I've been searching the net for more info on this card. The only thing
that I can find is a mention of one in the Smithsonian.
<http://smithsonianchips.si.edu/texas/t_344-2.htm> It's severly damaged and
is a year newer than mine. Very cool find! I'll try to get it cleaned up
and photographed and post some pictures later this weekend.
In addition to a TI TMS9916NL LSIC, it has six large

may be bubble memories. They're about 1
