You have just added a disc drive or two and CP/M to your Nascom 2. After a few minutes gloating, you try the Digital Research editor, ED.COM) and find that it is a pig to use. Then you discover that the assembler provided only knows 8080 codes, instead of speaking Z80; even worse, it uses weird mnemonics designed to confuse anyone who is used to the Zilog set.
You could buy Diskpen and Macro-80 to solve your problem – if you have enough money left after lashing out on the discs. If you did, you still won’t be able to run all your old programs. In this article I provide instructions that will enable you to produce a CP/M program that will pretend to be Nas-Sys 1. I also provide some machine code which enables the new version of Nas-Sys to read from and write to the disc.
To avoid possible problems with copyright, not to mention space in the magazine, the Nas-Sys code is not given. If you got your Nascom by legal means, you will find it in your manual.
