I've been following another message thread about someone whose cmos battery dies after 1-2 weeks. One suggestion was bad bios chip... I don't have the wherewithal to burn a new one, or even figure out what's wrong with the old one, if it's the bios raping the cmos battery 🙁

Oh, I'd say these stores were within a 10 mile radius of my home. I live in a large urban area, so thrift stores and Goodwills are ubiquitous.

Today I stopped by several Goodwills and found... nothing. Then, after stopping by KFC to pick up some supper, I spotted another Goodwill, and decided to give it a try... There were 3 monitors there; two Dells and a Sony. The Sony had what I think was a DVI cable. They wanted $9.99 for the Sony and …

yeah, I tend to collect printers. I've a couple old CBM 1520 plotters, and an Okimate20 thermal transfer... an old canon BJC80 bubblejet portable (still need a battery for it...) and my pride and joy, my Panasonix KXP2135 nee 2130 (I installed the color kit). I've been wanting to get a Tandy or …

I inadvertently acquired this 386sx motherboard, and noticed that it has two strange slots; they're longer than 16 bit ISA; in fact they look like double 8 bit ISA slots. I also can't see where the CMOS battery goes on this motherboard. 386sxMB.jpg Anyone have any ideas what kind of slots they might …

I keep hoping he'll come back, both because I enjoyed his presence but also to get yet more advice lol. I need to replace the barrel battery on my new 286 MB. But I don't know what I can safely replace it with. More on-topic, I need more advice on my T5200's CMOS battery issue, before I go trying to …

I've been looking around, and have had a hard time finding AT cases for my AT class motherboards. Most of the ones I find on ebay are $75-$100+, usually w/o a PSU, and then with another ~$50 for shipping. This puts them in the same range as vintage, (often non-working) 386 systems. I've considered …

I'm so excited... I just bought an 80286 10mhz motherboard with 1mb of ram off of ebay. It's not here yet, but I already know I'm going to need to replace its cmos battery. It has the barrel type cmos battery, currently. Can I replace it with a CR2032 button battery? Should I, or would some other …

What happens if you plug a (in this case 486) CPU card into the ISA slot of another computer? Say I have a K62-300 (cause I do) with some ISA slots... what would happen if I plugged a 486 CPU card into one of the ISA slots? Will it fry my K62? Will it fry the 486 card? Will it sit there doing …

I'm not criticizing you. I'm just sorry no orange gas-plasma display is available. On the upside, a more modern display is going to have less movement blur. I'm less concerned with originality than with usability. That's why I'm worried about fixing my cmos battery issue. I'm torn as to what I want …
