More on ProDOS and Nonstandard Apples

In the March issue we published Bob Stout's note on how to make ProDOS boot in a Franklin computer.  The current issue, (No. 9) of Hardcore Computist points out that the address given in that note didn't work for the ProDOS version dated 1-JAN-84.  Apparently Bob was referring to an earlier version.  The correct address for the NOPs is $265B.

In a similar vein, inside this issue Jan Eugenides points out that ProDOS will also fail in an Apple with a modified Monitor ROM.  He then gives a slightly different patch to defeat the check code.
