Re: Acorn System 5 Software

Just building my System 5 at the moment so will be pleased to try out the disks. :)

I'll most likely be running Drive0/2 from a GOTEK and Drive 1/3 will be a physical 3.5" floppy

Hi Phil, I'm intrigued at giving this a try on my RISCPC and I'm handy with Pi and/or Arduino but haven't yet jumped into CPLD/FPGA world yet save programming other peoples bit files for other Xilinx projects on the Forum such as ElPizza boards and YARRB -- on the todo list along with SMD soldering ...

Re: Today I received.....

A fantastic soft stretch cover for my ATOM/System 2/3/5 keyboard. Would highly recommend. I simply sent the WxHxD and paid via PP. Cover was posted with tracking from Spain and arrived within a week. I can't vouch for any anti-static properties, I must admit I didn't ask him -- maybe if you're inter...

Re: AcornDOS System version.

Does anyone have an image of the 4K Acorn DOS System ROM they can post here for me to do a quick check on my System3 with?

I can download the git sources and try and rebuild if not.

wanted: Vero KM6 or VeroTec KM6-II front panels

I am looking for a set of front panels for a 3U card rack:

10x 3U x 5E (5H) 25mm, Front Panels
1x 3U x 14E (14H) 70.7mm, Front Panel

Handles for front panels

Board fixings (x2 per board) for fixing each panel to a 100x160mm PCB.


Many thanks

He does an Electron/Master version or a BBC Micro version for the maxtrix PCB which is probably the main reason for them being separate boards. I found out the hard way that the keyswitc...

Hi Kees,

I can run a JOYMMC game I can get movement and fire by shorting out PIN31 to any of the PB0..PB4 pins

In which case, wiring everything up and running up an AGD game is all good :D
