Product Overview
Archer catalog number 276-1983 is a 28-pin wire-wrapping integrated circuit socket designed for point-to-point breadboarding and prototype construction. Distributed by Radio Shack, this wide dual in-line package socket accommodates standard 0.600-inch row spacing microprocessors, EPROMs, ROMs, and peripheral controller chips. The extended square-profile termination posts provide the four sharp corners necessary for reliable, solderless modified wire-wrap connections.
Key Features
- Standard 28-pin dual in-line package (DIP) layout
- 0.600-inch wide row-to-row contact center spacing
- 0.100-inch (2.54 mm) pin pitch along rows
- Long square-post wrap terminals
- Open-frame dual-beam plastic housing for component cooling and board inspection
Applications
- Restoring vintage 8-bit microcomputers and wire-wrapped S-100 system boards
- Prototyping logic circuits and breadboarding microcontroller projects without dedicated PCB fabrication
- Installing 28-pin wide DIP memory chips, microcontrollers, and UARTs into wire-wrapped card cages
- Building bespoke synthesizers, modular audio gear, and hobbyist computing hardware
Frequently Asked Questions
What row spacing does this socket accommodate?
This socket has a 0.600-inch spacing between the two parallel rows of pins, designed for standard wide-body 28-pin DIP components such as microprocessors, EPROMs, and interface controllers.
What post style does this socket feature?
The socket features long, square-profile wire-wrapping posts designed to accept standard 30 AWG Kynar wire wrapped using manual or electric wire-wrapping tools.
Can narrow 0.300-inch DIP chips fit this socket?
No. Narrow DIP chips require 0.300-inch row-to-row spacing, whereas this socket is built strictly for 0.600-inch wide-body packages.
Nothing captures the hands-on feel of early computing like the snap of a DIP chip seated over rows of neat wire-wrap posts. Ready your wrapping tool and route your buses with genuine period-correct hardware.
