Damn. Feels like it was sort of close, but also a possibly endless 'just one more thing'. Blame hidden battery damage, that's what did for the one I had.

Nice, so does that mean you've got two probably broken 187hp and one working? I'm hoping that's the one I sent... That .exe is a self-extracting zip, looks like you can just unzip it. It includes a few files, including a couple of files that can be just be put on a 720kb floppy which can then be …

Might just be flux residue, but there's a lot of brown muck around one of the legs of the LED by IC55 / CLU01 near the VGA port. I'm not sure from the photo if the LED case looks slightly melted or not. 9V vs 5V to 3.3V through a linear regulator means about 3.4 times the power being burnt in the …

Did you replace all the big capacitors on the board (~470uF and bigger), particularly any near the AGP slot? For example, there's a picture of a K7T Pro2 here: https://theretroweb.com/motherboards/s/msi-ms-6330-ver-1.0a where you can see someone has replaced 3 big caps up by the CPU, but not the two …

Re: GeForce4 4200 ti with a Busted Memory Leg - Repairable?
Posted on 2024-03-14, 10:54
Looking at the datasheet for the K4D261638E (think that's the right part?) then the broken leg is 54 - DQ8. Leg to the left (53) is N/C and leg to the right (55) is Vddq. So I think there's a good chance the chip will be ok, even if the PCB pad for leg 54 has been shorted to leg 53. Datasheet just …
Re: Strange socket 7 USB header issue
Posted on 2024-03-11, 17:14
I think some boards turn off power to USB ports when in suspend mode, so they have a FET between the PSU 5V and the USB 5V. Could be something like that causing a bit of resistance on that 5V line, so when anything tries to draw an current the voltage drops. If there is a FET that switches the power …

If no one has any information, any chance you could use a multimeter to check which pins on the ISA slots go to the power connector? e.g. hold one probe on B3, check for continuity to each of the 12 pins and any that measure short are +5. I think B1 is Ground, B5 is -5V, B7 is -12V and B9 is +12V. …

Not sure if it's a good idea to have different 5V supplies. If you haven't already then it might be worth making sure that their grounds are connected.
Re: Keyboard + mouse connectors problem part 2 :)
Posted on 2024-03-02, 19:06
There's a difference between a pin being directly connected/shorted to +5, or pulled up to +5 via a resistor. A pull up resistor means that if the pin isn't being actively driven by the chip then it'll measure at +5V, but the chip can drive the pin to Gnd. For example, on the PS/2 connector, one pin …

Haven't quite worked it out in my head, but could you just get a 40 pin male IDC connector and crimp it on to an existing cable? Or get a whole extension cable like https://www.ebay.co.uk/itm/115877431226 ?

From the photos looks like a couple of areas of maybe something sticky, and a few bits of debris near tracks near one of the connectors on the motherboard. Could be worth cleaning up and checking for any broken/shorted tracks.

KA7 layout is a bit different, but there's a 10k pull up/down in a nearby location.
Re: KT7A missing IC
Posted on 2023-11-05, 23:29
I've only got the KA7, so even though the RAM voltage supply was the same, I expect the clocking will be different. I'll try and have a look mid-week. I still suspect something is over-heating, but that's just a guess. I don't know, but are the PS/2 ports driven from the Southbridge?

You'll need to work out a couple of things. Firstly on your cable which pin on the rectangular connector (IDC connector) goes to which pin on the Dsub connector. Easiest way to do that is probably to take the back off the dsub end of the cable so you can see which strand of the cable goes to which …
