I think breadboarding sounds like a good idea. Is this something you would tackle? I only ask because I don't have a breadboard, nor a drive (I just ordered one though, but no knowing if it'll be functional on arrival), nor have I had any experience in breadboarding. If the idea is to make sure the ...

I'm all for making it easier for back up files for preservation, so I think your idea could be a good one. Presently I'm trying to make working backups of some old 1978 Apple II cassettes so I understand how difficult these things can be. Some of these old tapes seem too far gone for any amount of a...

Thanks to Steve Gray who had a look at my alpha 0.1 files, he was able to play around with the layout and get it to auto route. I took the file Steve altered and then did the following: - Manually routed GND trace with .5 thickness trace (presently only the GND is routed, all the rest can be auto ro...

Just another quick update. I found this site: http://home.iae.nl/users/pb0aia/cm/8-525.html It covers converting devices that use 8" drives to 3.5" drives. As far as I can tell, a Shugart 50 pin connector carries basically the same signals as a Shugart 34 pin connector (albeit with different pin loc...

I hadn't even realize that they were not the same. The schematic is presently drawn for the Shugart drive, and certainly we also need compatibility with PC drive too. After a little research, it seems that the following pins are different between Shugart and PC drives: SHUGART DRIVE 2 = /DCD - Disk ...

Hi Dave, Thanks for the reply. Yes, I was pleasantly surprised how easy Eagle was to learn. Obviously I only know the basic stuff it present, but that was enough to put this board (mostly) together. Strangely enough I could not find a 74LS38 in the parts library, thats why I chose the 74LS37 thinkin...

With some proding from dave, I gave myself a crash course in Cadsoft's Eagle software. I was surprised how simple it was to learn the basics. I have completed a first pass of the floppy data seperator and motor control card schematic. I'm still learning so please forgive me as I think it's a little ...

As promised here is the first pass at a schematic for the floppy adaptor: schematic.jpg I told you it was going too be rough. Some questions still remain: - Why are there two motor control switches? - Some component names can't be read because the text in the PEEK65 article is too distorted/small. -...

Hi Steve, If I could draw up a rough (very rough hand drawn) schematic will all the right connections, switches and jumpers, would you be able to transfer this to Eagle and layout a board design that we could get fabricated? Unfortunately thats all I can offer considering my lack of PCB layout skill...

Thanks Dave...yet again you ROCK! As I have no skill in any PCB layout software like CadSoft Eagle, I have drawn it by hand using Adobe Illustrator. Basically it's a fairly accurate copy of the original, however I agree with you, if we were going to make a small batch then it would be a great idea t...
