System Development Tool 128K c 1988

Post by Maskenlos »

Hi all,

since many many years I have a ROM replacement PCB which has 3 time 64K Eproms. With some help of Chris we read the content and found 2 things:

1. A modified Version of JS

2. A tool called "System Development Tool 128K c 1988" which I never heard before. I isolated the first 16k because I thought that only 16k could pages in from C000 onwards and I loaded it into Q-Emulator. Starting screen as attached. Also it provides a lot of new commands, which I never heard before like "IBOOT", "SBOOT", "MOUSE".

Anyone any idea what it is about?

Regards,

Stephan

Eprom board arrangement looks like this.

I managed to decipher "(c) Busy Bee Soft" on the rear.
