Jitter and Hit Synthesizer Model 2A

An iconic record label was once rumored to have spent a small fortune for one of these. Turn it on, crank it up and out comes a hit... or maybe just a jitter.

CES Ed-Lab 650?

2008-06-29T02:09:00.000-04:00

This 1982 Ed-Lab doesn't have a model number or name at the top. It seems like it might be a 650 based on what's on a 651.

This one has a speaker on the back face for a boombox feel. It seems to be a newer version of the 700 with added keypad and LED digits and no meter.

Notice all the multiple jacks! I was surprised to see any multiples on a banana jack system. I think a lot of the stock banana cables supplied with these systems were sort of economic and don't stack. There could be some potential educational clarity to using a multiple, but it seems sort of against the philosophy of banana patching.

This was likely pulled from a larger Comdyna 7000 Analog/Hybrid Computing System. The GP-10/S is still available from the manufacturer.

yes I have bananas

The Logic Lab just talked about did indeed use miniature banana jacks. In my quest for the elusive connector I wound up mistakenly buying a bunch of small full size banana plugs seen here. They weren't suitable.

I'm building some cables with miniature banana plugs right now. Actual Mini Bananas have a 3.05mm diameter vs. 4.3mm? diameter full size Bananas.

Does anyone know what the patch plug connctors that go with these jacks are called?

Update: mini-banana plugs.
