This is an attempt to list all “official” hardware related to the Nascom computers.
If anyone has anything to add, please let me know!
| NASCOM-1 | The original computer that started it all |
| NASCOM-2 | The second version – much enhanced |
| NASCOM-3 | The first Lucas Logic version – basically a NASCOM-2 in a case with a power supply and small expansion bus. Optional disk drives. |
| 3A & 8A Power supplies | +/- 5V and +/-12v power to the people! |
| Buffer Board | Required to connect NASCOM-1 (only) to the Nas-bus as the processor signals were unbuffered. |
| 12-slot Motherboard | 77-way edge connectors (Not required for the Nascom 3, which had its own internal motherboard within the case) |
| RAM Board | Available in 0,4k,8k,16k,32k. Also had 4x 2708 EPROM sockets. |
| RAM (B) Board | A later, more flexible and reliable RAM board but without EPROM sockets |
| I/O Board | Various combinations of ICs up to 3xPIO 1xUART 1xCTC. |
| Floppy Disk Controller | What it says really… |
| The IMP Printer | Slightly non-standard dot-matrix printer |
| Nas-Net | Serial port networking system for 1 master machine & up to 32 slaves. |
| Nascom Test Board | For testing nascom systems, presumably… |
