  * cbm720se [Commodore B256-80HP/720 (Swedish / Finnish)]

For each system, MESS supports emulation with two cart slots, "cartridge1" (cart1) and "cartridge2" (cart2), for cart dumps in .crt, .10, .20, .40 and .60 format.

Also notice that a "quickload" (quik) feature is available for .p00 and .prg files.

== Keyboard ==

These systems require full keyboard emulation to work correctly. At startup, full keyboard emulation mode is enabled by default. Whilst in full keyboard emulation mode, some key associated functionality may be disabled (like the <key>Esc</key> key for EXIT). The keyboard emulation mode is toggled using the <key>Scrl Lock</key> key (by default).

Original Keyboard: Full stroke 94 key with numeric keypad and function keys

===== Known Issues =====

The emulation of these systems is Preliminary.


===== History and Trivia =====

The Commodore 700 series featured the same hardware basis as the 600 series but had a built-in tilt-and-swivel monochrome 12" monitor, a detachable keyboard and housing for two 5.25" floppy drives.

It was said that the 5/6/700 cases were designed by Porsche, not the more familiar Porsche auto factory, but the separate Porsche Design firm.

Three versions were available:
  * 710 (CBM 128/80 in USA): 128 KB RAM
  * 720 (CBM 256/80): 256 KB RAM
  * 730 (CBMX 256/80): 256 KB RAM and coprocessor

Both versions could be purchased with a built-in dual floppy disk drive which was compatible with the external 8250 dual drive unit.
