Also remember the dead simple strobe/ack protocol on the "centronics" parallel
printer port:
place 8 bits of data on output port
Wait some period of time for signals to settle (usually a simple counter)
Assert STROBE
Wait for ACK
Deassert STROBE
Wait for !ACK
and repeat until done ;-)
10 bit interface, guaranteed flow control.

Strobe: As derived from stroboscope. To briefly make information visibl
In optics or photography a strobe (flash) briefly illuminates an otherwise dark scene.
In digital electronics a strobe briefly gates signals onto otherwise idle lines.
