28. front panel switches
DEC PDP-8
TI 980
1960’s
The internal architecture of the
machine is exposed in the
controls. You can see that the
PDP-8 is an octal computer,
with its switches in three-bit
configurations (it takes three
bits to count from 0 to 7, for a
total of 8 numbers. Base 8.
Octal. Get it?). The TI 980 is a
hexadecimal machine, with
switches in groups of four. Using
the switches, you program the
machine one word at a time (a
word being, say, two
hexadecimal bytes for the TI).

30. batch processing: feed it cards, wait while it runs
What you used to do
punch a deck of cards; take
the cards to a little window,
hand them to the operator; she
puts them in line with everyone
else’s jobs; when it’s your turn
she puts your cards in the
hopper and pushes “RUN”; your
program works or it doesn’t; an
hour or twelve later, you pick up
your cards and (hopefully)
printout at the same little
window.
What you do now
double-click an icon, see what
happens immediately.

31. preparing punch cards
An important by-product:
confetti. All the chaff from all
those cards was just great to
throw around the dorm.

32. preparing punch cards
Each key press punches holes,
so there’s no “erase.” Fixing a
mistake almost always required
ejecting the card and starting it
over.
In a pinch – say you really
needed to fix a card and the
punch was down – a clever
operator might know enough
about the card encoding to
close some holes with tape and
open others with a knife.
So on the one hand, we were
adapting to the machines. On
the other hand, the workings of
the machines were exposed,
right out where we could get to
them.
