EV-4 Matrix was also referred to as the Feldman/Fixler Matrix.

Was EV-4 encoding / decoding any good. I don’t recall any sophisticated decoders with logic ever being released.

I used a EVX-44 back in the day but eventually moved up to a Lafayette full logic decoder. Sometime in the 80's I picked up three EVX-44's (probably on eBay?) and eventually sold two. I still have one NOS EVX-44 in storage - if anyone is interested, make me an offer I can't refuse.
