I'm working with a gentleman who's trying to get his PEB up and running. He just acquired a Myarc FDC card with 80-track upgrade. I'm trying to build a floppy cable for him, but it seems his Flex card went out before he was able to even get started. He also has a TI FDC, and I have no reason to believe that either of the FDC's are the problem.
I did some initial trouble-shooting with him, and it seems like the Flex is locking up his system, with or without other cards in the PEB. I suspect the 74LS245's, but doesn't really matter because he doesn't have anyway to do the repair (if it is the flex).
I have a Flex card I can offer him, possible trade (I can repair it).
However, I don't have a Myarc 80-track ROM set. I do have a Myarc FDC. Is there a known good set of 80-track ROM's for it, so I can test his scenario on my system? Last place I knew to get those was from Richard Bell, but I don't remember if he's on here or still providing. (My apologies if you here and I have forgotten your screen name).
And possibly the documentation as to what the new ROM's provide. I gather it's a more elegant 80-track solution than the TI one.
In addition, Is anyone else helping someone with this problem? Speak up if so... Trying to communicate via the other service is driving me f'ing insane.
