The A versions are listed in my PICSTART+ menu. It's version 3.10.00, which
I had to get from the 184.108.40.206 MPLAB, IIRC.
I upgraded the Picstart firmware in order to be able to handle the PIC16F676
chips, but I'm not convinced it is handling them properly - the calibration
information *seems* to be destroyed (I have not fully investigated this
issue yet) and you cannot program a chip without first erasing it
