This graphics card will not display the BIOS POST screen. However, when the power is switched on, the keyboard's lights flash at the appropriate time, and also pressing the CAPS & NUM keys make the keyboard lights work OK. I've tested this card in a socket 3 and socket 7 board. For each test, I also …

Just one more! :happy: KT133A seems to have been popular with the mobo manufacturers back in the day! This one's by Soltek. It's called SL-KAV75. It's got an AGP Pro port. Currently, I'm not using the "special Pro section" of this AGP port, because it's got a warning sticker covering the "Pro …

Would just getting a replacement chip from eBay be easier? It should just be a case of popping the old one out and putting the new one in I would have thought. Note to self - dig out one of your 486 Dallas boards, buy one of those new DS12887 chips, find out if they can be swapped, report back to …

I just found a step-by-step guide to "hacking" in to the Dallas chip, in order to replace its internal battery - http://www.instructables.com/id/Revive_a_pre_historic_dinosaur_an_IBM_PS2_55SX_/ I don't know whether buying a new replacement Dallas chip (DS12887, not DS1287) on ebay is worth trying? …

Another ebay search is - at atx switch One of the results returned (from pcpartsplusmore-store) shows the AT cable section having just the "P8 P9" plugs, as I don't think you need the 3rd white plug on the end. (I think that was for a specific Dell mobo, or something..)

Regarding PSUs, you can get a simple adapter from ebay, so you can then choose any modern PSU you like. Regarding HDDs, you could use a compact flash card with an appropriate adapter. Ebay is awash with them. Regarding a CD-ROM drive, I've tested a handful of DVD-ROM (reader) drives on 486 mobos, …

I just got this CD-ROM drive from the USA. It was well packaged. It's made by NEC and is a bit unusual because it's only 2x speed, but it does not have a propriatory interface. Instead, it uses the later IDE interface. It was shipped to me in the "slave" configuration, but before testing I altered …

I've just bought some "NOS" 5.25" floppy disks. I think the last time I bought 5.25" disks was in 1986, for my Atari 800XL machine. They were shrink wrapped and "cheap as chips". The circular embossed sticker on the plastic box reads: MD2HD formatted for IBM. They are double sided high density, and …

I just tested both DBs on the Roland MPU-401AT card. If I adjust my headphones built-in volume control and set it to maximum, I can hear a small amount of background hiss (when no music is being played). IMHO, it's at a level which is perfectly acceptable. When music starts, I have to turn down the …

I now vaguely remember something weird about the mx300's headphone port. Its "ohm rating" ? (I think) of the headphones must be …
