It appears to be the Olimex programmer, which should work, but I don't have
one to test with.
You may need to modify the programmer support section in the pic definitions
in file 'picdev.c' for it to work. It depends on how the programmer
identifies itself. If it reports that it's a PicStart Plus, then it should
work with picp. If not, I've begun adding support for Olimex in picdev.c, but
someone else will have to test it.
BTW, in the next version of picp, device info will come from a configuration
file rather than being compiled into the code.
The config file can have either a short version to keep its size small:
(example entry)
[16F84]
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
PICSTART WARP JUPIC
[16F84:def]
04 00 3f ff 3f ff 00 7f
00 7f 3f ff 3f ff 00 ff
00 ff 00 00 00 00 00 00
00 01 20 00 04 20 07 01

[16F84:defx]

3f ff 00 00 00 00 00 00
00 00 00 00 00 00 00 00
or a long version more meaningful to humans:

Picp will read either format.
