IBM PGC

[mt777]

Would like to test 5175 monitor in native mode. But can't find working software. VDI and VDIPGDSYS are loaded.
Downloaded this via webarchive: https://wiki.mamedev.org/index.php/Driver:PGC
but menu is different and doesnt ask about PGC output.

The early versions of AutoCAD (2.X) support the PGC natively. there is a version of Cshow that does as well, I have used both with success. no software drivers needed as the programs supplied their own drivers.
look here for cshow https://www.seasip.info/VintagePC/pgc.html
