Re: Viewdata Service

This is a great service!

You remind me Dave, I had success in the past using 'ser2net' which is a Debian/Ubuntu standard. That was for inbound connections: ssh in through the firewall and routed to a Beeb.

Re: B-Em

That does sound promising! Is a Raspberry Pi up to the task of running this latest version with good performance? A Pi configured to boot directly into a full-screen emulator would be quite a thing, I think.

Re: The Beeb's (first) 32-bit second processor on TV

It's good that you were able to do that! I did use SPICE in the not too distant past to simulate the first few cycles in the life of a 6502, using the netlist from the visual6502 project. I was quite pleased with that, but it's an absurd thing to do, really one wants to be careful to simulate only a...

Re: The Beeb's (first) 32-bit second processor on TV

Oh, another thought: the 32016 appearing prominently in a 1987 feature about the genesis of ARM is a reminder that it would have been a good machine to run circuit simulations for the new CPU. The 32016 was not just a product, but a useful tool.

Yes, I've a feeling the Advertising Standards Authority were on the lookout in those days for adverts selling things which didn't exist. Didn't Sinclair get in trouble once or twice?

Cheers Rob! The most obvious guess for the third cheese wedge in the advert is the bigger faster 6502, and the second guess is the Z80 - I did wonder if the business user was supposed to be using Z80 software - but the "scientific" reference, and my own preference, steered me towards sugge...

The Beeb's (first) 32-bit second processor on TV

I think I might have found not one but two appearances of the 16032 (or 32016) second processor on TV... here, for example, in the middle of a segment about the genesis of ARM and the launch of Archimedes, in a compendium of 1987 Acorn clips: 16032-Acorn.png That "16032 Acorn" is part of a...

Re: Sideways RAM on the BBC Micro

(I think the logic analyser must connect to the Tube port in the case of a Beeb and the cartridge port in the case of a Master?? Or the 6502 in either case.)

(A discussion of assemblers, disassemblers, and toolkit ROMs, is probably worth a new thread, or a reinvigoration of an existing one?)

Re: Any short type-ins for unattended Beebs?

Ambitious! I've a feeling it overplots: I*2 should perhaps be I*4? In which case other things might perhaps be usefully rescaled? I reduced the iteration count too, to see more progress. But your version as presented is on the new updated SSD. A good test for PiTubeDirect perhaps!

I've never tried to do it, but a walking line with bouncing ends, Qix-style, should presumably not be _too_ difficult? I saw an Apple II doing that, once, so far back in the day that it might have been my first glimpse of a colour monitor. I was amazed!
