The 600/700 a.k.a. B series a.k.a. CBM II machines seem to be really business-oriented. There is an interface for a cassette unit, but no firmware to drive it. An external cartridge is required for accessing cassettes. Thanks to André Fachat and Ullrich von Bassewitz for documenting all this on FUNET. It was a small disappointment for me to find this out. But I think I will use the cassette port anyway for my data link. After all, it is the same connector as in other 8-bit Commodores (except the 264 series), and the RS-232 port might be used for something else. One thing is unclear to me: What are the main differences between the 600 and the 700 series? I guess that the main difference between x10 and x20, x=6 or 7, is the amount of memory: 128 or 256 kilobytes. My 720 does not contain any add-on boards: just two adapter boards for localized KERNAL and character generator EPROMs. One more question: Does anyone happen to have three spare rubber pads lying around? The keyboard is missing one, and the computer is missing two of them. The pads are circular, with a diameter of about 2 centimeters or 3/4 inches.
