Again, the 'Atari strike force' did a major hit:
Therefore, we greatly thank Harry B. Stewart for given the program and the source code into PD, we thank Kevin Savetz for doing that job, contacting Harry and interviewing him, we thank Atari_Ace for typing in the source code, verify it and making a rom and a cart image of it and last, but not least, Allan Bushman for preserving the APX version of Extended WSFN including the manual.
Wow, what a time. It proves again, how much can be done, if we all work together! :-)))
So, as of 2017, just the APX cas version is missing to make it complete. Any hints about it are very welcome at any time.
A giant leap further for the 100 % digitizing project. :-)))
