Hey gang,
I recently found a small computer in a junkyard and was wondering if anyone
can help to identify it. All I got was the backplane and a handful of cards.
No disks, no cabinent, no power supply, and no markings on any of the cards.
The cards are approximately 4" x 5" and have a 56 pin edge connector with
.156" spacing. At first I thought it might be STD bus but, STD uses .125"
spacing so, that's not correct. Also the cards are smaller than STD and are
mounted "sideways" (long side has the edge connector).
The CPU card has a RCA 1802ACE processor, a 2M crystal oscillator, and some
glue. There are a couple of I/O cards, identifiable by the existance of
optoisolators on the cards. There's a ROM card populated with 8 x 2764's.
Not sure but, that seems like a *lot* of ROM for this system. There's also a
RAM card with a minimal amount of RAM and another card with a MC14034B
keyboard encoder.
I don't have any other 1802 stuff and would like to see if I could get it to
do anything. If anyone has any ideas as to what this might be, I'd
appreciate some info.
