Walter,

Are you doing anything special with teh Table Instructions in the 17C42.  We
are looking at putting some I/O devices and RAM in the external map and want
to use those instructions to access it.  Perhaps a PEEK and a POKE built in?

Thanks,

John.

PS.  You mentioned on the phone a while back about some amazing upgrades
that were in the works.  How is it going?

We have been working on supporting both RAM and ROM out there.
In the RAM case we are looking at the different means that users will
hang RAM off the processor. (Byte wides or 16bit wide) It gives
many different combionations.

I/O devices we will support in the same way we do on the Z8 with
port declarations and modifiers to identify which address space a port
is in.

reasonably well. It is curenntly 2nd in line for release. It is
strange we can develop in parallel but elease takes everyones
undivided attention. Sure a change from the days when we could
copy a few files from a development computer and ship them out
the same day.

Thanks for the comments you have been making on the PIClist.
