This is what (we think it is) a
Timex Computer 3256 prototype, since it have tenet and disk connections, dipswitches to
configure station number under tenet and a reset button.
This machine have two boards inside and the TC2048 case was made higher to contain the two boards.
One is a TC2048 with some components ripped off, and the other a board with a microcontroller and the Timex Interface for FDD systems. The machine was not yet booted, but it will be tested.
