Ooh boy I've got a dozen but I'll post here a (shortened down) version of my most "weird" encounter: It begun when I wanted to pop in a P233MMX into my Shuttle HOT-555A board (rather affectuonously known as "Shittle Hot garbage"), set the jumpers correctly and booted it first try, or so I thought... …

Mine is just a ceramic Pentium 133 that I extracted from one of my old rigs to swap it out with a P233MMX (which I later found out that it might be a dud, I have terrible luck with computers). At some point I may just change it... But I'm undecided on that matter.

Bought a motheboard based on rather uncommon Socket 5 chipset - VLSI SuperCore. Soon to be added to my Early Pentium Chipsets survey. As soon as I figure out the power connector pinout. https://dependency-injection.com/wp-content/uploads/2020/05/DSC_7302-scaled.jpeg Is it not a standard 20-pin ATX …

That CRT might need to be degaussed, also, I'd recap the whole machine if I were you, some compact Macs were known for suffering from leaky SMD capacitors. On top of my head I know that the following compact units are affected (I'm excluding the other Macs) : Macintosh SE/30 (the SE seems to be …

Perhaps one of the pins is for luminance (or Luma, aka "Y" in Y/C), another pin is for Audio then the rest should be ground. You could try and poke around with an oscilioscope to find a potential video signal... But that's something that might be hard to grasp for some people.

Ok... so here is what all the "secrecy" was about.

Here are two more pics, the one with the U-bolts was a unit I already had, it was made in 2002 and has a A20JKU10X tube, whereas the right one is from 2000 and has a A20JKU11X tube. The pics in my initial post were when I had bought the right one and its twin.

My favorite TV? I'd say it would be my parent's old Samsung PS42A456P2D, we won this behemoth in a contest... At 42" it might be small by today's standards, but when new it felt huuuge! I love that people think it's a LCD when they look at it, but when you see the deep blacks and feel the weight of …

First computer I ever bought was a "Summer 2001" Indigo iMac G3. But the first PC I had was a IBM NetVista tower, it looked like a A22P but was beige. I cannot remember for the life of me the model number, that one was a hand-me-down from my father.

Tried that, same problem. I even put a small fan blowing on the VRMs, still no dice. I even had set the multiplier jumpers to run the P233 at a lower clockspeed, it only further worsened the problems.

Hmm that's really bizarre because on mine, whenever I put a P233 in it, the board starts behaving unusually (needs to be hard rebooted, hangs randomly, Windows does not even start and sometimes, I get data corruption bugs), everything goes to normal when I put back my 133MHz Pentium. I don't have …

The UMC IO version should be the correct one for this board. Funny now you mention that, I've got later Rev. of this board (mine's a HOT-555A), could you check if your board works with w95/98 with a P233MMX?

Just put a passive DVI-I to VGA dongle on your card's DVI-I port, it's not rocket science at all. Else you will need an active converter (such as a HDMI to VGA or DP to VGA).

Guess what? I somehow ended up with two other PVM-9042QMs all of that for 20 euros. I guess, 3 is the charm? The seller also had a BVM but it wasn't working, what a pity. Now I'm going to give one to a friend and keep the other one among with the rack shelf. I already have a 9042QM that isn't as …

AFAIK no early Macintoshes used 5.25 FDDs, except for the "Twiggy" 128K prototypes. Unless of course, if you count the Apple II line as Macintoshes, but that's a whole different animal.

The 3rd board looks like to be from a Olivetti M24 EDIT: Nevermind. It looks like it has a NEC V40 CPU, so it can't be a M24 motherboard, as the M24 used a 8086.

Among that stack, the Jetkey chip is just a plain old KBC, can be useful if you've got a old 486 mobo that lacks one... I think I can see a chip with "MR BIOS" written on it, next to the Jetkey. Could be worth a shot trying to find a EPROM reader and dump its contents.

ISTM that 10K/15K RPM SCSI HDDs seem to be more fragile, I've had a Hitachi Ultrastar 15K and it didn't work for long before it exhibited the same symptoms (click and whirr before failing altogether). Some SCA80 drives may need some jumper adjustments to spin up... iirc in servers they were set to …
