Hello! I'd forgotten about dumping all the ROMs, it seems like a different lifetime ago now! Glad to be of service, the retro community thrives on cooperation and it's always great to be part of preserving the history of the machines. Looking around the repository it's making me realise just how much 'bee stuff is out there that I had no idea about.
Ewan, I remember watching the video now you mention it; I wish I'd known at the time because I was only half an hour-ish away by car - I was workshop based then, in the next town over (Newmarket). It would've been nice to call in and say hi. You've answered the first question I was going to ask about troubleshooting, I'm guessing that the 'bee can't tolerate a single RAM chip failure so if one goes they won't boot at all. The RAM chips are all 6116 aren't they? I have spares of those so a quick poke with the scope might find some dead ones. I read on the forums last night that the 6545 is also prone to failure so that'a another thing to check.
Cheers!
