JU-257A606PC oh my goddddd

OK so I had a JU-257A607P that apparently cant be modded, so I got hold of a JU-257A606PC

The instructions at http://amiga.serveftp.net/FloppyConversion.html

Must be the worst instructions in the history of man, this Anthony has a lot to answer for I have just demolished my drive. Such ambiguous instructions are insane, its the 21st Century what happened to pictures.

The only pictures I could find http://www.rabayjr.com/amiga_floppy_drives.htm

Is hilarious, you only get pictures of the drive.. erm, pictures of the modification would be a bit better! Argh!!

The jumper labelling is just stupid, my drive is demolished, and now I am pissed off.

I fully intended to put a PROPER guide up, im sure many more drives have been demolished than converted using these instructions

Yes, I myself alone have ruthlessly killed two drives the second one I got pretty close though and probably it's still somewhere here. I'll be really glad if you could make a clean guide if you figured out how to do this mod.

i might put pictures of mine up one day (dont ask when) . the mod only involves (from memory) cutting wire 2 and 34. connect wire2 (from controller end) to 37 drive end. This should at least make drive work (not for protected games) without touching the drive at all (much easier to mod cable) .

Then solder a wire from 34 controller end to a jumper point on the drive (ready signal). I did it by lowering the drive pcb and hooking the wire through the jumper hole un underside and just enough room to solder the wire upper side. no way to really damage drive unless really careless. I used the same panasonic JU drive that came with escom a1200s , i dont remember serial.

thinking about it I should nt that this would only work for pre escom amigas since the wire cut was done board level. although the principle would be the same i guess. a single long wire from mobo to the drive to provide ready signal.

Would involve taking miggy tower too bits and partly the mod to take pics which i dont fancy doing atm

Lightbulb

finaly i got pictures
my drive wasnt reading so took it apart for cleaning
while i was at it , i snapped some pics of the mod.
This is the 605p, the same drive that came with escom A1200.

The pics show joining wire 2 (mobo) and 34(drive).
and wire 34 (mobo) to SW1 on the floppy pcb for the ready signal.
