thanks for all the comments on the device! no idea yet what it is but
most thoughts center around something phone related. FWIW, I've added
some more photos (better focus - chip IDs are more clear) to the album
(large/hi-res) for anyone interested.
In response to a couple specific questions, the 3 40pin dips are indeed
6522PIAs. The 3 chips with "labels" are 2732 EPROMS and the "labels"
are actually some form of paint rather than a paper label. The
printer paper is loaded in a small "well" in the back of the case and
fed up through a slot to the ptr mechanism, allowing paper loading to be
accomplished without opening the case. There also appears to be some
form of I/O terminating in a 16pin header that is available as a ribbon
connector at the rear of the unit.
on to 6502.org to see what that group can offer....

Thus it has no provenance of any kind. There appears to be no
information on the web searching the usual places and using the obvious
terms.
Unit is labeled "Mark 1". It has a 6502 CPU and the appropriate support
chips to qualify as a SBC although the keypad is not labeles as a
typical hex pad. Date codes seem to be early 80s. The printer uses a
character belt rather than thermal.
only label anywhere on the unit seems to be the two "Made in Hong Kong"
stickers!
thoughts/suggestions on what this is or where to look for more info
would be most welcome! (plan to post a msg on 6502.org but figured to
start here)
