I gussed I destroyed the drive, the cable was connected backword.
fixing the cable didn't fix the problem, also noticed that the flat flex of both heads are cut right the way across.
I don't think it is possible to fix.
I think it is more appropriate to adapt a pc floppy or buy msx floppy of ebay instaed of trying to revive a dead one I have.
if you know of good sellers in ebay or ways to modify pc drives it will be appritiated.
thanks for all the help

I happen to have some TMS4416-15 DRAMS that I could use for ram expantion, they are 8kbyte rams, not the best but ok for now I guess.

The flat cable leads to floppy heads is hard to fix, so it's better to get a new drive. You might want to ask Bas - as I remember he had a lot of black drives for sale during the last MSX event.

None that I know of. I deal with Bas either personally, during the MSX events or by mail. I pay him with Paypal.

My piece of advice - get a GOTEK floppy emulator and the FlashFloppy firmware. This will be the ultimate best solution for this machine IMHO.

@ali6x944

Look, TMS4416-15 are totally useless in the RAM expansion!!! It's not the right size and not the right speed grade either.
Use TMS4464-12 or the equivalent.
