Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

TRS-80 Model 100 Portable Computer

The TRS-80 Model 100 portable computer was introduced in 1983. It was made by Kyocera, and originally sold in Japan as the Kyotronic 85. Although a slow seller for Kyocera, the rights to the machine were purchased by Tandy Corporation, and the computer was sold through Radio Shack stores in the United States and Canada as well as affiliated dealers in other countries, becoming one of the company's most popular models, with over 6,000,000 units sold worldwide. The Olivetti M-10 and the NEC PC-8201 and PC-8300 were also built on the same Kyocera platform, with some design and hardware differences.

The TRS-80 Model 100 was one of the first-ever notebook computers. It was originally marketed as a Micro Executive Work Station (MEWS), although the term did not catch on and was eventually dropped.

Processor: Eight-bit Intel 80C85, CMOS, 2.4 MHz
Memory: 32K ROM, 8, 16, 24, or 32K static RAM. Machines with less than 32K could be expanded in 8K increments of plug-in static RAM modules.
Display: Eight lines, forty characters LCD with 240 by 64 pixel addressable graphics. The screen was not backlit.
Peripherals: The basic package included: Built-in 300 baud modem (North American versions), parallel printer port, serial communication port (shared by internal modem), bar-code reader input, cassette audio tape, real-time clock.
Dimensions: 300 by 215 mm by 50 mm, mass about 1.4 kilograms (3.1 lb) with batteries
Power supply: Four penlight (AA) cells, or external power adapter 6V (>180 mA, tip negative configuration)

The 8K and 24K versions sold for USD$1099 and USD$1399 respectively.

It 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.

The keyboard has 56 keys, eight programmable function keys, and four dedicated command keys, but neither a backslash () nor a pipe (|) key.

Our model has a serial number of 305100832 and was kindly donated by Mike & Jenny Davies and is complete with a soft case and is in excellent condition. It is complete with the following manuals:
