To patch ProDOS to run on a Franklin ACE 1000, 1100, 1200, etc. and probably MANY other clones and workalikes, use a sector editor to search for and replace the following byte sequences in the file "PRODOS": Search for: Replace with: -------------- -------------- 69 0B D0 03 69 0B EA EA AE B3 FB E0 38 A2 EA EA E0 38 This works for all versions of ProDOS up to v1.9. It may also work with v2.x if your Franklin or other clone works properly with a 65c02 or 65c802 CPU. 22 April 1994 John D.
