| 7 | The photos show 3 boards: |
| 8 | - A scsi board (all 74-series TTL) |
| 9 | - CPU board (64k dynamic RAM, Z80A CPU, 2x Z80CTC, 2x Z80SIO/0, MB8877A, Z80DMA, 4x MC1488, |
| 10 | 4x MC1489, XTALS 1.8432MHz and 24MHz) |
| 11 | - ADES board (Adaptec Inc AIC-100, AIC-250, AIC-300, Intel D8086AH, unknown crystal) |
| 12 | |
| 13 | Both roms contain Z80 code. |
