First try is to clean the contacts with a rubber. All bar Romdisq (plug
(8-)# ) failed to use 'gold' plated connectors. I find that that
rescues most. It is rare to have other board problems - it is nothing
much more than an EPROM. I assume other ROMs work. As Sinclair used
sliced connectors, it is possible to crack them. I did that once when
something fell on a ROM.
