Hope to generate less heat this time.
Full length ISA card, XT card edge connection, DB 37
male connector,
Z80B, 8 4164's, 2 2764's, 2 Mostek MK4801AN-4's, MC1420B, 10 MHZ
crystal, and a handful of 74LSxxx glue chips. Only identification
lettering is "BETRONIX = SWEDEN=PC84"
Well, what do we have:
Z80
64K RAM
16K ROM
2 K Dual Port RAM
M_C_ 1420? MK1420 would be an oscilator
Do you got some detailes pictures?
To me this looks like eitner a Z80 coprocessor card
to run CP/M, or, more some kind of control interface -
that's what the DB connector would suggest.
Betronix was/is a small company here in Muncih (haven't
heared of them in years) - I'm not shure if it's related.
Gruss
