Re: OSWORD &7F on DFS vs MMFS

Just to add: my problems with MMFS are solved. My code is now running on DFS as well as on MMFS. Turns out that I made a small mistake in my interrupt driven screen drawing code that wasn't giving any problems on DFS but messed things up on MMFS. Solved!

Re: *SOLVED* Testers wanted! Anyone with Acorn Electron + DFS and/or MMFS hardware

Good news: I have been staring at this problem for days but this evening I found that my interrupt driven screen drawing routine was faulty. It didn't give a problem on DFS but it created a mess when run on MMFS. Consider it SOLVED but I'm pretty sure I am going to need testers again in the future :...

Re: Testers wanted! Anyone with Acorn Electron + DFS and/or MMFS hardware

More details and a first test disk. Assumption: DFS test is working in 3 Acorn Electron emulators. It should work on real DFS hardware AND it should work on MMFS hardware. Reality: I have no real DFS hardware to test on. And my tests fail on 3 different MMFS systems (all EPP based though). Test: loa...

*SOLVED* Testers wanted! Anyone with Acorn Electron + DFS and/or MMFS hardware

I need some help from anyone willing to run a few test programs on an Acorn Electron with any DFS and/or MMFS hardware. I've got some simple sector loading tests working on DFS in all Electron emulators. And I've been testing on a few MMFS hardware solutions that keep failing these simple tests. I h...

Re: Equb equw equd etc

BeebAsm definitely supports a list of comma-separated values after equb/equw/equd/equs. The values can be decimal, hexadecimal, binary, characters and strings. Edit: and variables, labels, macros, etc.

Re: OSWORD &7F on DFS vs MMFS

I have tested on 2 products by Ramtop. The ElkSD64 connected to the Elk expansion port. And the ElkSD-Plus1 which plugs into a cartridge slot of the Plus 1.

What is the expected speed of MMFS on such a setup?

Re: Elaborate Repton 1 Electron Cheat !

I wrote about it on Twitter not long ago:

The loader (REPTON0) of the Electron version is deliberately littered with undocumented NOPs it seems. It doesn't fool my debugger 😉 Execution starts at &2BDF after an initial sneaky BRKV redirection.

OSWORD &7F on DFS vs MMFS

I'm trying some test code doing raw sector reads (OSWORD &7F) on my Acorn Electron on DFS (in an emulator, btw) and on MMFS 1.4x (on a real Electron). My first question: I know MMFS is based on DFS but the underlying medium (SD-card) is much faster. Is MMFS artificially kept at the same speed as DFS...

It seems you also removed the 'protection' code in the loader that uses undocumented opcodes, correct? Keep up the good work...

Is it at all possible to create one that keeps PAGE at &E00 and does not use any kind of RAM of the Master itself, i.e. to have SWRAM on the Master version as well? Some ...
