Sad news when you've got such fantastic projects.

Could you tell us more about yourself and your relation to the Acorn machines and in particular the 32 bit systems ?


I'm not really an Acorn guy. Except that we used acorn at school. But I find building and debugging retro machines in FPGAs very relaxing.

I was working on an Atari FPGA core when i realised Till Harbum was further ahead except in a few areas. So he took my MFP implementation and merged it with his and I started my own Archie project.

I became a bit of an ARM fanboy in recent years and wanted a platform to develop some interesting hardware. I've got a few Acorn machines now including a A540, A4000, A3000 & RPC (StrongARM). But I also do Amiga stuff too. I have a bunch of Amiga machines and custom boards made for them.

I've been travelling a bunch for work lately so i've not been able to keep my channel up to date or do much new work. But hopefully thats changing now.

Just a little note to say I got my MiST board working again so I may post some updates. Once again the major feature missing is an SD card driver which I am struggling to write and given my day job is software its not something i get too enthusiastic about.

A blog would be lovely, with plenty of pics and in layman's terms perhaps. Though things seem to have come a bit of a cropper here.....

How much is emulation and how much is ULA, or however they do things to make it 'real'?

Martin, what did you need to do to get a picture? I tried with the latest core, with the rom files of RiscOS 3.10 (merging the 4 rom files on Windows using command "copy /b rom1+rom2+rom3+rom4 rom" and then renaming the 'rom' file to 'riscos.rom' and copied to the SD card. I used a blank SD card where the latest core was renamed to 'core.rbf'. I do not get anything displayed or sound at startup. The MiST gives 4 orange LED flashes and repeats that a few times when I use the reset button.

UPDATE: I tried with the other core (archimedes_150407_r991.rbf) and that one worked. So there is probably a compatibility problem with the latest core.
