Dump contains a MS-DOS 3.3 ROM disk, ebay auction shows a Pine Technology PT-319A
|

(SARC RC2016A5 chipset) + 2 other populated ISA16 cards out of 6.

TODO:
|
||||
- Host MB unknown, may be an higher CPU socket;
|
||||
- Jumps in unpopulated RAM area as soon as it banks (PC=ca029 -> 0000:36AF), area may be
|

multibanked instead;
