Following on from the B128 and BX256 machines announced at the Chicago Electronics Show in June 1982, the elusive CBM 700 was
the much delayed replacement for the CBM 8032 that promised to bring Commodore Business Machines in line with more modern micro
computers, and maintained the same Porsche design and the promised B and BX series. The CBM 700 was equipped with the MOS 6509
micro processor, the same SID chip as used in the C-64, and 256K, expandable to 896K. On top of that there was to be a plug-in
Z-80 micro processor board that would add CP/M and access to a vast range of professional software, as well as an 8088 16-bit
micro-processor board for CP/M-86 capability.
There was a built-in RS-232C interface for hooking up modems and printers, Commodore's traditional IEEE-488 interface to support
the full range of Commodore peripherals, a real-time clock, an enhanced Microsoft BASIC upward compatible with BASIC 4.0, audio
system output, monitor output, and a cartridge slot for plug-in games and other software. High-level languages such as U.C.S.D.
Pascal would also be supported, and the CP/M made possible languages such as FORTRAN, COBOL and APL. It came with an 80 column 25
line built-in "tilt-and-swivel" green phosphor monitor, dual 5¼" disk drives and detachable keyboard. Its 94 keys
included 10 programmable function keys, a separate numeric keypad with CE, 00, ENTER and math operators, a key for each cursor
arrow to support the full-screen editor, a large and easy to find RETURN, Pi, ESC, CTRL, INS/DEL, RUN/STOP, NORM/GRPH, CLR/HOME,
OFF/RVS, and the full CBM business character set with PET graphics symbols.
A release date of October 1983 was announced but the machine was not released as far as we know.
