+      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+      ASCI''s marketing catchphrase for the System X was "a system so updated, it can''t be outdated".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. :)

+
+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.
