British microcomputing, rediscovered
One computer.
Many stories.
The central archive for the Nascom 2—from the historic single-board computer to its modern FPGA implementation on the MEGA65.
- 1979
- A new idea of personal computing
- Z80
- The classic 8-bit architecture
- Today
- Faithfully recreated on modern FPGA hardware

Historical context and practical documentation live under one roof—clearly separated, yet closely connected.
The original
Understand the Nascom 2
Architecture, memory map, NAS-SYS, software and the ideas behind the British microcomputer.

More than a museum piece
Machine code, BASIC and an entire ecosystem.
The Nascom 2 was a learning machine, development tool and games computer all at once. This site collects knowledge and software so both can be put to practical use again.
- 01 Monitor commands and keyboard layout
- 02 Programs, ROMs and disk images
- 03 Schematics and technical reference
Current status
The core keeps growing.
SD card access, floppy emulation, CP/M 2.2, AVC graphics, AY sound, joysticks, a real-time clock, UART and Ethernet turn the Nascom 2 on MEGA65 into a living development environment.
