The Archbold Speedup Board

The TRS‑80 Model I ran at a speed of 1.77 MHz. That speed was quite fast for a microcomputer at the time, but almost immediately people began designing speedup boards to increase it. The most famous of those speedup boards was the Archbold Speedup Board, designed by Bill Archbold and sold by Archbold Electronics.

The Archbold Speedup Board itself was a fairly small board (1.5" by 2.5").
