VisiCalc (VisiCorp) =================== This is a once-famous spreadsheet for the Commodore PET 2001 and 8032 (should work on any PET with at least 32Kb RAM). This program included a chip which plugs into a socket on the PET motherboard. The program will not run unless the chip is present. The chip is probably an early form of "dongle"-type copy- protection. I do not have this chip or a PET disk drive, so I am unable to test the program. If you discover how to patch the programs to run without the security chip present, please let me know. The label reads: --- VisiCalc® PET 2001, CBM 2001 Program Diskette and CBM 8032 32K [VisiCorp logo] for 2040 and 4040 One of the VisiTM programs Diskette Drives from VisiCorp by Software Arts, Inc.
