The pgm file extension is also related to AKAI MPC family of devices. The MPC-1000, the MPC-2000, the MPC-2000XL and the MPC-3000 all use different program formats although they all have the same PGM file extension.
Actually the MPC-2000 and MPC-2000XL use the same PGM file format, but the latter (like the MPC-1000) wants samples in WAV format, while the former wants them in SND format (like the MPC-3000).
Use compatible tools to work with *.pgm files.
Probably can be exported to other formats.

A signature program is a small, highly condensed piece of code, commonly written in C or C++. It is usually three lines or fewer and compiles to produce an interesting pattern or function that may not be obvious from the source.
This source code is associated with Visual C++, Microsoft's development environment for writing and compiling programs on Windows. The pgm file holds the program's source code rather than its compiled output.
On Windows, use Microsoft Visual C++ to open and inspect the pgm file's source code.
There is no direct conversion for this source code. If you need a runnable program, use Visual C++ to compile the code; compilation creates program output rather than converting the source into another editable format.
