Doug,

I think your peek and poke macros will cause problems on PCs due to the
segmented nature of the beast.

With the compiler I use (Aztec) and a large data model, in order to peek
at
(say) 0xf0000 absolute, the address becomes 0xf0000000 with a double
word.

I don't think any C compiler (at least known I know off) does the
conversion from absolute addressing to segment/offset on the fly.  I
know Aztec provides several subroutines to do this.
