#TIL Alles Machine (nick: Alice), developed by Hal Alles at Bell Labs in ~1977, the most powerful synth of the time, had 64 oscillators, 32 filters, 32 amplitude multipliers, 256 envelope gen., 30 kHz sampling rate, 16-bit DAC, 14-bit ADC, 255 timers, 16 FIFOs, 1400 chips, capable of additive, frequency, and phase modulation.
Entire system was controlled by a DEC LSI-11 in real-time using MMIO, with two 8-inch floppy disk drives. Development was done on PDP-11.
#TIL Why a variable resistor with a movable tap is called a "potentiometer"? It's not a meter and doesn't measure anything...
Apparently the "potentiometer" is an actual precision voltmeter that uses the principle of variable resistive divider. Later people started using the name for all adjustable resistors with a tap. https://en.wikipedia.org/wiki/Potentiometer_(measuring_instrument)
