Thanks a lot!
Did you manage to get a tape working? I couldn't format the tape on the unit I scanned and dumped.

Tape control and reading works fine on the existing media I got with the drive, but I've not tried any write commands yet as I need to get some fresh blank media, hopefully soon.

I'm actually quite curious to see if the tapes can be transferred to a modern using an old recording device that uses the same tape format, in order to see how the data is actually stored.

My drive isn't registering Write Protect status properly, so I can't do any write commands at the moment. Some hardware debugging required (and disassembly of the ROM for clues...)

Ah, yes it is. Details on the main Ikon Ultradrive thread.
Problem worked out by reference to the Philips mechanism technical manual, which I've uploaded here now too.

Would you mind uploading it again?
It seems you zipped a html file instead of the intended pdf file...

Hopefully fixed now. Stupid 7-zip, should have done it on my linux machine.
