I know that the Amiga and Atari ST's had their
versions, but
there was a fairly major format change at some point that could cause
a problem for older versions of the software on non-PC clones. If I
recall correctly, PKZIP/UNZIP was actually an outgrowth of PKware's
earlier PKARC/PKXARC programs and it changed names when Sea
Associates complained about the closeness of the name to their
products (ARC & UNARC), whcih they were compatible with. This was in
late '87 or early '88 and BBS's started boycotting the use of
ARC/UNARC and switched to ZIP as the defacto compression standard.
They didn't just change the name, they changed the format as well.
I'd been a big ARC user, having switched from SQ/USQ/LU/LDIR etc.
PKARC and PKXARC were so much faster, I switched immediately.
You know the rest of the story.
I kept DOS (for sure, and maybe CP/M) executables of them
so if anyone needs them, let me know. However, they don't
appear to run properly under CMD.EXE (maybe CONFIG.NT needs
a tweak).
