Thanks Derek, I did a visual inspection but will do a continuity test with a multimeter.

To reflash the Superhermes rom code, will be hard due the code not being available.
yeah, and the PIC version on SuperHermes has an EPROM so it's program-once. If the PIC turns out to be faulty, the only option is to get a new one but as you said: since the source is not available, it would need to come from Tony. I don't know what the lifetime of on-chip EPROMs is supposed to be but 27 years is a long time

I can ask Tony if he can supply me with the code and how to ipdate the flash rom.
Thank you Derek, that's extremely kind of you. Let's hope it's not the PIC but something else. I will test the continuity from pins to the PIC socket and also verify that the oscillator works. But, it would be really good to have a source of replacement PICs going forward!
