Yes, that is true about the pinout. It's a nuisance if you have PCBs
and find that INT isn't where it used to be for example. Aside from
that, porting will be firly simple but involves some s/w adjustment

The 18F has a few more instructions, some new (eg TABLE, MULxx,
CPFSxx etc) and some modifications. FSRx instead of FSR, RLCF/
RLNCF for RLF for instance

I did port quite a few related projects over from the 88 to the 1320
and had no particular problems. The minimal time spent doing it was
well worth the effort. Particularly in one set of boards which needed
to process ASCII strings. The multiple FSRs and better RAM
organisation turned a horrible swapping and copying mess (F88) into
a quick and efficient handling routine (F1320)

Please do try the 18F, and even the 24F, 30F and 33F. You won't
be disappointed

For programming I recommend Olin's (see my signature). They are
inexpensive and run independently of MPLAB. Which is an absolute
boon now that MPLAB is unable to open a SIM and programmer
at the same time
