Re: [xpantastic] Why no Xpander mod. matrix implementation?

>>Well, you could do alot if the software was rewritten. But to do that you would need development tools from that era,

>>like a 6809 Emulator/debug system and so forth.

I'm sure these are still available.

I know of people doing 6809 development, but it's higher-level languages.

>>board and display I/O etc.

Hitachi makes a 3 (or4??) MHZ pin compatible replacement for the 6809, that is used
in the computers by the above mentioned people. I think that is the E version of the 6809, which
isn't pin compatible with the 6809 in the Xpander (but is compatible on the instruction level).

A pic, or Arduino could do the job and without the zipper noise from heavy modulation, if it had enough I/O lines ;-)

Can you imagine o w many mod routings could be done by a modern processor?
100s, or 1000's per patch!!

>>Still not an easy job though :-)

I'm sure you can get beta code out to us by Monday though ;-)
