ether^ra who is the men behind the wonderful blog ether^ra : visual arts, sound manoeuvring & arcana pointed me the way to an other interesting blog by Jason R.Butcher who has a very nice Buchla 200 that he put together over the years. He posted a new picture on his flickr page that shows a Easel like Haliburton case with only six Modules. He is not only useing Buchla 200 modules but also Buchla's 250e Arbitrary Function Generator which is, acording too the Buchla homepage a 16 stage function generator, featuring direct and immediate access to each stages' control and timing voltages. I think it is amazing that one can still, so many decades after the first Buchla was build, use the old modules with the new ones (even though sometimes you need too attenuate or amplify some modules).
The new setup that he is experimenting with consists of the folowing Modules:
Source of Uncertainty Model 266
Quad Function Generator Model 281
Quad Voltage-Controlled Lopass Gate Model 292
Dual Reverb / Equalizer Model 275
(which is quite a rare module and only one of two old modules
that do not fit in the new 200e boats, the other one being the
Dodecamodule Model 212)
250e Arbitrary Function Generator
Programmable Complex Waveform GeneratorModel 259
(which is probably the most expansive Buchla module that one can buy from the old 200 series
but a beauty it is)
Short Update: An anonymus user pointed out that "there are quite a few 200 modules that don't fit in a 200e cabinet
without modifications: 208, 248 ,227 ,296 (296 fits only in one position in
the 18 and 24 cab)"
