New guy

Postby FelisSapien » Sun Apr 15, 2018 6:44 pm

Hey gang,

Popping in to say hi... recently acquired a non-working BBC Micro Model B. A quick look suggests the major issue is with the power supply so I've ordered a cap kit. We'll see where that takes us. The unit otherwise looks clean enough but could do with a dose of retrobrite.

Really interested in this piece of history. Although BBC Micros were rolling into schools during my time there I pretty much missed out on using them completely. I spent more time in front of TRS-80s and the odd CBM PET. I didn't get particularly close to one outside of school either. I remember playing Chuckie Egg and Daredevil Dennis briefly but that was about it.

Once I've got my B up and running I'll look for a coding challenge. I've dabble with 6502 assembler on the 8-bit Atari's so that's probably my starting point.

Anyhoo, pleased to meet you all!

welcome Felis :)

if the X2 caps have blown, you can still use it without trouble, unless you are listening to analogue radio!
so, get it fired up & check all keys work, etc

Have Fun 8)

Welcome aboard. There is no doubt the BBC micro is a very significant piece of computing history and we like to keep them going. If yours turns out not to be as simple a problem as you think do post on the 8bit hardware forum here where there are plenty of knowledgeable people to help. And good luck with this as a hobby.

Welcome,
You might be interested in beebasm which can be found at our old site http://www.retrosoftware.co.uk/wiki/index.php?title=Main_Page, along with some other useful stuff.
For assembler and low level knowledge, The Advanced User Guide is great.
We also love to share our knowledge.
If you want to try out some beeb software, have a look at our archive http://bbcmicro.co.uk

Replacing the caps in the power supply did the trick. We have life!

Now to get my bearings... expect to see me popping up around the other areas of the board. Fairly early on I'm going to need to establish some method of loading/saving.

A quick question... is it normal for the internal speaker to quietly whine/whistle?

The beeb speaker often has background noise. I suspect one of the technical people on here can tell you how to sort it - I believe you need to solder a resistor somewhere.

For loading and saving I have just ordered two of these:-

viewtopic.php?f=8&t=12689&start=30
BBC model B 32k issue 4, 16k sideways RAM, Watford 12 ROM board, Retroclinic Datacentre + HDD, Viglen twin 40/80 5.25" discs, acorn cassette, Acorn 6502 coproc
BBC model B 32k issue 7, turboMMC, Opus Challenger 3 512k, Pi 3 coproc
BBC Master
