I find I have a need for an ARM code disassembler for RISCOS 3.1 machines. Can anyone recommend a good one?
I remember using !Dissi by BASS. Seemed to be quite advanced back then (on my 1 MiB single floppy A3000).

Have fun

Re: RISC OS relicensed: now under Apache 2.0!

Porting the OS to other platforms would widen the audience significantly. Don't forget to develop that super-fast emulator for ARM code before (try to start with an ARM26 code emulator and put it into ArcEm and RPCEmu), or else it won't be very useful and would leave the widened audience without mu...

Re: What's going on with the A4x0/1's serial port?

I think there was a SerialUtils module that got distributed with most boot systems that more standardised the functionality of the serial port - that could be why you're not seeing any problems. I've never had any problems with serial comms between A5000 or A480 and Master, PC or Spectrum. The seri...

Re: What's going on with the A4x0/1's serial port?

After an afternoon to mull things over, I'm inclined to believe that !Connector is replacing Acorn's serial port driver with its own (hence how it can do things that Acorn's original driver for the non-82710 machines couldn't do) but that the A420/1's hardware supported the use of those pins for si...

Risc PC mainboard power plug?

Hi,

is the 6 pin power plug for a Risc PC mainboard available somewhere, or only by cannibalising Risc PC PSUs? The RPC TRM only says "6 way power in", and I don't recognize the plug's shape as anything "standard".

Re: RISC OS 4.39 FileCore Limits

The limit is definitely 256 GiB, I think even since RISC OS 3.6 (although you'd be insane to use such a large disc with non-plus format, because object size gets just too big). I don't think 4 GiB was ever a limit anywhere, apart from the advised maximum in PRM Vol5a for "big disc" filecore. Sounds ...

For 32-bit machines they've implemented PPPD, which should allow full networking albeit limited to 19.2kbps on the A3010.
Is that an ESP32 limit? The A3010's serial port was happy to communicate at 57600 or even 115200 bps if you were lucky.
