Closed 386DX40 +387 OR Microchannel 486 Upgrade Board

[armankordi]

Hi, looking to upgrade my PS/2 70, but can't find a suitable upgrade for it.
I'll take any old 386DX-33 and/or 387-33 OR 486 upgrade board.
Willing to trade, ask me! I can upfront offer a 386DX-16 & 387-16
PM for anything, thanks.

Are those chips pga? I have a 386-40 and 387-33.

Yes, both 386's are pinned. Would the 40 & 33 work together by any chance? Or would I need matching CPU and FPU? I'd prefer a 386-33.

They once were in the same board, so the FPU was slightly overclocked.

Ok, sounds good.

I'll grab them tomorrow for a picture.

Here they are.

Do you have a 386-33?

No. But if you use a lower speed oscillator it will probably run at 33MHz.
