"Up for sale, a very unique and elaborate early 1980s synthesizer of mysterious origins. Due to the lack of resistors, capacitors and other circuit elements typically found in analog synthesizers, we believe this is very likely a primitive digital synthesizer. This mad scientist's laboratory of knobs, switches and multi-colored "spaghetti" wire is clearly a prototype or Mensa scholar's tinker toy, leaving very few clues as to who made it and for what purpose!
Featuring an array of discontinued and valuable chips, this synthesizer needs to be connected to at least one of the pictured multi-pin cables to produce sound, although we lack the tools to properly plug in or test this keyboard. This keyboard is being sold as-is, with no returns as we can make no claims as to the working condition of the unit and offer no assistance to the buyer on how to properly restore or operate it.
The enclosure features stylish hardwood ends like your favorite Moog or ARP and all of the wiring is extremely meticulous and elaborate. We've dubbed it the Jackson Pollock of wiring jobs!
Several of the main varieties of chips found in this synth sell for $10-20 on their own and this unit has great value in parts alone! Here's a rundown of a few of the more notable chips in the synth.
Toshiba TMM2016ap-10. This chip is SRAM (static RAM). Programmable and non-volatile (won't erase when turned off). More expensive than common DRAM and used in military applications in addition to synths, etc.
AMD EPROM AM2732DC - Erasable Programmable Read Only Memory - Potentially involved with sound shaping and preprogrammed sounds
Intel D273284F2 - another EPROM; same as above
NEC D70116C - This is likely the CPU microprocessor. This may be the brains of the unit.
2732 series chips - based on Texas Instrument designs. Used in speech synthesizers..."
oh my gosh! where is this synth now? Would love to buy for a film. Kyle at alarmist dot CO
