Even though there are over 2000 subscribers on the list, sometimes it may take a bit for someone to formulate a response. Did you check the microchip docs as to what version on MPLAB and what firmware revision of the PS+ you need? Do you have those? Have you simply tried programming the 18F8620? If so what happened? Generally a specific question or issue will get more attention than a general one. In some ways you question below kind of sounds like "How's the weather where you are today?" Just some thoughts.

Thanks Byron, I will try to rewrite my question. Tha 18F8620 is a TQFP with 80 pins (there is only this type). Picstart has a ZIF with 40 pins. is there any socket to convert it? if not, what are the RB6 and RB7 pins in picstart that I have to use to program this PIC using ICSP?

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. > > if not, what are the RB6 and RB7 pins in picstart that I have to use to > program this PIC using ICSP? 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. > > Thanks No problem. Good luck.
