There's a reason they sarcastically call leading edge "bleeding edge"... a neophile type PC enthusiast who had to have the latest and greatest always had a flaky science experiment of a machine waiting for drivers to catch up. Many enthusiasts were on the "rolling upgrade" plan, meaning CPU this …

Also local source popped up for Perixx modern USB keyboard with a trackball between letters and keypad, are they good or bad, I've always wanted one of those Ms with a trackball in. This would I know not be the same, and if I was …

This SL4100/D4100BL "Cobalt board" has a footprint for a SCSI chip and 50 pin, didn't notice a Patriot, Ambra or other model that advertised SCSI while I was trawling through stuff though, but the PCBBS files have SCSI drivers, not sure if for that or an add in card. Didn't get a whole lot done …

I am pronouncing sentence on one of two Asus P2B boards... They both arrived in a scrap lot years ago, both had BIOS, MOSFETs and voltage chip removed already, there is a possibility that some other major part fried, leading to them being cannibalized for other boards. Ergo, even if voltage …

Sometimes you get a worn out jumper cap that won't contact well, causes you all kinds of weirdness.

I dunno if that "2x floppy interface" is confusion creeping in from things that happened later but ended up causing questions about the past, like ATA was just ATA until serial came out and now it was PATA, (I can't find PATA port labelled in 486 manual! etc). In that from 1981 into early noughts a …

Awesome, got some older newer laptops which will benefit from this. I'm "into" other projects/eras at the moment though, will have to revisit.

Nice, victory tastes best after the long struggles. [hr] So not too much to report, pulled riser out for good scrub, it's got a set of holes for a backside ISA slot, bringing total to four, and the hole is in the back of the case, I don't know if I can resist. Got the Dallas eased out, was so stuck …

Is it too late to take it back, the winchip? ... Just kidding, it's just a very very narrow range of circumstances where you can put that in a system and not find a drop in CPU that's faster. They run pretty cool though, and prolly fly in win 3.x.

Yah they're not bus speed "locked" like PII, PIII up, no FID to fiddle, just set it at what you want.

BIOS setup settings where the 1x 2x 3x is are not sticking at the moment, it's defaulting to 2x, but possible breakthrough below leads me to think it IS a 3x, just gotta fix the dallas....

Yah, I like the splash, seems "impossibly" cool for IBM, like management weren't around when they did it... only recent one I've had that I like near as much is a Red Fox PIII board.
