Congratulations! Will a version of VICE that includes this be released soon? If not, I will build it from source and try it. > Is that the same John Toebes who later got involved with Amiga software > and Lattice/SAS C? Yes. He was joined on the Amiga side by the editor of "SuperPET Gazette", Dick Barnes, who started a journal called "The Amigan Apprentice & Journeyman". > Removing the dongle check would have been interesting.

As you have probably discovered, the Waterloo software executes from the bank switched RAM at $9000. The 3-board SuperPETs use 4116s for this memory and often have a bad one. This is usually the problem when a SuperPET won't run the Waterloo software. The ROMs do not test this memory. The checks for the dongle will probably be in different locations within the banks at $9000 for each Waterloo program. Since the microEditor has already been cracked, it might be a good idea to look at a different one like microBASIC. There are two major versions of the Waterloo software (1.0 and 1.1). The later version has bug fixes and adds the COBOL language. COBOL is not on the power-up menu but runs when you type "cobol" at the menu. The menu will actually load any filename. I have commented disassemblies of some of the Waterloo programs from John's disks. I will send those disk images soon. Also, last month I desoldered a 6702 from one of my SuperPETs and sent it to Greg James of the visual6502.org project for chip shots. It may take some time before we get them but hopefully the photos will help unlock the secrets to emulating it.
