PW did an Analogue Computer  project in the late 70s early 80s AFAIR.
It used three 741 op amps and lots of 2mm sockets.
Worked rather well - favourite was to set it up to simulate car
suspension hitting a kerb and varying the damper viscosity pot.
Output was on oscilloscope rather than voltmeter.
You could probably get the relavent copies fron the National Library at
Boston Spa.
