The HESMON cartridge can acces the disk drive. Attempts to access the tape drive produce an "IO ERROR #5". Upon examining the memory, I discovered the Basic warm start vector at $0302 had been set to $F72E. I changed it to it's normal $A483 and exited HESMON. C64 Basic!!! I can load and execute programs just like a standard C64. The only difference I have found so far is the tape drive. Any attemp to access the tape drive produces a "device not present" error. $F72E is where the tape routines normally are. It looks like they have been replaced by the Games System screen.
