     GzPk (v2) seems to work okay on our ROM-01 GS under ProDOS 2.0.3.
However, it may bomb if you start it (by double-clicking on the file name).

     What's supposed to happen is that the program scans the root directories
of all on-line volumes and lists .gz files it finds. Whether or not if finds
any, once it's finished scanning you should be able to browse to the volume
and the folder which has the .gz file you want to convert.

     Sometimes all of this works. Sometimes not-- i.e. the scan never happens
and all you get is a few garbage characters on the screen and no browser.

     The only way I've gotten the program to work reliably is to have the .gz
file I want to convert in the same folder as the GzPk program. (Trying GzPk
v1 is another option. It avoids fancy stuff and just asks you to enter the
pathname of the .gz file.)


     So, try moving the .gz file you want to convert into the same folder as
GzPk (v2). When you start GzPk it should list the file. When you highlight
the file name and press RETURN, GzPk should work for a few seconds and then
stop. When you exit, you should find that a .zip file has been created in the
folder.

     Whether GzPk always succeeds in producing a good .zip file is another
question. For sure, there have been a few cases when GzPk plus PMPUnZip
failed to produce the expected .dsk (or .shk, or whatever file). Yet, on the
PC, WinZip had no trouble extracting the .dsk from the same .gz file and the
.dsk booted fine on AppleWin.
