In three mailbox appeared three virge cards: one 325 and two 375 DX ones. The 375 did indeed prove not to have the correct ram: image shattered. The 325 did in fact have the correct ram and now my Stealth SE has the full 2MB :D To be more precisely: the SE has two soldered chips: NEC 424260-70 The …

For long term storage and it's backup, don't go cheap. I use a modern computer with enough space to store everything I like, and I backup that disk every now and then. Any CF card reader will do to transfer data from modern to old. I consider all storage on vintage hardware lost before it's in use. …

So primary master and slave are occupied. That leaves some options. 1. Get another IDE channel. Probably the easiest and cheapest route. This does need some understanding about irqs. Usually a primary IDE channel users irq14. Your BIOS searches this channel for ide channels, if it find one it sets …
"new" (baby) AT based computer... what to choose?
Posted on 2021-03-06, 16:34
A few months ago I got a nice AT computer case. It has all you'd like: turbo button, 3 segment display (188) and enough space to house a full AT motherboard. This is not about getting the fastest system of its generation. I'm mostly looking into filling the biggest gap. These options I have …
Re: Intel 440BX and Pentium III 1.1 Ghz
Posted on 2021-03-06, 14:17
If you get a Pentium 3 the multiplier is locked. The motherboard can't force any other multiplier than is set in the CPU part. So your board may max out at 8x, but the CPU ignores this and will actually run at 11x as it is designed for. If you lack CPU support in BIOS it may cry out some crazy …
Re: Which USB 2.0 cards for old motherboards
Posted on 2021-03-06, 14:02
I've built-in USB on my socket-7 motherboard running Win98SE. My problem is, A) I don't have the cable from the motherboard pins to provide USB ports B) I don't know what the USB chipset is and C) I don't know what the pinouts of the pins in order to make a USB cable. Which would just make it …
Re: Problem with Sound Card and CDROM

No. The basics of the drives differ too much. IDE (atapi to be more specific) uses a different pinout and signals than say Panasonic or mitsumi. Only Really old drives do support these protocols, and you'll probably only get 1x or 2x speed drives. Most 4x and up are atapi with regular IDE pinout. ( …

In my collection most stuff still has spinning rust as main hard drive, but I try to put in a CF adapter when there is an IDE channel free. I do have a SD adapter, but I'm hardly using it. It always feels like SD cards will burn up much sooner then CF cards. On some systems I also have SCSI but …
Re: Fake or Defective Delta EFB0512HA 50mm fans?
Posted on 2021-03-04, 10:16
5v to 12v shouldn't do any harm I guess. I use that trick a lot and haven't had a single issue with that. The ground wire is basically a 0v line, and all that matters is the voltage difference. Technically you could even connect+12v and -12v to get a 24v fan run at maximum speed Or+5v and-5v for a …

Ten PCI graphics cards... Six VLB... Fifteen isa. None with usable and removable chips (without desoldering). Possible solution is on its hand: this week or next one I'll receive another bunch of S3 virge cards, just to harvest the ram chips from the sockets 😁

Recently I started to disassemble a VLB cl5428 which has a bad PCB (front to back angle 15' and no readable image until I force the PCB streight a bit, but still weird character) Took off the RAM to upgrade another 5428 :D I guess I'll keep the chip itself just in case I need one some day. Also I …

Vintage or not: some family member have me an old laptop, an Acer Aspire 3100. Sempron 3500, 1GB DDR2 and ATI 1100. At least it's legacy as it no longer had and practical purpose for anybody, was designed for win vista, and runs xp at its best. The password was long forgotten, so I thought: what the …

The ram chips I tried were not reported, neither the chips from the 5428 when I swapped them. I guess I could see if I've got some more chips the test... To be continued.

That would be a pity... But could be soldered on if I knew what is needed here 😀 Any ideas? Would this be the issue, or would these be used for something else? - R70 - R114 - RP1 I also noticed there are a lot of other components not places, so maybe this wouldn't be?

I don't know for this thread, but I'm interested by it for UH19 :) Can you give me at least some details about your motherboard ? What UMC chipset does it use, does it have 30 pin slots as well as 72 pin slots or just 72 pin slots ? There are two candidates on UH19 so I'd like to know which one is …

Maybe a silly question. I'm about to upload my BIOS from my Aquarius MB-4DUV rev 3.1 somewhere on the forum, but I'm too lazy now to take my whole computer apart and take a photo of the motherboard. Does the BIOS still being in the 486 BIOS collection thread? Or would you like it somewhere else to …

My fastest vlb system contains this hardware: Aquarius MB-4DUV, cyrix 5x86-100, Promise cache controller (VLB), 32MB ram, some VLB i/o card for com/lpt (ide and FDD are disabled in favour of the Promise).
