JUst got an AST Desktop for free from a friend at work.
It has a crappy P100 which I have upgraded with the max cpu it can take...a whoppin' P166 😁 and 128 meg's or RAM...also max for this 1995 PC 😉

What sucks about this PC...typical "business PC" disease a lá Dell, Compaq, Packard Bell etc is that you're trapped into their custom hardware...
For example I can't disable the onboard video which is now only 1mb but upgradable by 4 sockets which are smaller than the typical sockets you find on most gfx cards.

This is what the sockets look like

Has anyone seen a gfx card which has these sockets so I can snatch ram from it?
The ram type is suppose to be:
256KB x 8 70ns DRAM modules at system board locations U27-U30. (See Options)

In all my years of looking, I've never seen a graphics card with socketted memory that looks like that.

Though, occasionally I do see cards that have that type of memory soldered to the PCB. Your best bet is probably late VLB or early PCI cards. If you use a scalpel knife and carefully slice the chips off the card, you should be able to reuse the chips in your sockets.

Here is an example:

You should be able to find one cheaply if you look.

Nope, his doesn't use 28-pin SOJ memory. They appear to be 24 pin SOJ. Besides, the link you have provided is for SRAM, not DRAM.

I find that two types of PCI graphics cards that typically have this memory are based on either Tseng ET4000W32P or S3 764 TRIO 32/64

Here, this is the best I can do:

Groovy 😀

So you think I can grab one of these cards and cut the chips from this card use them on my (crappy) motherboard?

There is only one concer. I noticed that the card I linked to usesthe s3 765 chipset. I think those were offered with either EDO or FPM ram. The photo is too blurry to verify. You want to make sure you use FPM. If you slice it off carefully, it should work fine.

Now I can run 16-bit color depth at 800x600 instead of 600x480

Whoo-hoo!

Where did you end up getting the chips?

I slaughtered a crappy Trident VLB card...but my crude removal method of the chips damaged the legs of one of the chips so I had to carefully steal a chip from an ATI mach64 PCI card I also had lying around 😎

Amigaz, you could sell it for around 100 to 500 Kroner (if you can find a collector of course) if you make this Dell into a system with a CD drive and what not. Remember it would be better if you sold it to either a Dane, or some foreign guy. Cause making a buck is not that bad.

Won't sell this machine, my plan is to use it for mid 90's DOS games and Voodoo 1 only games.
Will throw in a gameport card, NIC, and a Gravis Ultrasound and use the CS4232 onboard audio.
it's virtually impossible to sell older PC hardware here in Scandinavia.

btw. it's an AST not a Dell 😀

If your GUS is a classic, setting ultra16 to the cs4232 address and having GUS output wired to cs4232 input, you can make a psuedo GUS MAX, the only programs that wouldn't work would be any that were written to be hard coded to the default address of the CS4231 on the GUS MAX instead of reading it from ultra16.
