Does anyone know if early Compaqs, specifically the Prolinea 3/25, had a keyboard combination that could switch between normal clock speed and a reduced speed? I don't know if this Prolinea allowed this, but I would assume Compaq didn't employ many different methods of this just to keep...

Random question. Does anyone remember a DOS screensaver that bounces a white ball (or more accurately, a white circle) all over the screen, and could be activated manually with CTRL-Z? I've downloaded a number of DOS screensavers, but none were this.

Anyone know how to convert .woz files to .dsk? I have this .woz file I got from archive.org (attached) that I'd like to convert to a format that will run on linapple, which doesn't support .woz. I'm testing with Applewin which can load .woz files, and that works. I tried the woz2dsk perl...

Can anyone figure out what card this is and configuration for it? I can find the datasheet for the chip, but nothing for the card. I can reverse engineer if necessary but, ughh. Are there any databases for controller cards like what theretroweb has for motherboards?

I'm sure this question has been asked many times before, but it's a difficult thing to pull out of a search. I have these 4GB SSDs with an IDE connector that cause all sorts of weird problems on a 286. You may have seen a previous post about this: phantom serial ports detected, starts booting...

I bought some of these little SSD boards with a 44 pin IDE connector and want to use them on older systems. It plugs right into a thin client I have and works great there. However once I get it connected to an older motherboard (through all sorts of adapters) it causes weird problems. It will...

I posted this over on Vogons a few days ago, for those of you who frequent both forums. Different username, yes. I didn't give that much forethought. I have one of those 286 boards from eBay that has a custom non-bootable BIOS and no onboard I/O. I put a different BIOS on the board for the...

Has anyone ever played around with these 286 motherboards off eBay that came out of token ring routers? Any luck getting them to work? They are marked "JCS286/SCAT" and apparently do not have fully functional BIOS.

I have a P5 motherboard that of course supports two floppy drives, but I have a third I want to use. I'm an electronics DIYer so I built Sergey's Monster Floppy Controller, but populated only the secondary half, and the BIOS section. I know the floppy controller works because I used...
