A typical NPN Power transistor, pdf here https://datasheet.octopart.com/2SC3420-Inchange-Semiconductor-datasheet-15978886.pdf I'd do the diode test with the multimeter to test the transistor, remove it if You have to. If the base is ever lower than the emitter then the transistor isn't even being …
Re: Need help repairing socket 5 PCI54PV motherboard

Check none of those evil Tantalum capacitors are shorted, they are well known for this. I have one on an XT motherboard that stopped the power supply from starting up. I'd measure the resistor pack, You never know, it may be ok.
Re: AMD K5 PR166 @133MHz
Posted on 2021-07-04, 12:47
I had no problems getting a K5 Pr133 running at 125mhz (83.3x1.5) on my Epox Super 7 motherboard. I have yet to try on another board as the max voltage the Epox could manage was 3.3v, so on another board that can provide 3.52v 133mhz is possible. It wouldn't do 133mhz on the Epox board.

I don't think anyone here will give You a definitive YES to that question. We can't see enough. It does look though as though that may be the case from looking at the top view. That point should be under M43 then and then go to just below where it says A1 next to M42. Maybe You can get a better look …

You can get the bios here ... http://www.vgamuseum.info/index.php/cards/ite … dent-tgui9440-1 Then you need an eprom programmer and a 27c256 chip or equivalent.
Re: [UN-SOLVED] Unable to install Drivers for Sound Blaster Live CT4780

The only thing out of the ordinary I see is what looks like a tumor growing out of the silvery looking part on the card. one of the capacitors was bent but bending it back up straight didn't fix the issue. That "silvery part" is the crystal oscillator and the "tumour" is just a solder blob that I …

Use this to uninstall the drivers https://www.majorgeeks.com/files/details/driver_cleaner_professional.html Then get an earlier driver for Your card, maybe 45.23 works? Don't get any idea Doom 3 will work acceptably on that system, it won't. Older games from 2001 and earlier should be ok. https:// …

Can't You create Dos install disks from images and install Dos from there that way. It was quite a long while ago I did this but seem to remember using 720k DS DD disks as XT's usually don't support 1.44mb floppies. You may be able to format a 1.44 as a 720. Another thought might be to see if You …

Re: A noob and XT-CF Lite woes
Posted on 2021-02-26, 13:50
Hmmm, maybe my "help" was bogus. I have been using my cf-lite that I made myself in an XT machine lately and had similar issues. Dos actually sees the 2gb partition as non-dos so maybe imaging isn't going to work. How about just formatting it as FAT only, not fat32. Then just simply copy the files …

Some of the parts I got recently. The Audigy SB0240 was supposed to be a full SB0350 as pictured on ebay, so got a refund for that and have kept the card. The Midiman and Aztech 4dwave will be interesting to play around with, especially with the wavetable headers as well.

I've been messing about with my Epox EP-MVP3G5 with a AMD K5 PR133 in it which it actually doesn't support I suspect due to the fact that 3.5v is not available. Anyway it works ok at 83x1.5 = 125mhz at 3.3v. I have been trying to play a game I bought in 1994 that I never played - TFX, but it keeps …
