Motorola MC68000 Educational Computer Board (MEX68KECB)

Introduced around 1982, the MC68000 Educational Computer Board provides a complete microprocessor system on a single small printed circuit board, including a 4MHz MC68000 16-bit microprocessor, 32KB of memory, 16KB of firmware, parallel input/output (I/O), and serial communications I/O. The user must only connect an RS-232C compatible dumb terminal and power supplies to have a functional system. The firmware, aptly named "TUTOR", provides the user with monitor/debug, assembly/disassembly, program entry, and I/O control functions.
