This very nice Elite 4/75cx: DSC_3047.JPG But it needs some work. This is on an external monitor, probably VRAM issues. DSC_3048.JPG If repairs are unsuccessful, I'm gonna need this Upgrade Adapter, since I already own a LTE Lite Desktop Expansion Base... That's gonna be a tough search. Then I can …

As a kid (and still am) I collected CPU's and glued them on a bulletin board, the kind with push pins to be precise. Now I am restoring one of them, I use the Overdrive 'socket' as a mold.

Does your friend or an acquaintance happen to have an oscilloscope? Odds are the crystal is fine.

Do you have any other card at hand? I assume not, otherwise I think you would have tried. Is your CPU cache working? How much and how is it set up? If the issue is the only one, I guess the ET4000 doesn't play nice with that particular part of the game. If you are looking for a replacement, I would …

I just installed a Matrox G450 in the dual themed rig. It's more fitting than the Geforce256 which was overkill anyway... The G450 still is, but I wanted some good 2D quality and DualHead. Filename DSC_2991.JPG File size 1.77 MiB Views 1375 views

I'm still following this thread. I feel sorry for the P8+P9 connectors haha, that's some serious power. In terms of current and performance. Who needs EPS-, P4-, AUX-, PCIe 4+4 connectors... ;) And yes, hard choices have to be made when picking hardware. I'm in the same boat when choosing a sound …

Investigating which type of DX4 an acquired system contains. Happy days. :) DSC_2980.JPG L2 cache seems bad, stuck at Updating ESCD. When the L2 cache is disabled, it boots. So I ordered some new 15ns cache chips and while I am at it, it is going to be 512kB total. I hope the TAG chip is okay, that …

That's where proper grounding comes in, an earth leakage circuit breaker, (the green/yellow wire). But without grounding, hopefully, somewhere a fuse (box) should trigger.

I've been working on this double speed Aztech CD-ROM drive. It refuses to spin a disc. But the motor spins for a brieve moment when powering on, even when powering off it spins a little. I don't think it's worth to replace the whole CDM-12.4 unit... I think the problem lies at the main PCB. Cause …

Easy fix for this Voodoo2, and a reminder to pay good attention to the chips' legs. At the moment they short, the card came up in the BIOS device list as Unknown PCI card and even got an IRQ assigned. As some of you already know, Voodoo (2) cards don't need an IRQ to work. Before and after pics …
