"Second system unit with powersupply,analog tape deck interface and memory systems.
This system was installed in the Music Technology Labs in the mid 80s, where it was used extensively by the advanced studio users. It was purchased by the UW in the 70s. When it was purchased all the modules worked, including the digital keyboard. The system was removed from service in the early 90s, and has been in storage since. This two panel system has dual power supplies, keyboard interface, and is pretty amazing. The power, some control voltages and triggers are routed between modules in the back via a ribbon cable/movable socket system, so you can rearrange the modules and recable the result. The modules typically have a daughter card housing the active circuits which are mounted on a locking pin system. The system has been disassembled, each module has been packed in bubble wrap, and the cases with attached supplies are crated. The cost included shipping in the continental USA.
