Cherry G80 or 81? Looks like HAU caps :) On the back side of keyboard it says: G80-3000 HAU/04 What does HAU mean? Nice! G80: mechanical Cherry MX switches -3000: board design. The 3000 is *still* in production, the longest run of any keyboard, but this is a very early model. HAU: H - doubleshot …

It is totally safe to underclock with the usual ranges of multipliers and FSB (66MHz minimum). However, only the FSB part can actually be underclocked, since intel locked the Multiplier to a single value on all retail Pentium 3s. Your CPU will remain at 7.5x. Yep. Corollary: if you want a P3- …

I never understood why to upgrade memory of any isa video card. They are not fast enough to run anything at higher resolutions that would require more memory. Generally even 512Kb is more than enough for any isa video card. For gaming you are correct, but certainly back in the day when these things …

Cool stuff indeed. Don't those CPUs massively overheat a poor little SS10? Just found 4x 64MB DSIMMs on an auction site. Did a lowball offer that was accepted right away. Also found both of my preferred electronics vendors stock new M48T08 NVRAM/RTC modules, so will add one to my next order of …

Sparc boxes never had the sort of snappy UI experience you had with SGI, Apple or MS, they were heavily optimized for background tasks. That said, as you mention, they tended to be very minimally equipped when it came to RAM, and no system ever felt good thrashing to HDD because common tasks had to …

If it was visible on the photos, caveat emptor. If not I suppose it depends on the price&expectation rasied. If you pay for scrap, that's what you can expect, if you pay for working good stuff, they owe you an explanation and some form of resolution.

Today's catch: ATA IDE HDD 80GB and 13 x 30-pin SIMM EDO RAM. Cost me 5 EUR on a local auction site. 30p EDO... haven't seen that before. What kind of system supports it? Some very late 486 chipset with anachronistic 30p SIMM slots? Or something non-x86? Speaking of which, tomorrow I'm picking up a …

The original here was a 1287, I replaced it with a 12887. But either way, the problems occurred when the original 1287 was still in the board.

That's not RTC issue, strictly speaking. These chips also have some SRAM that serves to store the so-called CMOS settings. BIOS keeps HDD parameters in there so with the battery dead but the chip still present these settings will be there after a reset (but will fade once you power off). However …

The P5A plays very badly with a lot of ISA cards, so even if you don't need more slots you might get into trouble with it. I kept another simple i430FX system alongside my P5A for my multi-sound-card build for that reason - but I'm replacing that with an So4 build once I fix a few things on the …

Which revision P5A do you have? 1.05 or earlier has the older D/E revision of the Aladdin V chipset which can only cache 128MB of RAM. With 256MB you'd be outside your cacheable area and would have lower RAM performance. In that case, try dropping to 64MB if possible - it will probably run better, …

Manuals only show what was available when they came out. If a motherboard has three jumpers for multiplier (as any motherboard must with settings for 266MHz/400MHz or higher), it can be set to 5x and 5.5x - and in the case of K6-2 also 6x: One jumper: 1.5x = 3.5x 2x = 6x Two jumpers add: 2.5x 3x …
