BBC Model B repair. Blank Boot screen, and it's not the RAM.

Very nice! Thank you. 😃

Nice vid. One comment if your TV supports it RGB to scart gives a far superior picture, than composite.

I think I only ever saw one BBC with the zif eprom socket installed on the keyboard, I was half-impressed and half "that looks too much like hard work"

"shoddily put together in the best way possible" great autobiography title

[@techdept]

I’m saving that for mine then. :)

there's something so nostalgic about the sound of a BBC keyboard.

[@techdept]

There really is. Just the beep from the speaker and I’m back in junior school.

@@techdept I don't know about your computer class, but in 1986 at my school the computer room, was filled with many different computers, not just the bbc, but the spectrum, c64, amstrad.. then within maybe 2 years they'd been replaced with pcs running dos, this was pre windows 3.11.. i have such nice memories of that computer room..

I have a similar issue showing only a cursor on screen but with a bbc+ model

Nice fix with the RAM enable issue there Jess... Calling the DC power cabling "shoddy" is a bit harsh. The designers have taken care and expense to route relatively high current capacity leads to multiple places on the board to ensure reliability (near the RAM for example).

[@techdept]

Yeah. I was a bit rude. The wiring did take me by surprise. I guess I’m more use to the speccy than the Beeb. But now I know the reason, so it’s a win for me. :)

I have almost the same problem,this might be the cure for mine,except mine does not show anything when I type but does run a program in the background if you run anything except no text on screen and a few cursors,but when I put jumper 25 south or removed they both show 16k ram so I think the ram banks are fine,it might be the same IC 39 problem that you shown here on my beep..

Nice video keep up the work. BBCs are great fun to work on never one the same fault. Well apart from the rifa caps.

[@techdept]

This is true. I’m getting a nice appreciation for the machine.

"Don't turn it on, take it apart!" - that's what Dave said... I'd at least use a dim bulb tester. If shit happens, it won't hit the fan. Watching you discombobulate and recombobulate the oldie... It fills me with determination. I love it that you don't hide the mistakes. No one is perfect and we really should get rid of the illusion that if you're not perfect, you shouldn't do stuff and show it. We're real people. We make mistakes and learn from them. Rome wasn't built in a day. Oh, Micro Men was nice! A bit too skewed on the BBC side, but I still liked it. And just look at Sophie Wilson! I had to try eating with DMM probes as chopsticks, here's the result: kzbin.infoZeXaZAbKi3g

[@techdept]

Thanks gorgeous. I screw up all the time, but I definitely learn from it. Micro men was great, and having Sofie in there made me very happy.

It's not bad for a machine that was designed in a week.
