Historia

The MEK6800D2 was a development board for the Motorola 6800 microprocessor, produced by Motorola in 1976. It featured a keyboard with hexadecimal keys and an LED display, but also featured an RS-232 asynchronous serial interface for a Teletype or other terminal. Data and programs could be loaded from and saved to an audio cassette tape. There was an on-board monitor program called JBUG (analogous to an operating system on a modern computer) fitted in a 1K byte ROM, and the maximum RAM capacity on board was 512 bytes, but this could be expanded via the Motorola EXORciser computer bus interface.

Historia

The PRO-80 by Protec of Montreal, Quebec Canada is described as an S-100 Trainer. Essentially a single-board Z80 computer, this unit features a single S-100 expansion slot. The system incorporates 1K or ROM, 1K or RAM (expandable on-board to 2K), and a keypad/display. The idea was to provide a very low cost means of experiementing with S-100 cards, albeit one card at a time.
