These have a label on the back that says print control board. Approximately 1987 vintage
They contain the following main ICs:
OKI M80C85A-2 CPU
OKI M81C55-5 (or variant) 2Kstatic RAM with I/O ports & Timer
OKI M82C51A-2 USART (or variant)
Hitachi HM6116P-3 (or variant) 2K x 8 SRAM
Hyundai HY27C64D-20 (or variant) 8K x 8 EPROM
The board has several power transistors capable of driving a wide variety of loads, such as motors, coils, lights, etc. It would make a great robotics controller
Uses +5V and +12V power.
Includes full schematics (hand drawn) and memory map diagram.
a larger image can be seen here: 8085 Board
It should be assumed that the board has some unknown defect. I have Read-tested the EPROMs and they test good, with original code in them.
There may be slight variations in appearance from the one shown
I have 8 available. 5 include EPROMS, 3 are missing the EPROMs
I'm asking the following prices:
$9 (with EPROM)
$8 (without EPROM)
Shipping in the US is $4.00 per board priority mail, or $3.00 first class.
International shipping at cost +$1, for 8oz weight. |
