I found an IBM PC/AT (for spare parts for another
recently acquired one)
with a small card placed in between one power supply lead to the
motherboard. It also has a lead clipped to the motherboard, presumably
to insert modified clock frequency to the 286.
On the board it says "Megahertz Corp (c) 1986 286-2 REV 4". The board
bolts to the back of the chassis and has one button (reset) and two
switches (6MHz-Turbo and rotary 8-9-10-11-12).
I had always wondered why Megahertz, who I only knew as a modem company,
would chose such a name -- now I know.
