It was essentially Baudot on the way in(some special char diffs) then
shifted to numeric on the way out. As I remember the shifted numeric was not
any of the existing Baudot variants. Alpha Stock symbols in and numeric
stock quotes out. If I remember correctly the first 2 chars selected a head
on a magnetic drum and then waited for the last chars match on that head.
Every user just had a new card plugged in. Reponses time was not user
dependent. 1 user or 1k users. A query just had to wait for rotational
latency.

the mid 90s. It used different codes for requesting/receiving quotes because
2^5 is only 32 possible characters. Alpha in/numeric out.
They created a *new* five bit, shifted code, rather than just using
Baudot????
