Re: BBC Micro - Erratic Behaviour

Welcome,
we will try to help, and a quick scan around similar recent threads should give you an idea of what sort of questions, answers and experiments you are probably in for.

Is that beeb a bit shy, or is it ready to be pulled out and used at a moments notice ;)

Re: what should i write next?

Wasn't someone looking for ideas to "improve" Thrust?
It could be done using vertical rupture for vertical scrolling and software (Scramble) scrolling for horizontal.
I don't think that it is one for me though, although there should be a smooth multi-way scroller on the beeb.

Re: Preemptive maintenance

User VIA handles User Port (SPI/MMC) + other stuff. System VIA handles Keyboard inc LEDs + lots of other stuff. RAM faults in the lower 16K tend to crash the beeb, often with no screen corruption - you can try 16K mode in MODE 4, 5 or 6. I don't know if UV can discolour a beeb, but heat can so it do...

Welcome, Check the heatsink on the video ula if yours needs one. I can't think of any other preventative maintenance. If you are using a TV, an rgb to scart is a great option.

Re: BBC Model B faults

That would suggest that the sa5050 isn't reading the same value as the CPU, at least if the character is copyable.
I'm not sure which lines go where, but hopefully it might give someone else an idea.

Re: Hello. New forum user. BBC master

I would consider swapping one of the drives for a gotek with the opensource FlashFloppy firmware (they usually come in 3.5" cases).
You would still have a real floppy, but it would be much easier to backup your old discs and add new ones.

Re: Hello. New forum user. BBC master

The caps shouldn't kill it, but they will "stink it up"!
If one of your discs had mould on it, it is probably on the head causing problems and spreading to the other discs!
There are plenty of threads on here about both and loads on mouldy floppies on the general web.

Welcome,
Sorry, don't think I can help with the adventure, but you can also take a look around bbcmicro.co.UK a sister site with a a great archive or the older stairway to hell.

I only remembered yesterday that either philosophers quest or Sphinx adventure have a dragon (or maybe a Sphinx) :lol:

Welcome,
While you are getting things working, you can take a trip down memory lane at bbcmicro.co.uk and maybe have a look at the new hardware available for your "beeb". You might like to start with a look at GOTEKs as you have a working disc controller.

Re: Newbie questions: Programming tools and graphics

beebasm has a sample program that I think prints dots on a rotating sphere, by plotting single dots in MODE 1, or a reshaped version of it.
You might also find some useful stuff on http://www.retrosoftware.co.uk which used to be the programming section of *.

He has a huge talent and I wouldn't have made the games I have without his help and inspiration.
