Great!

Is it the difference that DIR is more common with file systems that can handle subdirectories as well and CAT does not?

Can give the layout files in Eagle 3.55 format or as PDF. And the ROM image too. Anything you need to build your own mageco.

Welcome Thomas.
Am I allowed to advise a German forum?

It is interesting that the mageco IF works without any controller chip. Only done with LS logic.
As I had tested it worked very stable and not even slow.

Hi Didier,
good to know you're here

Email address for Didier? I have. But he is not with electronics.
If somebody could help me to get the IF running. I would send my PCBs for further testing. Also have the designs in Eagle here.

The schematic on XavSnap was drawn by me.
Now I have the name: Didier Pous from Bordeaux. Anybody know him?

I had this interesting interface 10 years ago here for repair.
It was from somebody in France, (Bordeaux ?) but I don't remember the name.
I made a copy of the PCB, it was working so far and I can read the discs, but it doesn't write correctly.

Link is down.
I have this as a good copy. May be scanned much quicker. Will do it the next days.

Then I was some years away from that and did other electronics as the ZX Team ...
