Description:

Up for sale is a vintage custom-built microprocessor development and EPROM programmer bench unit. Enclosed in a hinged clear acrylic top cover with an underlying metal chassis, this setup features a main micro-controller logic board alongside a prototype breadboard/breakout area connected via dual ribbon cables.

The main logic board is fitted with a ZIF (Zero Insertion Force) socket for IC/EPROM programming, an onboard UV-erasable EPROM with a window, logic ICs (including Hitachi HD64180/HD74 series), a DB25 parallel/serial interface port, and an integrated 5V DC power supply box with a toggle switch, fuse holder, and attached power cord.

An interesting piece for vintage computing enthusiasts, IC programming tool collectors, or hardware restoration projects.
