Re: RISCPC 600 motherboard for sale/swap

Not sure if Bitstik ever came with an actual rom. Mine (fully boxed with manual etc, so presumably as sold) came with a labelled eprom. IIRC my prestel adapter also came with a labelled eprom. Perhaps Acorn only made real roms for the stuff they expected to sell a reasonable amount of? Happy to send...

Re: Worth Taking a Look At

The 80x25 definitely is a System card. Don’t know enough about the eurobeeb to say if it’s compatible, but it may work in an atom - the expansion connector is the same, and System Econet and DOS boards certainly worked.

I’m trying to move my software archive between machines (some HostFS, some ADFS). Previous attempts have led to corrupted file attributes for random files.

Re: BBC model b turns off

Have you checked the voltages on the auxiliary power connector, ie does it produce 12V? I’ve had a PSU where Q4 died. Despite appearances and labelling, it isn’t a transistor but some sort of comparator to regulate the 5V line. The symptom was that the 5V line was dead but 12V was fine. For the reco...

However, there’s no cursor and the keyboard’s dead. Swapping the two 6526 CIA chips changed the problem ...

Re: Windows 10 (and 8) and Laptops

Part of the problem is that both CPUs are pretty dire, with woeful Passmark scores. The P360 is low-end, but the 4355M is even lower. My old laptop is an 8 year old I5-430M (also HP), so hardly high-end or expensive, even at the time of manufacture. But even that CPU scores higher than those two. Wi...

Re: Trying to restore an ABC310

Good suggestion, but I doubt it’d be strong enough.
These things are sheet steel with pretty industrial hinges/clips. Unfortunately, they seem to be less than precision engineered, so take quite a lot of force to open/close and even more force (I worry about using a weak screwdriver) to clip shut.

One of my (alleged) Cambridge Workstations came from inside Acorn. During it’s life, it’s had its 32016 board removed, along with the hinged aluminium carrier that the copro board usually sits on. What makes me suspect that it wasn’t originally an ACW is that it also has the Acorn mouse board fitted...

You may have hit on the reason why it was designed but never launched as a beeb in 1983. The 1985 Beebug review of the 128k upgrade claimed that the connector was never intended for sideways ram. It was originally there to take a different type of main ram should there be supply issues with the usua...

Re: I've wondered this for thirty years...

Agreed. So the bigger question is why it wasn’t rolled out as the Model C in 1983/4, when it would have been a much bigger hit? As it was, the July launch reviews all asked the same question. And when the Master came out the following February, the people who’d bought a B+ were foaming at the mouth....

Not sure if this counts as sage advice or just an example of luck triumphing over stupidity... Whenever I re-cap a PSU, I always test it off load.
