Re: Wish: MAVIS computer recreation in Mode 7

More to come, probably, but not imminently. Probably. Hope so! Would it be possible to copy these tapes using the HP kit. Tape to tape style? I'm giving a talk for the GAconf Europe event in April on MAVIS. I'll let people know that this sort of stuff is going on in the chat. This might be of inter...

Re: MAPE Micro-Scope Magazine

Once I've finished part one of my Accessible Gaming Museum, I'll be fast onto the BBC Micro era, and plan to get a load of my BBC Micro/educational resources scanned which I'll happily share. I'll be linking to your page for certain as extra resources. Meanwhile, have you seen this Blue File No.9? V...

Re: MAPE Micro-Scope Magazine

Great work, John. Really enjoyed having a look through those editions of MAPE Microscope. Would be great to get those missing editions that cover the time when the BBC Micro was released, Information Technology Year (1982), and so on. I have a couple of large books that may be of interest if I can g...

Re: Wish: MAVIS computer recreation in Mode 7

Re: Wish: MAVIS computer recreation in Mode 7

The tapes are sealed unfortunately. I've started to create a tape player for these tapes. Very early indications suggests that there is a good chance of recovering data of the tapes. A long way to go still. So not standard mini, nor micro-cassettes? I wonder where they came from originally. Good lu...

Re: Wish: MAVIS computer recreation in Mode 7

I'm going to have to think again. The tapes are a different size. If I understand correctly, MAVIS used mini-cassettes, the size inbetween the larger and much more common compact-cassettes, and the smaller mico-cassette most often used for dictating machines. https://i1.wp.com/www.manchestervideo.c...

Re: Wish: MAVIS computer recreation in Mode 7

Interesting to read about the machine, Barrie, thanks for putting the materials together. I note the Teletext solution at that time was a two-chip solution. I might guess that the Z80 clock frequency has something to do with the speed of the teletext subsystem. But it would only be a guess. Dominic...

Neat system, and a real shame it was lost. The 2.308 MHz Z80 is a frequency I haven't seen before. Wonder if it was a standard design pressed into service? The project dodged a bullet not using bubble memory, though — great in theory, unreliable in practice. Just a year or ten ahead of its time I f...

Very impressive. On my emulator and laptop I have to press SHIFT ; to go up, which is faffy.

Feels good though, compared to the original. Not 100% the same feel, but very close.

Re: Full Screen (F11) update?

Getting some more options might be really helpful for some games. There's some that use touch-screen, some using the "break-out box" via the User-port. Full-screen would be nice for all. This was the link: https://github.com/mattgodbolt/jsbeeb/issues/49.
