I recently found a TR model 100 with an odd looking device plugged into
it. Abouty half of the access door on the bach is cut away in it and there
is a 20 pin ribbon cable header inside the cut out. Stamped in the header
is "H&T 20". I don't know if that's the name of just the head4er or
the
entire assemble. I removed the cover plate and inside is a small PC card
with the header and three SSI ICs (74HC245, 74HC02 amd a 74HC244). The
whole thing fits inside the original opening (so you don't have to remove
the back case to install or remove it) and it plugs into the 28 pin LSI IC
socket. Does anyone know what this is?
Hint: It will ber looking fore a home at this weekend's computer junkfest
in Orlando.
