   Rare Motorola 6802 Classic Microcomputer Trainer:

$156.12

Yup, that's eight, not a five. The Motorola 6802 was the predecessor to the insanely successful 6502. This Motorola Memory Systems MEK6802D5 was Motorola's answer to the KIM-1, AIM65, or SYM1.

Community college surplus is a classic collectible, besides still being useful as a student trainer or an embedded interface. Includes 1K of RAM and 2K of ROM and a parallel port. Unit checked out and memory read/write has been verified.

Believed fully functional, guaranteed servicible. Includes optional wall wart. No docs, but operation is fairly obvious, and the monitor listings are easily read. Includes experimental breadboard area and on-board regulated five volt power supply.

Fifteen day inspection privelege (you pay all shipping).

Shipping weight : 7 pounds.
Available in quantity.
