I only regret selling some nice retrostuff to a complete moronic, doublefaced and lunatic person locally. It's a screw-up because I sold my gear at a nice price to someone not worth it. I would feel much better if I killed it with a bad PSU or something.

Todays report - thanks again for all the suggestions above - I still cannot get this going LOL - I left the drive powered for ~2hrs , it's noise changed a bit but it did not help - I ended up setting up a 386DX40 test machine because old legacy 1.12 text-mode Seatools did not work on the 286 and …

Does it really worth to build a lptdac device that sounds "perfect" ? I can understand that one might want to create a version with the cleanest sound but these things are supposed to be cheap, simple and have a unique output. If you take that all away then they lose their magic IMHO Personally I'd …

thanks for the suggestions, the motherboard does not have onboard IDE - it's a 286 board. I will post a BIOS shot tomorrow - the parameters on the BIOS are the same as those on the handwritten sticker. I can boot from floppy but I remember I tried booting with the XT-IDE CF adapter: I got the same …

Well, I don't really want to reformat the drive - I just want to retrieve it's data if possible. I don't see me using it ever beyond that btw LOL I had another look on the drive/controller and made a boot video as well - this time with a 286. - you cannot install the cables the wrong way since they …

- BIOS is set to have HDDs , just like the geometry on the label. I found a datasheet on the net and the geometry looks correct - cables are OK but I have tried them the other way around as well - I have not looked at a pattern, will check it and report back - I get the spin up sound and then some …

Hiya! I recently got a Huyndai Super-386C PC and it came with a ST-251-1 HDD + WD controller - both are items that the PC was sold with, not something extra. The drive spins but I get this error on boot: http://i.imgur.com/qXOwD3Gl.jpg What could it be? Stuck heads? Can I open it and try to move …

exactly, you will need the MPU-IPC-T interface card - no other simple interface will work with your breakout box https://commons.wikimedia.org/wiki/File:Roland_mpu-ipc-t.jpg

Tried to make some recordings with my Disney Sound Source but I totally forgot it does not work with covox/lptdac stuff... anyone knows a game (preferably) that supports both options so a comparison can be made?
