> Give your PSP away and get a nice programmer from > Newfound electronics? :o) Being immensely wealthy (but you know, I'd trade it all for just a little more) that's probably what I should do. However, tight-wad that I am, more info to get the best out of what I've already paid for Win3.11 on 486, no problems with PSP and MPLAB 3.99.06 for nearly 7 years Win98 on Pentium 266, PSP very flakey, with either MPLAB 3.99.06 or 5.30.00 My Mot emulator also works well on the 486 but has similar comms trouble on the Pentium. Things I've already tried are checking for conflicts, re-installing COM2, shutting off FIFO, and a few others I can't recall. Last night PSP didn't work at all, at least this morning after persisting for 30 minutes I did finally manage to program an F84A. But there's no guarantee you can program a second, it's like you start from square one each time you try to talk to the PSP. I really want to sort this out, it's more convenient to use the Pentium -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
