Poly800 conversion
2004-07-21 by expoligy
Hello,
My name is Gerrit from the Netherlands and last weekend I aquired a
Poly800 Mk1. I want to convert it to Mk2 and saw some schedules about
this on the internet but then I have to piggyback the eproms. I don't
want to switch from EX/Poly 800 mode. I want to fit it all in one
eprom, sysex and keyboard routines.
This EPROM will be bigger that the old one but my guess is that it's
not too difficult to add an extra address line to the processor in
order to have full functionality.
The hardest thing is... to find a Mk2 ROM-Image. Does someone have
this so I can burn it? It would be GREATLY appreciated.
Thanks,
Gerrit
