"Aren't these for more of what they can do, then for what they sound like. Basiclly, it gives a number of logic modulues to your banaplug modular.
After playing with my Nord Modular for a while, you get to really understand the power and flexibility of logic modules.
So the power is in what it does or doesn't do to your sound, rather then in it's sound creation abilty.
Though never played with one, so there could be some good sound making abilties.. i do see the diodes and tube...

Currently on the *bay. Title link takes you to shots saved for posterity. This looks like one of those educational kits. Read below for details. I always wonder what one of these would sound like. My guess is nothing too impressive otherwise they'd be more popular, but who knows... If you do, please feel free to comment.
Notes from the auction also saved for posterity:
ANALOG MODEL 652.A ELECTRONICS SYSTEM LAB
6 DC power supplies regulated with fixed and variable outputs with both positive and negative fully protected supplies; 2 phase AC power source; waveform generator with sync, fvco, variable sine, square and triangle outputs from 1 Hz to 100Khz; meter for AC or DC voltage and DC current shunts; high impedance AC input to prevent over-loading; switches, resistors, capacitors, inductors, diodes, zener diodes, varactor diodes, transistors, lamps, op amps, radio coil, transformer, digital and linear IC socket, vacuum tube socket, PC, printed circuit, or breadboard slot; FET's, MOSFET's, UJT, SCR, Triac, Diac, and built-in speaker.
DIGITAL MODEL 703.A DIGITAL SYSTEMS LAB
A/D converter, D/A converter, follower/hold, scmitt trigger, comparator op-amp, one-shot, variable speed digital clock, counter and register, IC socket, PC, printed circuit, or breadboard slot; multiplexer, demultiplexer, encoder/decoder, 8 electronic switches, 10 flip-flops, 4 AND gates, 3 NAND gates, 3 OR gates, 4 Exclusive/OR gates, 3 NOR gates, 6 Inverter/NOT gates, keypad, and built-in speaker.
CONSTRUCTION AND CONDITION
The Ed-Labs are well constructed 1/8" aluminum panels each housed in 23.5" W x 14.5" H x 10" D formica cabinets. These were purchased from a Vocational School surplus sale and were described as operational to the auctioneer. There were no banana cables or manuals included. Both power-up but are untested by me (no cables). These instruments are very clean cosmetically. Each has a foil serial number sticker on the front panel and the 702 has its serial lightly scratched in small numbers under the keypad. There is a ding to the lower left corner of the 651 (see picture). The 651 is also missing a knob on a button switch at the bottom labeled "M" and a knob in the radio circuit. This knob mounts on a shaft that is sitting flush to its front panel casing. The 651 was missing one of its rubber feet, so I replaced those with a similiar white set of four. The original set of three will be included with the auction. Both units appear to be otherwise complete.
APPLICATIONS
The Ed-Labs can be employed as expanders for a modular synthesizer system; for circuit design, modification, experimentation; or as effective tools for those pursuing a general electronics education.
