===Internals===
4B2E switches are the majority of switches used, with the exception of stabilized keys using two switches, a dummy switch and a regular switch weighted at half of the 4B2E switch. There are 10B2E switches present on the caps lock and shift keys, which interact with the latching mechanism. The caps lock key will latch when pressed down, and release when either of the shift keys are pressed. The 10B2E switch has a tactile feel on the shift keys, while all other switches are linear.

The switches are soldered to a one-sided PCB, and clipped into a black painted steel plate. The plate has multiple cutouts for screws, and the same design may have been reused for other keyboards. The plate is secured using metal standoffs and four screws into the bottom half of the case. There is a speaker present, possibly to provide audible feedback while typing. The PCB also appears to have been designed by hand, as the traces are not at strict angles and are instead wavy and natural.

The keyboard terminates in a 16-pin female slot connector that is keyed. The cable is flat, and is slotted into the PCB.
