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.

Great progress!

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.

An excellent adventure - or meta-adventure perhaps.

Thanks JGH! I see André has also listed the per-manufacturer 6845 differences here.

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...

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...

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...

Ooh I like that - sunflower! (Basic 4 also has much faster trig, will help speed this up on a Master.)

The National Museum Of Computing (Bletchley Park) Earlier today after a few minutes typing! I typed in the programs! This is such a good result I thought it was worth a post elsewhere: here it is . (The weekly mos6502 posts are also collected here for those who don't want to follow on G+ - it's mos...

Nice touch with the link! There's a whole book about this program, and it's free:

Splendid!

I found some Ruby code here but probably you're already ahead with your Python code.

Sounds interesting!

Thanks ever so much, mildlydiverting, for keeping this kit in circulation, especially at such a difficult time for you.

That could be worth a bit of an investigation!

Welcome! An interesting idea. It certainly should be possible. This blog post https://www.retrocomputers.online/2013/11/lets-take-a-look-at-viewdata/ makes a successful connection to a particular viewdata service, via a Raspberry Pi and a serial port. That service is still live but I don't know if i...

And the Z80, which runs CP/M, where you can find Zorkish adventures. And Adventure on the 6809 running Flex.

That's brilliant! Thanks for doing the work and spreading the word. Type-ins for everyone!

(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?)

Thanks - pretty good! I see the program we've been calling SPHERE is here called WOOLBAL and is (c) Acornsoft.

If you ran that beastly random poke demo, it could cause trouble!

I'm hoping that you can NEW, then *EXEC a file, and then RUN the program.

(Thanks for the flowers too!)

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!

Most excellent! I've made up an ssd (and updated it) - I think I have everyone's contributions, and a couple more. Every file is a *EXEC type of thing, may need NEW and may need an appropriate MODE. (The Dragon fractal program is crudely adapted from a Rosetta code version in BBC Basic For Windows ,...

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!

Thanks for the screenshots! I feel a compendium SSD image might be needed, but there might be more ideas coming yet...

Thanks for all the contribs! (There's also a Rheolism (T*tris) for the Beeb: the section before this one.)

There are three modest-sized Lunar Landers, and much else besides, in this 1975 compendium:
