Re: ABUG SOUTH 22 to 24 November 2019 - Save the Date - NOT A BOOKING THREAD

\o/ Yay! Thanks for organising this venue again. It was a great weekend last time and so conveniently close for me at least. Look forward to the booking thread. :D

Re: Sega Light Phaser on a BBC Micro

Great progress Tricky! =D>

Like Mark, I have a stack of gardening jobs to do over the coming weeks before starting my new job in September. However I would love to borrow a rifle at ABUG please if anyone would be kind enough to lend one for a while.

Re: Having difficulty with TurboSPI

Just FYI that although POP and SCR do blatantly abuse the 12K of HAZEL (FS) RAM they do try and step around the areas that are known to be used in a standard Master DFS/MMFS setup that leaves PAGE at &E00.

I think SCR even works on ADFS thanks to Tom Seddon!

Re: Having difficulty with TurboSPI

Hey 0xC0DE, I'm surprised Twisted Brain loads (!) but in general having PAGE at &1900 on a Master is going to cause problems with more advanced software like Stunt Car Racer (and Prince of Persia) that requires PAGE at &E00 and all 4x available slots of SWRAM (plus ANDY and a chunk of HAZEL for good...

Re: Testing all RAM in a Master 128

Can you post a screenshot? My bad but TB kinda assumes a fresh boot in either MODE 7 or one of the 20K screen modes. Too much testing on an emulator rather than real hw! If you have the VLSI variant 6845 CRTC chip then it is known not to behave ‘correctly’ compared to the other manufacturers, eg Hit...

Re: Is an MMC DFS with PAGE at &E00 feasible?

Completely spit-balling here, but could you do a TAPE MMC instead of a disc one to keep the RAM overhead low? So the sd card just has tape images on it that you can select with some sort of *TIN command then everything else is just data streamed through the existing tape code, just with bytes coming...
