Has anyone tried to use the 65802 in an Atari 400?  I  have  been
thinking  of  giving  it a shot, because of the added instruction
capability.  I understand that it is compatible with the existing
6502.   Has  anyone  verified  this?  On the smaller side, I have
also heard that the 65C02 will work in the 400/800, but  not  the
newer 800XL and XE models.  Verification?

Also, I have need of a  serial  interface  board  for  my  Atari.
Since  my  Atari  is  mainly used for fun, I was thinking of con-
structing one of my own from scratch, that will sit on the serial
line  and provide support for at least two RS232 ports.  Has any-
one got a good design for one?  I am trying to work out a way  so
that  the  RS232 controller will be smart enough not to interfere
with the disk I/O requests.  I would prefer to  allow  RS232  I/O
and disk I/O over the same channel without specially toggling the
RS232 line off the serial bus.  Still, if anyone has any  brilli-
ant  ideas  of  how to build any sort of serial interface for the
Atari that interfaces through the serial bus, drop me some mail.
