Tape?

Master Compact

Lack of 8271 emulation possibly causing issues for a user:

Olivetti Prodest PC 128S - see https://github.com/tom-seddon/b2/issues/187 - same as Master Compact?

Any news when serial support will be added? Beeb-Em has it but only on the Windows build. Would like to see if on the B2. There's a few things I'd like to experiment with.

tom-seddon commented 1 year ago

6502 second processor support will be in the next release.

tom-seddon commented 1 year ago

@nelgin What sort of things are you thinking of? I've been thinking about bumping serial support further up the priority list, as I've got a project in mind myself and it's a bit easier to debug stuff with an emulator.

I'm currently thinking a byte stream over a socket would be enough for my purposes. I'd be planning on doing file/clipboard support as well, as (famous last words...) it doesn't feel like it would be too much extra work.

nelgin commented 1 year ago

@tom-seddon I was thinking of using tcpser along with an emulated serial port, rather than using the computer's hardware serial port since many don't have them these days anyway, which would enable connections to the outside world.

Joystick support will be in the next release

Hope tape support will also come soon :)

For ROM mappers, have a look at what's been implemented in MAME:

Electron?

Can't decide about this. It's not got the BBC branding and the terracotta function keys - so maybe it's out of scope?

But, equally, it's got the 6502, and the MOS interface, and it's at least trying to be a BBC. So maybe I should.

Parallel printer will be in the next release.

Data is stored in a buffer, and you can copy it to clipboard as text (assuming text output only, no ESC commands) or save it to a file for use with a converter of some kind.

I know it's already on the list but I just wanted to cast an extra vote for tape. Back in the day they used to broadcast software over radio or sometimes even TV and it would be great to see if recordings still work.

tom-seddon commented 7 months ago

I hope to have Master Compact/Olivetti PC 128S largely sorted out in time for the next release. This won't include mouse emulation (yet! Sorry... mouse is still on the list), but it'll have EEPROM support for *CONFIGURE, and the digital joystick interface.

tom-seddon commented 7 months ago

Next on the list after that: probably tape (by popular vote! Also some overlap with serial port support, which I'd still like to do) - but possibly hard disk, as that would be useful (though not super high priority) for testing some BeebLink stuff.

Whichever happens first, the other will follow.

Econet?

Really hoping for hard disk support; I just imaged my old ST506 (yes, the real 5MB one) that I've kept carefully for the past 40ish years using the pdp8 MFM board, and am super excited that I can see traces of my old BBS that I used to run on there - some obviously BASIC code, some Viewdata pages, some text files. It's standard ADFS format with 256 byte sectors...

This may, or may not, be useful.

B2 is just software to emulate the BBC so not sure how you'd read the disk otherwise. You could see if you can find an MFM board for a PC and then use dd (linux) or some raw copy utility (windows) to save a file that could be opened in an adfs reader.

If you can pull an image I can try reading it for you, I have a registered copy of some ADFS software.

hfiennes commented 3 weeks ago

Yes, as I said I imaged the drive already (using the same tool as in that video) and have a disk image file - only one head on one track bad out of the entire disk, luckily. The extracted ADFS image works with BeebEm under windows, but there's currently no way to attach a hard disk image to b2 and I'd like to be able to use this without two layers of emulation :)
