/********************************************************************************************************************
2013-07-31 Skeleton Driver [Curt Coder]
2013-07-31 Connected to terminal [Robbbert]
The photos show 3 boards:
- A scsi board (all 74-series TTL)
- CPU board (64k dynamic RAM, Z80A CPU, 2x Z80CTC, 2x Z80SIO/0, MB8877A, Z80DMA, 4x MC1488,
4x MC1489, XTALS 1.8432MHz and 24MHz)
- ADES board (Adaptec Inc AIC-100, AIC-250, AIC-300, Intel D8086AH, unknown crystal)
Both roms contain Z80 code.
