I checked my Osborne Executive Reference Guide. It lists starndard
hardware features:

Z80A central processor
124K total RAM
4K RAM for two charactersets (128 characters/set)
4K x 12 RAM for video memory
2K bytes scratchpad RAM
7-inch amber video monitor
Two double-density disk drives (185K capacity each)
Two RS-232-C serial ports
Parallel port: IEEE 488 or Centronics protocols
External Video connector
Composite video connector (RS-470)
Full upper/lowercase keyboard, with numeric keypad

The RAM is bank-switched.
