Re: Commodore PLC TIB DD-001 / Drive 2001

Oops, I just checked and there are no gerbers online. The schematics and pcb on github have been updated slightly from the one the group built. Feel free to try it. Sorry, I have no spare PCB's from the first run. If there is interest I could make another run. The first PCB is verified working, but there is some question regarding compatibility with different FDC chips. Either that, or some in the group have defective chips as not all of us were able to get it working (see my page for details).
Getting back to TIB, if I can get working schematics I'd be happy to make a PCB. I have all the parts already just waiting. The TIB uses PC-DOS format disks which is interesting, and the speed is supposedly very fast. I'd love to try it.

Ah, yes, that one!
So it's not on my todo list anymore :)
