Question about Z80 ISA bus board

Thu Aug 31 17:32:03 CDT 2006

>>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"

Have you tried plugging this one into a running PC to see if there are any
ROM signon messages displayes?  Ultimately, what this thing is may well be
revealed by what's in those 2764's.

Just a thought...
