Hello everyone. My apologies for the double post - I wasn?t certain that I had posted correctly as it was before I had been sent an approval message. I?m enjoying your threads but honestly a lot of it goes over my head - I?m primarily interested in repairing early digital synthesisers, samplers and effects units for audio production. Anyhow, I just wanted to introduce myself and say that i?m enjoying (trying to) follow/ing your early computing banter. Cheers, Nigel
