🇬🇧 BBC Master Compact: Part 3 (Motherboard Fault) [TCE

[@larrywilliams8010]

Nice sleuthing. I was thinking it had to be a broken joint or trace and the case was flexing the board.

What a lovely looking machine - Never seen one of those before. I'm from, and in, the UK. I don't think we had them here? We did have the BBC Master System, but it didn't look like that. 🙂

Oh, it was definitely released in the UK! I'm actually surprised I found this one in Australia. It just wasn't very popular from what I understand ... 3½" drive & ADFS meant all of the existing DFS software on 5¼" disk was out of reach (although trivial to sort out today), and useful ports like cartridge, User, 1MHz, Tube and cassette were also removed, with some functionality provided by an expansion edge connector. Interestingly, Olivetti did release a version called the Olivetti Prodest PC 128 S.

Finaly - you fixed it!!! I did trust you, but just in case there was the backup plan with the green pad. 🤣

[@Brfff]

The green pad would've fixed it as well I think because those pins wouldn't have been resting on the stand-off directly!

[@MrWaalkman]

Well done! And WTF was the case and board designers thinking when they didn't cooperate and make a place for the board to sit in the case that wouldn't push against the standoff? Just plain dumb. You did solder both joints didn't you? You were speaking in the singular, but there were two damaged pads (actually three, but that is a bent pin and probably not a concern as of yet).

Is this what the acorn electron should have been ? Will it play chuckie egg…

[@Brfff]

It should do ... the Master is just a better Model B ... ? More RAM and other tweaks. I'm planning to add a DFS ROM (although you can also load it from the Welcome disk into sideways RAM) so I can access all the DFS disk images
