Re: Please run a little test on your Electron

Any other testers with an Electron and a minute to spare?
Especially looking for test results on an issue 2 Electron, or any Electron with some hardware add-ons.

Re: The V flag

While getting all 6502 instructions (including undocumented) 100% correct in my Acorn Electron emulator, this page was invaluable to me for understanding all the ways that the V-flag is affected, especially in Decimal Mode.

Tested it on my Issue 6 with MRB

Issue 4 + GoSDC works just fine.
Thanks for taking the time to test it on your 2 Electrons, very much appreciated!

Please run a little test on your Electron

My latest demo effects on the Acorn Electron rely on 100% accurate timing (cycle counting). I've only got issue 6 Electrons (and German issue 1) to test on. I'm a bit worried that my timing may be off on earlier models of the Electron. Or with various peripherals attached. So, anybody owning an Elec...

Re: German Electron?

My original Acorn Electron (that I still heavily use) was purchased in The Netherlands (where I'm from) and this is a German Electron with the heavy shielding inside. I'm guessing all the Electrons sold here were required to have it? Just curious: I bought 3 other Electrons on eBay and it's never re...

Re: BBC Micro and Acorn Electron demo effects

You are on the right track. However, quick colour palette changes are not necessary. Once every frame (or rather, field) is enough.

Re: LAND - A Multi-User Dungeon (well almost)

You may want to look into the directives incbin and include in BeebAsm to create your final binary from separate data files (incbin) and separate assembler files (include). Makes it easier to manage smaller data or text files that get literally assembled into one final binary.

Re: LAND - A Multi-User Dungeon (well almost)

It's best if you use a PRNG (pseudo random number generator), for instance from one of my demo effects: .rand16 { asl zrnd rol zrnd+1 bcc r1 lda zrnd eor #$E7 sta zrnd tax lda zrnd+1 eor #$8D sta zrnd+1 rts .r1 ldx zrnd lda zrnd+1 rts } .rand8 { jsr rand16 ; 1 bit of entropy per call jsr rand16 jsr ...

Re: LAND - A Multi-User Dungeon (well almost)

The .asm file is a text file as input to beebasm. Create it with your favorite text editor. It doesn't have to have .asm extension though. I usually name my source files .6502
As long as it is a plain text file.

Very handy is VSCode with 6502 syntax coloring. Same goes for Notepad++

Re: LAND - A Multi-User Dungeon (well almost)

That's because it's a command line tool. It will not open a GUI (window).
See also: https://github.com/stardot/beebasm/blob ... /README.md

Try opening a command prompt (cmd) and then type beebasm.exe --help

Re: Achieved STABLE RASTER on Acorn Electron

Yes, if you (crudely) time the difference between Display End interrupt (sometimes mistakenly called VSync even by me :mrgreen:) and RTC interrupt, you can determine if the next field will be even or odd. Actually, I don't care WHICH field I'm in as long as my code always starts in the SAME field. E...
