# 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

## Projects in planning

At the concept stage..

* Get NASCOM CP/M running on a NASCOM 2 without the need for a special NASMD PROM
