The most entertaining feature of Aquarius is that the tape is used only at
the outset, to set up the de-chi electrically, viz. on condensers : a charge
represents a cross: these are automatically recharged at least once every two
minutes, according to the rule "to him that hath shall be given".
The tape is marked at the 97th letter beyond the autopause and ( switch:
reading position, home, charge operating length, start reader) run backwards
through a tape-reader and so transferred to the condensers. It stops
automatically at the autopause, where its position is checked. Then (switch:
charge comparison length, start reader) 218 letters before the autopause are
similarly transferred. Switch: comparison length off, reader off, comparison
A set total is imposed on each counter (for /'s and 8's) and the machine is
In a position where the score on either counter exceeds set total, the
machine stops. The set total is taken off and the switch thrown to "rerun" (i.e.
count again without stepping). This checks the score and finds the score on the
To resume stepping the switch is thrown to "go on".
Because the text length increases, the set total requires occasional
(e) Impulse cut-out
Switches labelled 1,2,3,4,5 cut out these impulses, causing them to be
treated as all dots.
