5. wiring the ENIAC with a new program
ENIAC
1946
Mauchly and Eckert
stats:
3,000 cubic feet
30 tons
18,000 vacuum tubes
70,000 resistors
170 kilowatt power req.
~1 kilobit memory
approximate processing power of today’s
singing birthday card
but not a stored-program device

6. 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).

7. configure switches, run batch, output to tape
Sunday 17 March 13

8. 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.

9. preparing punch cards
An important by-product:
confetti . All
the chaff from all those cards
was just great to throw around
the dorm.
Sunday 17 March 13

10. 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.
we
So on the one hand,
were adapting
to the machines.
On the other hand, the
workings of the machines were
exposed, right out where we
could get to them.

14. at home, it’s still the switches – but what to do with it?
MITS Altair 8800
1975
One of the first commercially
available home computers.
You ordered it. You built it. You
operated it through front
panel switches.

visicalc
Dan Bricklin
1979
Finally people had a reason to
buy a home computer
(specifically, an Apple II): so
they could use VisiCalc, the first
spreadsheet.
