The PC has a 5.25" HDD , model BIGFOOT QUANTUM TX(A). The CD drive is not working, but is recognized by the BIOS and the OS. The RAM is 64 MB, …

Found this 286 motherboard with a nice harris 20 mhz cpu. The battery has leaked though no major damage. It has a quite rare CPU CS80C286R1787 that from the search it looks a custom 20 mhz harris CPU. It has 7 ISA slots and SIPP ram sockets. I don't have any SIPP ram though. Speaker seems to have 2 …

Oh I just noticed the first board, there is nothing there. I wouldn't bother with it yet, the other board needs a lot of work and is in a much more salvageable condition. Are these "before" or "after" photos? It seems like you need to literally desolder and remove everything, and I mean not just …

Most probably yes, they don't look too bad. But: you really need to remove ALL sockets, connectors and components around the area until you stop finding battery damage indications. Cleaning what's visible is not enough, some times the nastiest things are hidden. Then check the traces with a …

Hello. Bought two motherboards, both with soldered AMD 386 dx 40 and empty coprocessor socket. Both had a nasty Ni-Cd battery that leaked its contents and ruined the motherboards. The small one seems to have just eaten the protective paint. It has been cleaned with white vinegar, contact cleaner and …

Found this 286 16 mhz mb, looks beatiful and nice, no battery damage. I tried placing a ISA 16 bit 512 kb VGA card, psu and keyboard. Turning it on has the MB buzzer beep three times. American Megatrends bios 1990. The motherboard is unidentified. I placed two sticks of RAM 30 pin 512 kb (2x256 …

Yeah, sounds like that one. The socket though is too large for a 3167 or 387. It's a 145 pin with a strange shape. Anyway, what kind of damage did this MB took? It looks more than the leaked battery due of those strange oil-like stains. Can i run it safely with the external BT connector? Edit: too …

Found this 386 motherboard. Really tiny and compact, 5 ISA slots with 486 ( 168 pin PGA) support. Unidentified so can someone help me recognize it? CPU is a soldered AM 386DX-40. Looks a lot like this one https://theretroweb.com/motherboards/s/informtech-it-am33-40-dlc I doubt it's a 486 socket. …

[...] It seems to be a 486 dx with VESA motherboard, the settings on the board say "JPX 25-33-50 cpu clock" so i assume it may only support the first 486dx generation (need help to see if i can place a more powerful cpu on it) On the contrary, 1st gen would probably have 16 and 20MHz as well. …

Hello. I just bought 5 vintage 486 mainboards, I got them cheap and I wanted to repair the damaged ones. Some have obvious damage but I have no idea on the extent of the damage. Some don't seem to be recognizable so I have no idea what jumpers I need to set to set up the testing cpu. Here's the …

Safely test them? Damn, well I guess balancing on a tightrope over a live volcano while powering them up is out then. But anyway, basics first, check all power lines to ground for shorts. Yeah. While it's not obvious by the photos (thanks Vogons for 5 photos limit), I've checked some of the boards …

PC screams late dos but what style of games are you into? 3D shooter, RTS, Racing, etc? I am mostly into classic D&d Rpg games, RTS, Simulators and a bit of shooter. One that I have installed is Sid Meier's Alpha Centauri and Star Wars: Dark Forces. I also don't want to miss out the classics of the …

What do you mean with PS2 compatible? From what I know, your mouse either has a PS2 connector or a 9 (or 25) pin serial connector. If there are no ps2 ports on the motherboard then there is no need to try with PS2. You can only install a serial mouse. It means that the mouse I have can use an …

Does BIOS have anything about disabling PS/2 mouse. Windows is probably picking up that the chipset supports PS/2 even though it's not implemented on the board. -If not it doesn't really matter Windows can happily have a PS/2 and serial mouse. If you download and run cutemouse from a dos prompt …

Update after being able to get that MB working. I've removed the diode and used wires to a CR-2032 Battery holder so now the cmos is stable. Now, I've got that PC running and it boots in win 95C correctly. Unfortunately though, the MB is giving me the error about a ps/2 mouse not plugged despite …
