ASCI
SystemX

The ASCI SystemX, also called U68 was a single board training system that was used in an educational environment during the early 1980s.

It was mounted in a wooden box and covered with a smoke colored plastic lid. When it was closed, all the electronic part was covered, except the 16 key hexadecimal keypad and a seven digit LED display.

The main board featured a Motorola 6800 processor and an Exorciser bus connector. Several I/O boards could be connected to the system allowing microprocessor based experiments.

Motorola 6800 is a 8-bit microprocessor which was released at about the same time as Intel 8080. The 6800 had 16-bit address bus and could address up to 64 KB of memory. From common registers the CPU had only two accumulators and one index register. The 6800 didn't have I/O instructions and therefore 6800-based systems had to use memory-mapped I/O for input/output capabilities. Motorola 6800 started the big family of 680x microcontrolers and microprocessors, some of which are still produced today.

Was lucky enough to find four of these that were being thrown out by a school.

The ASCI System X also had an RS-232 port and an available expansion board with BASIC on ROM. IIRC BASIC was launched from the monitor by:

G
F836
D

The BASIC board could eat itself if a user POKEd at the wrong addresses.

ASCI''s marketing catchphrase for the System X was "a system so updated, it can''t be outdated". I''m not gonna hold my breath waiting for a USB 3.0 interface though. :)
