You can find the story here. I did a quick search on LM13600 here just to see what might come up. This one post on the KORG MS20 did. I did a search on LM13700 and this one post on the Salamandar synth came up. I'm curious what else used these chips."The LM13600 has designed by Bill Gross and myself in less than 5 minutes. At the time the Consumer Linear IC design group was training a new mask designer. We needed something with a few transistors for her to learn how to arrange them in a optimum circuit arrangement while using minimum silicon area."
Look at a Voyager's analog board.

ReplyDeleteI absolutely love the LM13700. The fact that there are 2 matched ones on the same die opens the way for a lot of wizardry.
