Re: ICL OPD
JobDone has managed to fix the C1 floppy interface's ROM so that it now formats a drive that MSDOS and the Atari ST can read and write to. Windows 10 barfs on it, however. I'll be doing some more verification before we publish it. Technical bit: The ROM blindly writes a string held in the ROM to the...

Re: ICL OPD
It looks like the disk image I was using to test was corrupted. This may have been due to the Gotek's FlashFloppy version being old or because I had pin 34 set to change rather than ready. It certainly writes more quickly now. Anyway, the converted version now mounts in DOSBox but something is not r...

Re: ICL OPD
Exxos has some in stock.
The PCB itself isn't documented really as it was only for my consumption as a prototype board, hence lack of info it the Gerber files.

Re: ICL OPD
No-one has usable OPD schematics let alone CAD files.

Re: ICL OPD
Here's the ROM image. Thanks for sharing that. I can't find at a glace what the electrolytic capacitor values should be or the details of the resistor network. The chips and resistors are clearly visible. I've ordered some PCBs and am looking forward to setting it up with the OPD. Pr0f, I'm sure an...

Re: ICL OPD
Here's the program. From what I can see it should have the correct parameters.

Re: ICL OPD
I've written a program to change the C1 floppy boot parameter block to an MSDOS one. Looks like the C1's FAT12 isn't quite as it should be: [root@nowhere opd]# mount -t msdos /dev/loop0 /mnt [root@nowhere opd]# ls /mnt ls: cannot access '/mnt/myfile.doc': No such file or directory dr240110.181* dr24...

Re: ICL OPD
It's fixed at 720K, as per the Apricot floppy interface.
