So the differences between v3.9 and v4.1 is just the Y2K compliance.
That is actually why I am trying to find the latest version so locating
the patch or finding the v4.1 download would be perfect.


Then you need to be aware that there were two different tacks taken in
making it deal with Y2K.

Glen's own method was to use the fact that a 7-bit field could hold
values greater than 99, to extend the "year" field to 127 (2027).
This approach has the advantage that date sorts of files are in the
correct order by default.  The disadvantage is that many applications
that use the ProDOS date are unprepared for year values over 99.

The method for date representation extension proposed (and implemented
in many systems) by Apple was to move the "window" from 1900-1999 to
1940-2039.  This is compatible with most applications, though many will
still get the century wrong, displaying 19 instead of 20 for years in
the 00-39 range.  It also causes 21st century files to be date sorted
prior to twentieth century files, base on the year field alone.

I prefer to stick with the Apple definition, patched into ProSel 8 by
Bev Cadeaux (A2MG), but YMMV.

How any of this relates to the ProSel *version* number, I have no idea.
My current version is v4.1, and it is the one with Bev's patches.  (BTW,
only ProSel and one utility actually needed patching--but I forget which
one at the moment.)

Hello,
    I am trying to find a copy of Prosel 8 v4.1.  First off, I am
curious if it is freeware these days or if I would have to pay.
Second, if anyone knows where to buy / download it it would be
appreciated.  I checked a bunch of sites but kept getting 3.9 which
seemed to be free but would like to know.

Kellion...



When Glen Bredon passed away, his widow made Prosel/Prosel 16 freely
available to the Apple II community. There are a couple of versions of
the last release floating around that have been patched by different
people to make it Y2K compatible.
