"VERY OLD ARP 2600. ONE OF THE OLDEST PHIL SCIRROCCO [Phil Cirocco] HAD SEEN WHEN HE WENT THROUGH IT AND MADE IT NEW AGAIN. TONUS LOGO... DIMENSIONS: 32" x 18" x 9x WEIGHT: 58 Ibs. THATS WITHOUT PACKAGING."
"I didn't know if the switches for the Jam Inputs would work with SPST switches... but the first one did, so I wired the rest up & everything works great!!
As usual Red = Output, Black = Input.... this is just a little frame / panel I use as a wiring jig but I'm really liking the layout."
4018 / 4029 Lunetta-esque Sequencer - Working!
"this is like a modular module... kind of a sequencer / clock / divider sandbox.
The top row handles interfacing to analog voltages; on the left is a simple comparator (In & Out) so any old voltage, LFO, Envelope etc. can be used to drive the CMOS chips. The next 5 bananas are a simple, single op-amp R2R digital to analog convertor so the outputs of the counters can drive a VCO etc.
The bottom row is the CD4029 , with a clock & direction input - the latter is really cool & can be used to 'loop' the counters.
The two middle rows are the in, out & controls for the Divide by N Counter. I have set-up switches for the Jam inputs so a pulse on the Preset Enable input with set the output states according to the switch settings making it a little like a regular sequencer but with the"

"a salesdog rings it's bell to drum up sales of the daily rag. his sound is run into the Buchla 227e's envelope detector to provide the base control voltage that drives the entire system. all sound is generated by the 200e electric music box / modular synthesizer."
