Hi,

This is the motherboard for my 386 PC - http://stason.org/TULARC/pc/motherboards/D/DE … ml#.UcCVOD60Nz0

I was wondering in regards to the "Proprietary cache card/shunt card
JCACHE" and VGA ram memory slots.

The cache slot has just a blank circuit board in it with no chips on which I guess is just there to bridge a circuit. The machine won't boot without it. Should I look to add some cache memory in here? Does something like this look like the right thing? The connector seems to match.. http://www.ebay.co.uk/itm/256Kb-Cache-Memory- … =item4173fb86ca

Also, is it worth me adding some VGA memory chips? The upgrade slots are currently empty so i've got 256KB VGA memory to work with.

Just curious if there's anything I can do now that it's likely I can source these parts for cheap.. I know the FPU is a pointless upgrade so i'll skip that 😀

Thanks!

Cache would be nice, but finding the proprietary module is going to be extremely difficult at best. The thing in the eBay listing is a COAST module for Pentium systems... completely different from what you need.

The video memory should be easier. It probably takes one of the common type chips... most likely 256kx4 DRAMs, but you'll have to check to be sure.

That's too bad that the cache will be hard to find..it'd speed up the machine somewhat though? and I take it the VRAM would only allow me run higher resolutions in Win 3.11?

I'll double check it tonight. Is there any software I could use to check this rather than taking everything apart again to view the CPU label?

I definitely have sockets for extra video memory. Does your machine not?
