operation like LIB, LOAD, BURN, TEST, SUM or
COMP, which read the
PROM. When S4 is waiting for a command, or
performing any function
which does not involve reading a PROM, the
socket is "cold" - it
has no supply voltages. Even when the socket is
being addressed directly,
it is only powered-up for sufficient time to read the
data.<$IPROM;24
pin>
PROMS with 24 pins or 28 pins must be inserted
at the bottom end
of the socket - the upper pin-sockets of each side
should be empty.

Basic Concepts
<$IWYSIWYG><$IESC message>The message
ESC in the display means that
the ESC key was pressed during or before
execution; the previous command
was not completed or maybe not even started.
The ZIF means the Zero-Insertion-Force socket on
the front panel.
<$IKeypad repeating>The Keypad refers to S4's
45 keys. Key repeat
is automatic, when a key is held down. The delay
after the first
entry is longer than that after subsequent entries,
to prevent false
repetition. When data is being entered by
repetition, the flashing
block cursor changes to a steady underline cursor,
so that progress
is easier to follow.
