MARF making



I repaired a MArF a few years back, but nothing was like the undertaking of getting the 248-3206 from the Buchla garage sale working. I only know of a couple of these in existence and I don't know that any of them work. Someone bought the panels with only the motherboards attached. I have had them in my possession for more than 2 years. I had to design, assemble and troubleshoot the input board and 3 output boards for this beast. Each board is 14" x 6" or so, no small task. Today it worked for the first time.

Pictured is the working MArF as a reference. and the 2 panels from the double size expanded unit. A 3206 is a normal 1602 unit with an additional 4 space panel added to it. The expander adds another 16 stages of sliders and memory as well as 4 more output channels. The 6 total output channels can address the 32 steps in any way. This thing could be a 200 system's only source of modulation generators. LFOs, Envelopes, Sequencers, Quantizers, Voltage Processors are all possible. More infos to come.

Much more info to follow.

I believe they sold that off only seconds after they took that picture. I don't know if it works.
