FLEX on Acorn 6809 System Computer ?

[AcornChris]

I've recently built a replica of the Acorn 6809 CPU Board that fits in with their 6502 based Eurocard Systems:

However I would love to get FLEX running on it !

Acorn had a customised version of FLEX which could 'talk' to their hardware (keyboard, VDU , floppy etc.) but I haven't been able to track down a copy of it so this is a bit of a long shot but can anybody on here help ?

Hi. There should be enough to find on internet. Is already from 1990 or earlier. Looking for FLEX 6809 returned a link to : "https://archiveos.org/flex/". Most likely sources. Recently asos found a PC driven Aztec C Compiler for Commodore 64. Is an Aztec C compiler with CC65.exe AS65.exe and LL65.exe, all Dos/Windows executables so you can Cross Compile on a PC and move your Binaries to your Acorn 6809 Bus computer. I also used Aztec C on Apple IIe around 1985.

I may have a copy...
I used to have the loan of one of these systems, and think I may still have some disks, but goodness knows if they are still any good.

I built a computer around the Acorn 6809 Eurocard, and ran FLEX09 very successfully for years. However, I used the original TSC version. I did this by simply relocating the Acorn monitor ROM, to overcome the addressing conflict. Simple.
