Alas, the reconditioned BBC Master Turbo I bought towards the beginning of last year is now sickly. What was a stroll down memory lane has become a project.
When I switch on the machine, I get the Acorn MOS message and (usually) the DFS one, but then only a flashing underline cursor. Once or twice I’ve seen more (‘not a language’ or something like that), but only rarely.
Initial research and calls for help suggest that I should reseat all socketed ICs. But there are only two chips on the motherboard that are socketed – I’m assuming they’re the two 6522 VIAs. And my first attempt to remove one ended up with the whole socket coming away, leaving its metal contacts in place. Eek!
So I reckon I’m going to be doing some desoldering and soldering in a new socket. That’s not something I’m looking forward to, to be honest.
If, as is possible, it’s a duff RAM chip, then I may be forced to give up for the immediate future.
This is a fairly low-priority problem for me – I have too much else on my plate. But I plan to do more tinkering and research, starting with posting to the Stardot forum – the fount of all wisdom in matters relating to the Beeb.
I will update this post as things progress (or not).
