>>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...
