ASCI micro68 system

[Carlos Murillo]

I think that I've asked about this system before. It seems
to be a 6800 training system with hex keypad and 4 digit display,
rs-232 and perhaps a cassette interface.  It is labeled
"ASCI u68" (the "u" is a greek mu) and "SYSYEM X".
Apparently, it might have been known also as "micro mule II",
according to a vey old sale ad that I found. It is nicely
built on a black metallic chassis with wooden sides and a
flip-over acrylic top.

The serial interface seems to adjust to the terminal's baud
but insists on using 7bit, odd parity.  I've been able to
examine and change the memory's contents using the hex keypad.

There's a flap for a card edge connector that remains free;
I guess it is probably for the cassette (I haven't yet traced
the thing).

Unfortunately, my web searches have yielded lots of info about
ASCI supercomputers, misspellings of ASCII and in one
occasion  a misspelling of micromole by some chemist,
but nothing useful about this system. There seems to be one in 
the Topeka Computing Museum collection

So, does anybody have info about this system?

Carlos.
