Sadly this is on the wrong side of the pond. I would like to repair the one I have in any case.
In fact, while I think I know the pinout of the F11 chips from a KDF11-A printset, can anyone confirm that pin 23 of the DIL package is the RESET signal? If that is correct then it is oscillating and resetting the machine constantly. I am trying to trace the source, but it seems to go through quite a few chips and I haven’t yet traced its source.

At that price I would expect a bit more information.. As it happens, I am trying to fix my 350 at the moment. Untested Pro 350's are like US$150-US$250 range on ebay typically. https://www.ebay.com/itm/VINTAGE-DIGITAL-EQUIPMENT-CORP-DEC-RAINBOW-PC350-I-COMPUTER-FLOPPY-DISK/332562279306?epid=583415379 <https://www.ebay.com/itm/VINTAGE-DIGITAL-EQUIPMENT-CORP-DEC-RAINBOW-PC350-I-COMPUTER-FLOPPY-DISK/332562279306?epid=583415379&hash=item4d6e41ab8a:g:qR0AAOSw9NBafMjq:sc:FedExHomeDelivery!80602!US!-1:rk:1:pf:1&frcectupt=true> &hash=item4d6e41ab8a:g:qR0AAOSw9NBafMjq:sc:FedExHomeDelivery!80602!US!-1:rk:1:pf:1&frcectupt=true OK, not really a Rainbow, but that's the term to search for if you want to buy one cheap. This one is $99. Warner
