    i'm looking to buy two or four identical SIPP modules, 256K (set of four) or 1M (set of two or four) regardless, as long as they're cheap and located in the EU. I need them to test a 286 board. Cheers

    Advantech PCA-6003 single board computer won't boot

    Last year I picked up a PCA-6003 single board computer from the recyclers along with the PCA-6108P4-C base board. I found that two 1000uF 10V capacitors on the card itself were bad so I replaced them. However, when I plug in an ATX power supply, the system turns on as soon as the PSU on/off...

    Toshiba Satellite 2100CDS LCD upgrade

    Hi all, I picked up a nice Toshiba Satellite 2100CDS laptop about a year ago at the flea market. It works but a horrible DSTN screen. I know Toshiba also sold laptops with TFT screens marked CDT so the question is, can I just swap out the screens between models? Mine has a 400 MHz AMD K6-2, a...

    5.25" floppy cable for XT build

    In my XT the floppy controller is on the I/O card and it's using an edge connector. How do I go about making my own cable? I have lots of normal floppy cables lying around so I can cannibalise one. The floppy controller is a UM8272A.

    XT clone motherboard - blown up capacitor + questions

    After about 20 years of not using it, I picked up my parent's XT and brought it home. As soon as I turned it on, one of the orange caps near the keyboard connector just blew up. It's marked C8 and lies between the keyboard connector and JP4 2-pin connector. The only markings on the caps C6-C9...

    I recovered this motherboard from the dumpster. After messing about with jumpers I got it to POST but it doesn't do a RAM count and gets stuck in a reset loop. I'm also unable to enter BIOS. Somebody pointed out that the keyboard controller is missing. Can somebody confirm that for a fact...
