Atari PIC programmer
This is a tool to program a PIC microcontroller from an Atari 8bit computer using the JOY2PIC interface.
The tool consists of two main programs, both run on the Atari:
READHEX: This program reads an existing
.hexfile with a PIC firmware and builds another atari executable capable of programming the microcontroller.
PICREAD: This tools reads and displays the contents of a PIC memory.
SETVPP: A tool to activate the VPP (programming voltage) signal in the JOY2PIC interface, this allows measuring the output voltage to assure that the programming will work.
The JOY2PIC interface
To use this tool you need the JOY2PIC interface, developed in the AtariAge forum, you can see here the basic schematic:
For further instructions, see the atariage forum posts: http://atariage.com/forums/topic/247065-create-icsp-programmer-for-embedded-micro-controller-chips/?p=3572599
The provided Makefile works in any Unix like environment and assumes that the
tools are available in the path, so simply typing
make will generate the
picprog.atr disk image.

Also, in the
bin/dos directory are two programs extracted from BW-DOS 1.3
disk, those are under the following license:
BW-DOS may be freely used and distributed under following conditions:
- Only the whole and unchanged master disk may be distributed,
- It may not be sold, excepting little costs in PD services,
- When used as a part of another software package, the whole package may be marked with a "(C)", sold etc.; in this case it's possible to exclude files from BW-DOS, but all distributed files still must be unchanged, and an information where the whole BW-DOS is available must be included.
I assumed that the last clause means that I'm able to distribute the two unchanged files.
