Ok great ! I have many of the old Dell pages from archive org indexed. Hopefully this matches your board. Unfortunately there are no good pictures of the inside of the front panel.... Here is one main page: http://web.archive.org/web/19961222115021/http://www.dell.com/support/tech/DTA/APMT/default. …

Yes but you need to check which is ground, most 3 leg Tants the outside legs were ground and the middle was positive (not sure why they did 3 legs since the grounds were typically internally shorted except to use as a feed thru). Use a Digital ohmmeter and check that the outside leg holes are truly …

What XPS model number ? Is it a true XPS P90 model ? There should be a model number on the case somewhere. My old XPS has a label with model number on the back, some it is on the front.

Keep in mind that from those companies you mentioned, Seasonic is the only one that actually manufactures power supplies, in fact Antec, Corsair and EVGA had (and may still have) units built by Seasonic for some of their models. The SS Focus, for instance, is a very good series of PSUs. Of course, …

I still have my original Pioneer DVD-304S slot loader from July 2000, and it's never missed a beat :) Some seemed to last forever, some had issues. I've had a few (3) Pioneer DVD slot loaders over the years, but the slot loading mechanism always breaks. I gave up on those back in 2006. Hopefully …

No again, the power supply is doing that. Motherboard is *not* the one that plays with power supply's voltage, the motherboard actually *requires* regulated voltages *from* the power supply which power supply is responsible for and must keep voltages within narrow range when current varies. Cheers, …

Wow those 16k x 4 are hard to find ! 64K in 64k x1, 8k x8 and 4 x 16K are a bit more common SRAM. I looked thru Digikey and Mouser and found nothing for 16k x 4. Wonder if 16k x 8 would work if in 24pin and same pinout.... though they are very expensive. Too bad the manual does not give some …

Looks nearly identical to the DECPC LPX as for Cache sockets, jumpers and two VLB slots (from what little I can see in the photo): https://th99.infania.net/m/C-D/34204.htm Needs 3 - 16k x 4 (64K) TAG chips. Without the TAG chips the board will not see/use the main cache chips. If it is the DECPC LPX …

Yup. All the jumpers were set as per the diagram on win3x, and the 386 processor and 387 jumper were both removed. I'll have to take a close look at the socket or the traces and buzz them all out some day, since it works just fine with a 386, it must be an issues between the 486 socket and the …
