Oh boy, is this really so long ago that people tend to mix up everything? (Sorry, no flame intended.) These were two different things: A) The SuperPET, or MMF 9000, had a 6809 coprocessor board, where this board carried its own 64 KB RAM. (See other postings about the Waterloo software.) B) The 8096 had only the 6502, and the new 64 KB were accessed via bankswitching. And there was software: It came shipped with a BASIC interpreter from Germany named LOS-96. And, not to forget: There was a wonderfull version of SuperOffice (Superbase + Supertext) by Precision Software, yes, the direct predecessor of Superbase for Amiga and now PCs. The last model of this computer series was the CBM 8296 with 128 KB RAM, where you could copy the ROMs into one of 32 KB banks and modify them just like in the C64. And then there was the same machine with a 8250 floppy built-in, called CBM 8296-D. Ah, and not to forget: The 8296 was developed here in Germany, in our Braunschweig engineering department. -- Best regards, Dr. Peter Kittel // E-Mail to \\ Only my personal opinions...
