Soo, I looked around, here's the number for the
Z1,
the first Zuse machine, 100% machanical.
area: ~ 4 m^2
weight: ~500 kg
power: ~1000w
memory: 220 bits (10 floating point words of 22 bits)
speed: 0,2 IPS (clockfrequency 1 Hz, and about 5 clocks for a multiplication)
this comes up to
45,45 kZ (kilozuse)
Quite an extraordinary number due the fact of real low storage and speed,
not so much of size and weight.
His next (real) Machine is quite different
Z3 electromechanical:
area: 6 m^3 (including operator desk)
weight: 1000 kg
power: 4000 w
memory 1408 bits (64 22 bit words)
speed: 0,33- 1,4 IPS (3 seconds per multiplication, 0,7 per addition)
51,7 kZ to 12,2 kZ
Nice numbers, but to much memory :)
His next machine, the Z4, although in size, weight and power
like the Z3 is already 30 times faster, barely gets around a
Kilozuse ...
I think your formula needs some serious tinkering. I think the lowest
number should reflect the most classic machine.
The Zuse 1 should come out to 1 Zuse as others have suggested. So by
this measure, the Babbage Difference Engine should come out at something a
bit less than 1 Zuse.
The Pentium III with 256MB and 10GB hard disk sitting on my desk should be
something in the TerraZuse range (or much higher).
We should also factor in user I/O. Machines that used front panels and
blinkenlights should have much lower (i.e. more classic) scores than those
that have keyboards and 16MB bit-mapped displays with 24 million colors
and what not.
