- Since all of its functions are implemented in hardware -- and I mean,
- in *hardware*, as in the finest Schottky TTL money could buy a decade
- ago, this would be a tough job. You are looking at Lear-Siegler's
- followup to the ADM3A, a vintage piece of computing gear so beloved
- that it has its own newsgroup, alt.religion.adm3a. (In fact, you
- might try posting your query there, as many ADM3A afficianados
- may be found there.)
-
- Count your blessings: you have a terminal that handles lowercase
- *without* the necessity of installing the upgrade kit. ;-)
- ADM's are also pretty hard to kill; I once bounced one down
- a flight of stairs, and it worked just fine afterwards.
- They also possess the same flowing, graceful, eye-pleasing
- lines as a Volkswagen Beetle, another simplistic low-tech
- design which proved remarkably sturdy.
-
- The ADM3A, by the way, has nearly a perfect layout for a Unix keyboard:
- no weenie function keys, no silly keypad, no useless caps lock, and no
- arrow keys. What it does have is (1) a handy escape key, just to the
- left of "q", (2) a handy control key, just to the left of "a", (3) an
- easy to smack ^, in the upper right hand corner, (4) a decent ~,
- which is the shift of ^, (5) handy [] and {}, (6) handy _ (right of ;),
- and (7) reasonable handling of the rest of the punctuation.
- Compare this sensible layout with the unbelievably brain-damaged
- default keyboard that Sun ships with Sparc 2's these days.
- Unfortunately, the ADM5 terminals deviated from their streamlined
- predecessors by moving the control key to an annoying spot and adding
- a few useless extra keys.
