spreadsheet, database, and graphing program — something that was quite unusual for home computers at the time.
Despite these ambitions, the Plus/4 faced difficulties because it was not compatible with the enormous software library of the Commodore 64, which limited its adoption.
Today the Plus/4 is remembered as an interesting and somewhat unusual part of Commodore’s history — a system that attempted to move the company’s home computers toward a more productivity-oriented direction, even though the C64 ultimately remained the dominant platform.
