Hi,
I am working with some small CP/M 2.2 systems and would like to find more info on the GSX graphics system.
There is some information about programming and a few drivers but much seems to be missing.
My ultimate goal is to write some terminal screen drivers for the 8080/Z-80 GSX system - not for CP/M-86.
The latest version of GSX-80 seems to be version 1.1 from November 1983.
So far I found scans of the "GSX-80 Programmers Guide" (2 versions) and some .PRL drivers for printers and plotters, but no example source code for driver development.
What I would like to find is the GSX Programmers Toolkit for CP/M-80 with its software and documentation.
A DR newsletter states "GSX Programmers ToolKit is available for 8-bit and 16-bit systems and includes ISV redistribution license, tailoring tools and documentation."
Also it would be nice to find a copy of "DR Access 10 für CP/M-80" which may include more drivers.
I found a copy of an "xterm-Tektronix" screen driver by Udo Munk from 2014, but no source code.
Thanks,
Martin

- Does someone have a copy of the "GSX Programmers Toolkit for CP/M-80" which could be copied/scanned?
- Any source code examples for CPM-80 GSX drivers? Maybe not in RATFOR but C or assembler?
Thanks,
Martin
