also rather nice surprise with this "mystery" PC, I didn't really know what I was getting but I assumed 286 and I wanted the EGA card anyways... assumed correctly, and a nice one at that... in need of immediate battery amputation, there's quite nasty corrosion on the keyboard connector but the …

That's certainly an improvement ! You'll want to do a needle test on the chips. Take a needle and skate it strongly across the pins to find any bad solders. Chances are some pin is not connecting right and causes the problem. Are the missing sounds always the same and are any sounds outright wrong …

Top one is a 7805 (ground in the middle) and lower one is a 7905 (ground at a side). Thanks Tiido! Sounds reasonable as the 7905 on the bottom was the one that was still installed as I got the card. So I will order a 7805 and test... IMG_0185r.jpg Tiido...! :-) You are the master! Many thanks for …

Arrived! nice! wavetable boards are so elusive, I spotted one in a scrap box on ebay once, but apparently I wasn't alone, it ended up far over €100... and it wasn't even a very special one. I'll stick to my external midi modules for now ^^ wavetable boards are just too expensive, also limited to …

I have been looking for this for weeks! Finally found a seller. Orchid Tiny Turbo 286 - XT class accelerator. It is an ISA card with a mini 286 motherboard. It also has a socket for an 8088, so you can toggle between the two processors with a switch. Can't wait to put this in my turbo XT :D Very …

Asked the seller to send me one of these cards for 15€ ... or 20€ with slot bracket. Unfortunately without bracket, but he agreed. Which card? ;-) s-l1600 (1).jpg Where is this listing at? I'd definitely give that for what looks to be an 8-bit sound card in the bottom left. My XT is eerily silent. …

As you seem to be motivated to do some testing: Remove one IC from each bank and each from a different position. You will see a different pattern for each bank in testext and will be able to distinguish banks 1-5 during your tests.

If I switched it into a position where it would interfere with other memory, wouldn't it just not appear or cause memory errors? Good question...I would expect memory errors? Just for kicks, I put all of the switches for "Bank 1" off. Result: Here you see my table is not that bad. You moved bank 1 …

Discovered these in 10 kg scrap lot and asked the seller to send them to me for 20€. Think its my 10th 1350B but I like these cards. Still have the one I bought around 1992 in its original packaging. This SMC network card is also my favorite one, all connectors available and configuration via …

How about to continue with 111111 and to move it towards the end? That reduces the risk that the bank you have moved interferes with already existing RAM...think this is the reason that there is no change.
