Picked up these two boards.One with 386DX and a version of 80387DX. The other with Harris 8C286-15 and ITT 2C87-12. board386.jpg board286.jpg The 286 board has PTL286-78 label but I can't find a thing about it. It's populated with 4 SIPs and has empty chip sockets for chip DRAM. The 386 board has a …

Hi! new to the forum and vintage computing in general. Recently came across what I thought was a 286 (it was in an APC 286 case) but after looking at the boards closely I'm beginning to think it's not. Attached are a few pictures of the system I am trying to identify. I really appreciate any and …

I have one of these in storage somewhere. Haven't touched it in years... I'll try to find it to see if it still charges. EDIT: Mistakes were made... Learn from me, check all your old stuff from time to time. 20250603_144608.jpg 20250603_152952.jpg So, it looks like I have a GH388, a PH388 and 3 x …

can't you just turn off CSM and test it that way? That is my main machine, so no, I will not do any tests on it... Sorry :) What I did so far was setup a qemu virtual machine with UEFI firmware (Tianocore) and install Windows 10 on it. Windows formatted the virtual hard drive and created the UEFI …

Odd that the 74LS245's were socketed... here is VLB Ref design schematic from Cirrus 1994Tech Ref...there is an ISA one in that book too Do you also have the schematics for the GD5428 and GD5430?

Do you also have the schematics for the GD5428 and GD5430? It would be quite useful for me. The schematics for the 5426 and 5428 are identical. The common data book scan on the internet is a collective data book describing the whole family of PC-type graphics chips, the 5420, 5422, 5424, 5426, 5428 …

There is a "public" version of the technical manual for this family of chips on the internet. It shows what each pin on the chip does, so you can try to use it to figure out what the jumpers do.
