Just like to share I got my Vermont Microsystems IM-1024 PGC-clone to display a picture, but I am afraid to get more out of it I need some software or documentation.

Its this card:

I was able to connect to my DELL LCD without any adapter. Just connected 4 wires: RGB and composite sync to VGA-PIN13.

To lazy for GND which may explain the bad image quality I got 😀 But I am happy it displays anything at all without converters or adapters.
Resolution is always 1024x768 @ 60Hz.

Also happy it displays the BIOS screen, was not sure if this card works as a secondary adapter only.

CGA emulation also works.

With the PGCBMP.EXE programm I only get a purple screen but no picture is displayed.

There seems to be a Windows 1.0 driver around but its use is quite limited...

So if anybody owns a driver disk or a manual I would be very happy to get a copy...
