Re: BeebEm Mac - Info

Why does it have to be moved in that way? :?: I guess that's just another way of removing the security restriction? It's not really of any consequence as this will all be resolved soon enough anyway. I don't think it has to do with security as you still need to give it permission to run. You can ex...

Re: BeebEm Mac - Info

Just tested on Mojave on a real Mac that has never had BeebEm on it before. It runs OK. Need to first copy the BeebEm4 app bundle to the desktop and then move it back into it's folder (just as with High Sierra), and need to right-click and select Open to get the dialog requesting permission to run (...

Re: BeebEm Mac - Info

I haven't noticed any differences between High Sierra and Mojave (latest developer version running on a real Mac Mini) as far as app signing requirements go. High Sierra enforced certificates more strictly than in the past so incorrectly signed (or incorrectly bundled) code could prevent an app runn...

Re: BeebEm Mac - Info

I use a MacBook Pro as laptop and use BeebEm and B2 on it. Also use B-Em for Windows on it using WINE and under emulation but prefer the (Mac) BeebEm for its integration... Also tested the rough B-Em port. I suspect that it might be easier to improve and extend that than to rewrite the Mac-specific ...

Have you tried swapping the keyboards (with the ribbon cable) to rule out a faulty ribbon cable (or poor connection) as that can result in some weird I/O related behaviour.

Re: Acorn's Second Processors and the Tube - what, and why

the tube ula and the emulated second processor is all written in assembly lang? Maybe I read this question differently to everyone else since nobody commented on it, but the emulated second processor (e.g. Z80, 80x86,..) does not "all" need to be written in assembly, so existing emulators for vario...

Very nice. Will this require the VideoNuLA or will it run without with “interesting” colours? I’m also a little curious about how you are doing this.

Re: Tubelink EXROM and UTILRAM

That's because *CO. matches *CODE in the MOS as the MOS is checked before any sideways ROMs are checked. If you really really want to embed abbreviations in code you should only abbreviate it to such an extent where it still makes sense in English, ie *Config. *Desk. *Del. not *co. *des. *de. Stric...

Re: MMFS Development and Support

Could an "own file system variant" be implemented as a build-variant of MMFS like your E, M, T, U variants? In theory, it would be really useful for file management and archiving work even if some games break when booting from it. The "DFS emulating" version could still be used for playing those ga...

I am starting to wonder if MMFS should have it's own file system number and handle range: http://mdfs.net/Docs/Comp/BBC/Filing/FSNums http://mdfs.net/Docs/Comp/BBC/Filing/Handles This would allow it to co-exist with DFS, and in the Master (or a B with MER) files could be copied between the two.

Re: MMFS Development and Support

Not sure if this is by design or accident, but the Master Emulator ROM and MMFS do not work as expected when MMFS is the active file system. The emulated MOS commands that use the DFS, such as SRLOAD, give ""Bad filing system name" with MMFS.' On the same beeb, TurboMMC and a "real" DFS work OK with...

Only negative with it is that it (surprisingly) doesn't accept *ST. or *CO. shortcuts for STATUS and CONFIGURE A little further testing reveals that UTILRAM supports *ST. as a shortcut but not *CO.

Re: Tubelink EXROM and UTILRAM

With MMFS and the Master Emulator ROM, using commands that access the DFS (e.g. SRLOAD) gives an error message about invalid/unknown file system. So MMFS is trampling on DFS's workspace? Have you confirmed that by disabling/removing MMFS? . Did a little extra testing now and it appears to be specif...

Anyone got EXROM or UTILRAM from Tubelink? Both were supplied on disk in 1987... Thought I recognised "Tubelink", so had a quick check and I've got UTILRAM... whether the disk is readable is another matter :P I'll attempt to transfer it at the nearest available opportunity, or sooner if possible :)...
