Re: Are there versions of BBC Basic with extensions (like procedures)

Now I'm looking for an extended version of BBC Basic (preferably for the PC, so I can make use of more memory). BBC BASIC for Windows: http://www.bbcbasic.co.uk/bbcwin/bbcwin.html Another option is to get a Raspberry PI and run RISC OS: https://www.riscosopen.org/content/sales/risc-os-pico However,...

Just to be clear, the incompatibility isn't with the VideoNuLA board but with the demo :)

Re: Acorn 3000 4mb Ram Expansion

Wouldn't indicate there would be something to change?? Or are they 'passive' model identification? I made some notes on this when I was upgrading my 1MB board to 4MB. The bank signal is tied high on the board for 1MB (2MB in total) but connected to A9 (again on the board) for 4MB. I guess the OS th...

From memory, I don't believe so.

However, there are sometimes links on the board to differentiate between 1M and 4M versions.

Re: NuLA demos

Thanks for putting so much effort into looking at this.

Might the SPI OSFIND be overwriting the filename block? What happens if the filename is completely reset to "A.01" rather than just resetting the "01" bit?

Re: Book: Assembly Language Programming for the BBC Micro

Excellent job - I've had this book since I was a kid and it's a great introduction to 6502 coding on the Beeb.

It seems to have been very popular too as I've picked up numerous copies with other Beeb stuff over the years.
