Hi all,

you may or may not remember the Phoenix in the showroom in this forum.

Unfortunately, the internal floppy has had its day. It is a modded DELL HD-Drive for the Amiga. If I connect it now the PAL chip gets hot.

It is this one (sorry German)

For whatever reason the ‘foil‘-cable had some burned marks. It doesn’t work anymore. Over the time I have collected two more of the external drives and one of the actual Floppy drives to see if I could exchange them for spare parts. In short no combination works.

So I would like to ask if I one of our gurus here could help with repairs. I already asked Hese (Amibay) and a Floppy-guru in A1k.org but they declined. Out of the three I‘d love top have one internal back working. An additional working external one would of course even be better.

The topping would be if one here could disassemble/read out the PAL on the adapter. The PAL has on it „PALC22V10-25PC“.
That would mean that the Amiga community would have a cheap way to get new HD-Floppies as the actual drives are still around...

Thanks,
McT

Oh man, this situation on your hands brings back some rough memories for me when I dealt with my own internal drive.

I can only speak from my own personal experience with the Sony drives that are available and technically made for the A500. They work very well and are reliable from what I've seen. The hardest part (and it was hard) was getting it perfectly aligned using the old bracket, which required custom holes to be drilled in that very solid metal. And lots and lots of adjustments, which was a total PITA.

Repairing a floppy drive would be some serious mad scientist work. Do none of your spare drives that you collected along the way work? Were they all "dead" when you got them, to use for parts?

Well I have a drive that works - a "Micronik HD Drive".
Might be similar to the "Amtrade real HD Drive".

Only issue is: its too big for my Phoenix.

So in total I have three actual drives wit one of them being NOS.

I have three of the PCBs with the respective PALs out of which one gets hot.

And I have the Micronik HD Drive that I hope could be modded as an alternative to fit the slimline floppy-drives.

The issue seems to be at least to some part the foil-like cables.
When the actual "wire" breaks the wire burns - thats how it looks like to me.

Help! :)
