Bootstrap loader? I had to toggle in the whole freakin' program through the
switches and pushbuttons that weren't even _debounced_!
(Scelbi 8H, 8008, mine had 256 bytes of RAM)

We programmed the bootloader by soldering diodes in a matrix on a
circuit board. Diode present meant a one, diode absent meant a zero.
This was the PROM of the day (SEL 32 computer, early 1970s)

You worked for SEL ? I worked for Interdata.
