AMD 9511, 9512, Intel 8231, 8232 wanted, will trade National MM57109 - test-drb@ccmp.vtda.org

27 Jan 1999

Peter Boyle, along with Wayne Wall, at that time, of the Denver Area 6502
users' group, wrote driver routines, perhaps the ones which were used here
to patch the 9511 into the Applesoft basic, for the group's Apple users. 
It would surprise me to learn that anyone still has this stuff, but if they
do, you won't find anything much better.  He also started on a set of
drivers to go with his XPL0 language for the 6502.  I'm not certain whether
that task was ever completed.

The drivers are quite straightforward, due to the device's architecture. 
However, as I recall, the patching it into the Applesoft basic was a pain.

  Speaking of which (:-)), does anyone else
remember a 9511 card for the 
 Apple ][. I found one in a pile of boards that were being thrown out, 
 along with the manual (including schematic), but without any software.   
 I used to have one of those years ago.  There was a patched version of
 Applesoft BASIC that would use it.  I'm not sure what other software was
 written for it.
