An aside...

The automation machine at one station I worked at had 2047 programmable steps. (well, 2048, 0 was a step)

As a 16 year old, I could not fathom why it was not 2400. With 2400 steps, you could program each hour the exact same; not so with 2047.

Editing was a dream on the ASR33 teletype. Seems scissors and tape are very effective.
