NASCOM

Software, utilities and documentation for the Z80-based NASCOM computers.

PolyDos - code and documentaton for this excellent NASCOM operating-system
ROM - NASCOM ROM images (monitors etc), most including source code
converters - scripts for manipulating NASCOM disk and binary images
doc
- NASCOM 1 RAM expansion (tested) -- see nascom1_expansion for PCB
- NASCOM 2 RAM expansion (untested)
gm808_eprom_programmer - code, photos and documentation for this 2708/2716 EPROM programmer
hw_sim - verilog simulation of the NASCOM 1 and NASCOM 2 video sub-systems
m5 - a very simple "high-level language"
nascom 4 - a NASCOM re-imagined for the 21st-century FPGA age
programs - miscellaneous code
nascom_kbd - Uses a Raspberry Pi Pico to interface a PS/2 keyboard to the NASCOM
sdcard - Arduino-based SDcard storage. There are 2 versions:
- A version that connects to the serial port instead of a tape recorder, and works with NAS-SYS tape commands
- A version that connects to the PIO, with all supporting software to run PolyDos and to extract data from your old floppies
- NEW: a PCB and a detailed user guide
nascom1_expansion - a 100mm x 100mm PCB that breaks into pieces to provide sdcard, RAM card and connector adaptors
