Overdrive for UNIVAC I

Peter Z. Ingerman comments:

‘… if any readers of this comment would care to chat about UNIVAC, I’d be delighted to hear from you. In particular, I’m looking for documentation on something called “Overdrive”, that modified a UNIVAC I to allow (under some circumstances) to have three instructions per word, rather than two.
