One solution for a quick and easy way to test prototype chips was the potbox, built by Lloyd Watts in Carver Mead's group at Caltech. The potbox is so named because of the array of pots (potentiometers) that provide bias voltages by tapping off the power supply.
I have written up plans for a slightly enhanced potbox, one which has been serving Dr. Godfrey's analog VLSI group at Stanford for the past several years. The design is written up here: Potbox paper.
