For sale is a one-of-a-kind vintage custom wire-wrapped microcomputer prototyping board.

​Built on a classic blue Vector 3677 edge-connector board, this unique piece of 1980s engineering features a dense, hand-wired point-to-point backplane. It appears to be a custom 8-bit single-board computer or serial controller.

​Component Highlights:

• ​CPU: Hitachi HD46802P (Motorola 6802 compatible)

• ​Communications: Motorola MC6850P ACIA (UART)

• ​Memory: Dallas DS1220Y Nonvolatile SRAM, Hitachi HM6264LP-15 SRAM, Fujitsu MB8532 EPROM

• ​Power/Clock: Elexon DC-512 DC/DC Converter, Nymph 1.8432 MHz Oscillator

• ​Board: Vector 3677 Prototyping Board with gold-plated edge fingers.

​Condition (Please Read Carefully):

This board was recovered from an industrial electronics cleanout and is being sold strictly AS-IS, untested, and unverified for parts, reverse-engineering, or as a vintage display piece. Please review all high-resolution photos carefully.

• ​Visuals: The board shows typical age-related wear, dust, and tarnish on the edge connector fingers.

• ​Wiring: The rear wire-wrap network is dense, but some external jumper wires appear to have been snipped or are loose.

• ​We do not have schematics or the equipment to test this custom hardware. No returns will be accepted for functional failure or missing connections.
