3.1.3) What speed upgrades are there for Atari program recorders?

Numerous methods were created for upgrading the (painfully) slow data
transmission speed of the Atari program recorders.  Most of these originated
in regions of the world where program recorders were normally used with the
Atari rather than (extremely expensive) disk drives.
