I want to repair a non-working card and was hoping to find a schematic somewhere

I have never seen a copy of the schematics for about half of the Myarc cards. There is a Geneve schematic out there, as well as one for the HFDC (both on the Mainbyte site).


I built one a few years back for one variant of the Floppy controller (it is here on AtariAge), but I haven't seen schematics for the 32K/128K/256K/512K cards, the RS-232, or the Personality card. I've also not come across a schematic for the MPES-50.


Anyone having any of these out there? If yes, please post them. :)
