Did we get our denominator and numerator the wrong way round?

How to 1/2 math then? ;p

Dissected a samsung 1.8 inch drive.

All screws removed. Are you ready for the internal beauty?

HDD magnets are fun to play with, especially from 3.5" drives. 😁 I saw one guy use a bunch of them to hold his son up against a metal building (through his clothing).

Got hold of another box of my floppies from when I was a kid. Started the process of going through & backing these up, looking for interesting or rare software, unreleased drivers, etc. I'm not sure how many of these have survived intact but initial results are promising.

BTW, I love this. Did you ever make a C64 or Atari 800 "flippy" disk by notching out a write-protect hole in the other side, doubling its capacity for free? I did, loads, I even had (have!) a special punch tool for it.

Apparently my child brain followed the logic and thought this is how you make a 3.5" double-density disk into a high-density disk. I actually found a few of these. Wonder what's on them and if they're even readable...

Threw in a keyboard and an optical mouse. They are not the best, though for a start, it will do for the person that buy it. As I said, I have put it up locally, because it is too heavy to ship at a decent price.... (it was a hard choice, though I need the space)

Ah, i have one of these babies running in my garage. When i'm working overthere i use to either play some youtube content (at 480p through VLC player) or enjoy some mp3s, and last and most important being able to have a few PDFs opened with some manuals or schematics. I'm only able to run all of this with Lubuntu which also allows to have Skype and Steam chat running in the background through pidgin.
The upgrades it had was a Pentium 3 1Ghz, a PCI-SATA card for bigger and faster harddrives and a PCI geforce 6200 video card.
Also it is quite neat that it has a built in speaker.

it worked on c64 because disk drives had 1 head (one sided). in the case where drives were already double sidded, notching for extra capacity was very unreliable because the media wasnt made for it. HD disks had different magnetic coating to handle it.

notching 720kb DD disks into HD 1.44mb disks had a poor track record

What do you have that uses 20w-50? old VW?

True... Though you got 1.44 mb disks for temporary files, at 1/3 the price 1.44 disks were sold at back in 1987/89.
A couple of years later, they cost about the same. And when they hit the 16 US Cent level a piece, we just bought 100's of them.

Yeah... They are wonderfull little machines. No agp though, wich sucks. Yet they are small, and if one can settle with PCI cards (GF2, TNT2, V3), they are actually good machines. Can only be used for Win98 though, as there are no ISA slots. It is just a wonderfull Windows machine.

Played around with my LS486-E trying to get it to run with 60/66 Mhz front side bus.
At 50Mhz the second level cache is not able to cope(only 4 banks so no "interleaving" I assume) thus I had to disable it. Speed is ok, but now I wanted to make up for it with ram at a higher frequency... luckily a vogoner named "rad" reported that all jumpers shorted yield 66Mhz fsb. In addition JP19(undocumented) guarantees, according to "rad", that the other subsystems can run with external cpu clock/2 - and so within specs.

"Worked", but no ram module was able to withstand the test. I've already ordered one 50ns, 32MB stick and I'm pretty curious if this will be able to alleviate the current shortcomings.
There might be other reasons which I'm not currently aware of, of course!

I would love to have cache that worked at 50mhz fsb but I was not able to source one with 12ns and a 10ns tag... given such cache exists...?

What CPU's have you had running successfully on it? I had some problems with dx2-80, yet the one in my list below, ran stable at stock speed. Even a real Amd 486dx4-120 chip did not run. So I have actually never overclocked my board at all. Shure I had issues with my board at first. When I got it, it would only run 5volt chips. I solved it with a new regulator.

Did a few scans of one of an old magazine. Maximum PC Vol 1 Issue 1 "Dream machine '98"

Both an Intel DX4(WB) and an Am5x86/133/ADZ ran at 50fsb. Only the Intel was able to run at 66 since the AMD interprets 2x as x4 as far as I know.

At the standard 25/33/40 Mhz I have not come across any problems with 3V nor 5V cpus. TI/DX2-80 ran fine... but be aware that I do only have a small array of chips to test.

Ran a few benchmarks on my Slot A Athlon 600 + Voodoo2 SLI rig and it keeps giving me some weird results. Unreal gets me around 54FPS @ 1024x768, which seems about right, but then 3Dmark99 gives me 3670 3DMarks + 10135 CPU 3DMarks (800x600), which seems way too low...

I worked at an oil change place back when I packed a lot of this stuff up, hence the boxes. That said, I was driving a 1.5L Mitsubishi Mirage at the time with a burned piston ring & did run 20W50 in the summer in an effort to not burn all of it off. Drove it like that for at least two years. 😜

Finally got around to flashing a Voodoo3 2000 PCI card from a Mac ROM back to a PC ROM. I no longer had any need for a Mac capable Voodoo 3 and my AMD K6-2 450 system needed a Graphics card. This particular PC only had SIS 530 onboard graphics, so the Voodoo3 is a vast improvement and working well. I might add a fan to this card at some point, it seems to run much hotter than my other Voodoo3 cards.

Also started the first phase of my attempted repair of an 8088 era motherboard - a tantalum had snapped off so I soldered it back on. Just waiting on delivery of one of those Silver Conductive Pens to see if I can repair the scratched traces. No idea if it will work or how reliable it will be, but I'm not really too great with soldering on wires so this is the best I can currently hope for.
