AHA! It's very unlikely that anyone has used that part due to form factor.
Most likely you'll have to create an ICSP style cable. A quick glance at the
programming specification doesn't indicate anything usual in terms of pins
used for programming. You may need to doublecheck to ensure that the
programming algorithm is exactly the same as the DIP/SSOP parts like the 18F452.

In any case your best bet is to create an ICSP cable. A 40 pin jumper cable
wired to a 8 or 10 pin header should be more than adequate. Just be sure to
keep the cable length short.

I'd pick the 40 pin ones because it's most likely that you'll be able to
program the part with a 18F452 selection. Just a guess mind you.

No problem. Good luck.
