Believe it or not but I added the wonderful Tandy TRS-80 model 100 to my collection a couple of years ago for free. I got it from the original owner that understandably felt a bit hesitant to let go off it. He also gave me a tape recorder, a floppy drive with floppies and a printer that needs it's belts replaced.
Currently it has some issues with the display and needs some retrobright This will probably be tackled in a future computer TLC Specs:

- Display: 8 lines, 40 characters LCD, twisted nematic (gray) monochrome, with 240 by 64 pixel addressable graphics. The screen is reflective, not backlit. The screen was made by Sharp Electronics.The LCD controllers are by Hitachi: (10) HD44102CH column controller ICs and (2) HD44103CH row driver ICs; the HD44102CH's provide the programmable hardware interface to software. The refresh rate is about 70 Hz(coarsely regulated by an R-C oscillator, not a crystal).
- Keyboard: 56 keys, QWERTY layout with full standard spacing, 8 programmable function keys, 4 dedicated command keys. These last 12 are tactile "button"-style keys. Almost all keys other than the 12 function keys are capable of rollover (without phantom keys appearing depressed), so multi-key combinations can be used.
- Peripherals: The basic unit includes: Built-in 300 baud telephone (POTS) modem (North American versions), Centronics-compatible parallel printer port, RS-232 serial communication port (sharing serial I/O chip with internal modem), barcode reader input, cassette audio tape I/O, real-time clock.
- Expansion: System bus interface DIP socket (under a cover on the bottom of the machine).
- Dimensions: 300 by 215 mm × 50 mm, weight about 1.4 kilograms (3.1 lb) with batteries
The 8K and 24K versions sold for US$1,099 and US$1,399 respectively.
The Model 100 was promoted as being able to run up to 20 hours and maintain memory up to 30 days on a set of four alkaline AA batteries. It could not run from the rechargeable nickel-cadmium batteries available at the time, but a hardware modification was available that made this possible.

This like the model 100 I managed to find for a lovely price, well I guess if your a collector that you find most prices nice but for 25 bucks I want to call this working model 200 a steal. Like the 100 it is powered by 4 double AA's.
The Tandy 200 was introduced in 1984 as a more capable sister product of the Model 100. The Tandy 200 has a flip-up 16 line by 40 column display and came with 24 KB RAM which can be expanded to 72 KB (3 banks of 24 KB). Rather than the "button" style keys of the Model 100, its four arrow keys are a cluster of keys of the same size and shape as those comprising the keyboard, though the function and command "keys" are still of the button type. The Tandy 200 includes Multiplan, a spreadsheet application. It also added DTMF tone dialing for the internal modem, whereas the Model 100 only supports pulse dialing. On a phone line that doesn't support pulse dialing, users may dial manually using a touch-tone phone and then put the Model 100 online.

initially called just the TRS-80 Pocket computer it was quickly rebranded as the TRS-80 Pocket Computer PC-1. It is an rebadged Sharp PC 1211 which I also have In my collection.

The PC-2 is funnily also almost twice as thick as the PC-1.

This is me mainly trying out my ZV-1 in a badly lit room

Where the PC-2 was double the thickness of the PC-1. The PC-3 is the smallest of the bunch being very thin and small.

After seeing this computer at the Home Computer Museum in Helmond, I knew I had to have it. So, when I found it on eBay, I made the purchase. It was shipped all the way from the United States, making it the first computer from the USA in my collection. However, connecting it to a television using NTSC RF proved to be a bit trickier.
The computer has already appeared in a couple of videos, which you can find under the Appearances tab. |

This computer I bought when it popped up on my daily search for vintage computers on the dutch version of Ebay. It is a lovely machine and because my eternal lack of space a machine. I appreciate for it's small form factor. It needs some retrobright and an overall good clean that I will save for a Computer TLC.
Specs: The Tandy 1000 EX and HX were designed as entry-level IBM-compatible personal computers, and marketed as starter systems for people new to computing. They were offered in a compact, all-in-one chassis that featured a 7.16 MHz 8088 (capable of clocking down to 4.77 MHz), |

256 KB of memory (expandable to 640 KB with a PLUS memory expansion board), PCjr- and CGA-compatible Tandy Video graphics controller, a keyboard and, depending on the model, either a single 5.25" 360 KB floppy drive, or one to two 3.5" 720 KB floppy drives. An external floppy drive could be connected to a port on the back. The machine itself supplied power to the external drive, so only Tandy's floppy drive unit was usable with the EX and HX. The external drive was the standard 360 KB 5.25 inch format; in 1988 a compatible 720 KB 3.5 inch model was offered.
The EX and HX are upgradable via Tandy PLUS cards, and these systems have bays for three cards. A PLUS card connector is electrically identical to an ISA slot connector, but uses a Berg-style 62-pin connector instead of a 62-contact ISA card-edge connector. Other PLUS cards could be installed to add serial ports, a 1200-baud modem, a clock/calendar and bus mouse board, or a proprietary Tandy network interface. Radio Shack later sold an adapter card allowing installation of a PLUS card into a standard ISA slot, such as those in the larger Tandy 1000 models.
Like the original Tandy 1000, the EX and HX do not have a built-in DMA controller, though one can be added using the PLUS memory expansion board.

The Tandy 1000 EX featured a 5.25" floppy drive built into the right-hand side of computer casing. The EX sold for US$1,000 from Radio Shack in December 1986. The EX and, later, the HX would be among the most popular of the Tandy 1000 line because of their (relatively) low price.
A useful feature for the EX and later systems was the ability to boot off either drive, as the drives could be logically swapped when the system booted, so that the drive that was normally drive B: became drive A:, and vice versa, and the drives remained swapped until the system was powered off or reset. (The SX and TX have this capability as well.) The 1000 EX came with MS-DOS 2.11 and Personal Deskmate on 5.25" 360kB diskettes. The MS-DOS was a version specialized for and only bootable on the Tandy 1000; it included a version of BASICA (Microsoft's Advanced GW-BASIC) with support for the enhanced CGA graphics modes (a.k.a. Tandy Graphics or TGA) and three-voice sound hardware of the Tandy 1000. |

I finally found one! and for a nice price. While visiting the Home Computer Museum in Helmond I set as a goal for 2023 to add a Colour Computer to my collection, so here it is.
This is computer came from the same home as my Commodore 128D More info to come! |

I love the look of the silver painted case on this computer. At first I expected the keyboard to be difficult to use, but it turns out to be pretty decent.
I have really come to love this line of computers, as they are fun and easy to use. I am really thinking about getting a SD card solution for this range. But they are a bit expensive. |

I purchased this computer after stumbling upon it in the inventory of a closed-down pharmacy. I sent the seller an email, inquiring if they were willing to sell it separately from the surplus of landline phones, to which they fortunately agreed. Although the badge on the machine reads "NPC 8000 Computer System II," it is actually a Radio Shack TRS-80 Model III.

The TRS-80 Model III or as the badge implies the NPC 8000 Computer systeem II did not YET (emphasis on the yet) make an appearance on the channel. Since it has an blown RiFa cap that needs to be taken out it probably won't be long.
