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.
Regards
Rob

My jaw dropped when I saw this:
https://www.ebay.co.uk/itm/223201002247?ul_noapp=true
It looks nice externally, and it has the pedestal, which is nice, but the
seller has not even give the spec or posted pics of the innards and it is
"untested". 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.

OK, not really a Rainbow, but that's the term to search for if you want to buy one
cheap. This one is $99.
