These are in via Soviet Space Child who had the following to say about them:

"I found these to be super fascinating. Both modules are very complex in their builds/engineering. The 291e on its own looks to be a lot more involved than a lot of modern day synths. Also it's pretty interesting how the 291e uses a discrete circuit through hole design, where as the 261e uses surface mount technology, even though both modules were designed at around the same time. In any case, Don Buchla was really a brilliant guy!"
