US specification BBC Micro

Post by Lion » Thu Apr 04, 2019 11:21 pm

I have received what appears to be an un-UKified US specification BBC Micro. It was given to me as "not working", so I have not attempted to power it up. Is there anything I should test or do before plugging it in? (I am in the USA.)

Photos attached.

Change the psu capacitors perhaps?
Wonder what the machines history is? has it been in the wild in the USA all this time, or was it a greyhound job that has more recently been re exported.

I have one of those US keyboards that has never left England. It was probably a prototype!

Yeah, the main things to do before trying it are to replace C1, C2 (both X2 type) and C9.

Assuming there are no visible defects or damage, there are no other items that need to be replaced before testing.

However, after switching on, keep your hand near to the power switch just in case you need to switch off quickly.

If it works, that’s great. If not describe the symptoms and we will go from there.
