Hi,

Now bit better details here...

Okay, if it is 20pin DIP sockets, fetch 256K x 4 bit 60ns or 70ns
DIPs (the ramdacs on these old computers is not that high to require
60ns). Off a old video cards is easiest, very common item.

If it's SOJ, unsoldering chips from 2 or 3 chip 256K pair of simms is
required. I haev not seen 20 pin SOJ sockets. This SOJ are
soldered on directly to PCB or regular DIP sockets.

1M will only give you 1024x768 at 16 or 256 color I think.

You might want to move up to 2M video card if u need
windows acceleration and more color at 1024x768. S3 Trio 64V+ is
very nice one if fully expanded to 2M.

Most of 1M maxed video cards aren't as fully featured compared to 2M
video chipsets.

Cheers,

Wizard
