The NAS-SYS Toolkit comes in two 2708 and is adressed at B000..B7FF.
It is designed for NAS-SYS 1, Naspen and the 8K Microsoft Basic.
I found the original Toolkit and Naspen EPROMS in my EPROM box,
and now, these EPROMS are still working and heating on the RAM A Board.
The suggested memory map was:
|C000-C3FF||NAS-SYS Debug 3.1||1*2708|
|D000-DFFF||ZEAP 2.1 (with the “:” command)||4*2708|
|–||–||12 Eproms: 8 on N2, 4 on RAM A|
|E000-FFFF||NASCOM ROM Basic||8K ROM|
The Toolkit has the following functions:
|Keyboard:||Automatic keyboard repeat feature
(incompatible with NAS-SYS 3)
|Printer:||A Printer Routine with handshake
don’t know, if it was a parallel or serial printer.
Serial handshake is possible with a small hardware modification.
|Main Menue:||(displayed at startup EB000 )
As the ZEAP 2.x Package, the NAS-SYS Tookit checks, if it is run out
There are also some patches for the Toolkit to work with NAS-SYS 3.
