* Dual audio tape recorders (I never got them running for digital).
*Paper tape reader. I built the case for it from a aluminum chassis.
*Control panel. At the time all computers had a control panel - none do now. With the control panel I could enter the boot routine, inspect individual memory cells and make changes as necessary.
* Below the shelf was a paper tape punch and below that a power supply control consol.
*The teletype is a surplus military that ran at a blazing 110 baud.
behind the rack is my Heathkit ham radio with a kilowatt amplifier right behind the teletype
