Hello

I have been playing with the 64K PET memory expansion board on my 4032 in
combination with the Supersoft Graphics board. It works well having
identified 2 fault 4116 IC’s and replaced them.

I have found a text file with the source code for the add-on loader
(zimmers.net), made the necessary changes for it to work with the ‘acme’
assembler, fixed a few bugs and changed it to function as a load only
programme. I can now load larger image files into memory for graphics
displays (after first using a hex editor to point the file to the expanded
memory)

Does anyone actually have a copy of the other programmes that came with the
64K board, such as Add-on Mon, expanded basic with the associated basic rom
files etc. ?

Thanks in advance

Andy
