A telescope mount controller I have to repair drives the motor H-Bridge using a programmed DSPIC33FJ12MC201 IC.
So far so good - but one of them has gone bad

If I can pry the firmware image out of the supplier - what can I use to programme these babies - neither my Galep-4, nor my Dataman 48XP recognise that the DSPIC33 exists

There's a fix pin socket (0.1" pitch I think) right next to the IC which is clearly intended for programming it with pin 1 to Vpp, 2 to Vcc, 3 to Gnd, 4 to PGD, and 5 to PGC I htinkn these are referred to as PIC ICSP MINI 5 PIN sockets.
Thanks
David
