I once took a plane ride back to Raleigh from a computer show in Boston in the 90's with one of the guys that built the 5150 board at IBM. They used off-the-shelf parts, just trying to lash something together fast that worked. No one else at IBM took the PC "revolution" seriously when it was...
OS/2 was only ever delivered on 1.44MB disks (and CDs); the post-4.0 convenience packs were delivered via bootable CD images. There were definitely some X-series IBM machines delivered with 2.88-capable floppy drives, though.
I wonder if something as simple as cleaning the drive heads would get the drives going again? It's unusual for floppy mechanisms to fail outright, so I'd suspect fouled heads and failing media before suspecting the drives themselves.
I didn't find any disk images where I expected on bitsavers...
I've got a couple of 8" disk boxes here that are from IBM, and have "AIM" on the cover - it's not much good googling that little information, so I thought I'd give it a try here. Does anyone recognize what this program might have been? (They contained unrelated disks, so they're no help!)
I was helping someone prepare for VFC East this year, and long story short - I ended up with five Bernoulli 20MB 8" floppy/cartridge drives. One of the five works wonderfully; the rest refuse to load the media after inspecting it. Given that these drives came shipped with a cleaning cartridge...
I finally assembled all the pieces I needed to get an 8" Shugart talking to my iMac. It includes DBit's FDADAP and FDDC, and Device Side Data's FC5025 adapter. What's that you say? Video or it didn't happen? Fair enough:
Edit: I found what I was looking for in the manuals that Dave Dunfield has made available: http://www.classiccmp.org/dunfield/kyocera/index.htm
Specifically, http://www.classiccmp.org/dunfield/kyocera/portdisk.pdf and http://www.classiccmp.org/dunfield/kyocera/disksoft.pdf.
I've got a few disks...
I've taken delivery of a QX-10 computer and keyboard. No monitor, though. I have lots of nice references to the pinout, such as this:

In case there are sarasaurs out there that don't read the apple3 mailing list or the c.s.a2 usenet group... there's a new driver and utilities disk available for CFFA revision 1 and 2 cards. See:

Does anyone have an adapter pinout to adapt an Apple III to a Disk II? There has been a little discussion and links here:
http://68kmla.net/forums/viewtopic.php?f=6&t=11136
but nothing definitive. I now have the pinout for a Disk III to Disk III+ (IDC 26 to DB-25) adapter, so I'm closer - but...
My Apple III had an unfortunate accident today. Dropped a IIgs keyboard on top of the III, and broke off the Alpha Lock key. :mad:
The nylon post snapped in half. What's the best glue to use on nylon? The break isn't clean enough for cyanoacrylate (super glue), I don't think. And I'm...
I recently adopted a Franklin Ace 1200 whose keyboard had failed entirely. Early Franklins used the typical Keytronic foil-over-foam capacitive design, so I set out to fix it with inspiration from Geoff Harrison:

I read several sites that had recipes for the...
