If I understand clearly, these boards were put out to make it easy for someone to use and/or develop for the microprocessors they wanted to sell.
What I find fascinating about them is that they are stuck somewhere between the control panel computer (no ROM) and a computer running a terminal based machine code monitor (ROM of some type) in that they usually have to have a ROM (of some type) to allow controlling them via a 4x4 keypad and often 7 segment displays.
