I have the horizontal desktop style case Gateway 2000 P5-75 and I do recall changing DIP switches to overclock to 90mhz. I thiiiink I could have gone further than that but didn't really want to stress the machine out - I've owned it from new and am a bit attached to it! I dropped it back to 75mhz …

That's a 2000s era Gateway mouse. It's definitely PS/2 only. Those microsoft mice usually say on the sticker underneath if it supports serial and ps/2. I've a few of these gateway mice ranging from 1995 onwards and I don't think any of them support serial mode.

I don't think I'd even heard of bus mice until about 3 years ago. What was the advantage of it over a good old serial mouse?

Polymer caps can now be used for much of the range of SMD electrolytics and are a good substitute for tantalum caps as well. I know those exist for the Can types, but do you mean these specifically? https://uk.farnell.com/c/passive-components/capacitors/polymer-hybrid-capacitors/tantalum-polymer- …

I wouldn't be considering non SMD caps. Would SMD MLCCs or Tantalums work instead of the SMD electrolytics, and which one would be better?

Hey, I was taking apart my Dell 466L machine to take some photos of the board and realised I probably need to recap it as the SMD caps were definitely leaking on the board. I noticed there seemed to be two different sets of pads for each capacitor. I asked about this on the eevblog but figured I'd …

Looking for a Gateway 2000 System CD for a P5-75 model (MFG date 02/1995) I'm not having much luck finding my CD at all. I'm wondering if I ever actually had it now, as I can't recall this particular machine arriving at home boxed up, so I think it came home unboxed from my dad's company at the …

Cool! I don't have the cache upgrade for mine. Did yours always come with it? I need to borrow a better camera before I try take more photos as mine aren't coming out great - I have quite an old phone. Will get back to you..

Also, FYI - I'm running a standard ATAPI CD-Rom and IDE hard drive on the same cable to the boards lone IDE port. The BIOS on these old machines will never detect a CD-ROM drive - the driver and MSCDEX takes care of getting it working. Set HDD to Master, CD-Rom to slave. HDD on connector on cable …

So... seems my board is different! I don't have the same RTC chip, and where yours is, is unpopulated on my board. I'm using the spot right beside it on the board, which has an avafem av9155 chip. It's getting 5v on it's VCC pin. The capacitor and resistor you show in your photo is not populated on …

I'll try get to this as soon as possible... Not to do the typical "It's old! CHANGE THE CAPACITORS!" thing, but I do notice the solder joints around the SMD caps on my board are really dull looking, and yours appear to be the same... Are they leaking do you think?

Nice! I have the Dell 333P - really love that style of case 😀 I hope the battery leak hasn't affected any of the traces to the keyboard ps/2 port as they'd be under where the battery used to sit. My battery leaked too but luckily didn't affect anything.

It subsequently stopped working again and I haven't had a chance to fix it. I'll try glue it at some stage but I was half hoping someone from the 3DO scene would be able to knock up some replacements for that which I could buy 😀
