I just found this site. And this thread. Am enjoying it all.
Yes, the
Strand archive site shows the MMS in 1973 and tags the Compact
line in '75/'76. The Compact was MMS guts/modules built into a different 'box', w/wheels. I hired into a
regional theatre in '79 and they/we had a Compact 200, in Michigan. The story was it came over from UK to assist the '76 Montreal Olympics. Then we got it used!
I kept the beast going for another 10 years. The handwired
console had a lot of simple pressure fit
wire connections. An insulated
wire drawn down into a slit makes contact. The sockets that the
circuit boards mated into were all like this. It all loosened up with age and things started happenin'! When things started blinking, ya'd hit it on the side on the
masking tape "X".
Plus, there were
power supply issues, batteries (with about a 2yr life) soldered onto a
circuit board, and having to run a 150Q show with just the
pin patch Subs (with a helper repinpatching the subs as the show ran) because the memory went away.
The Compact 200 was my first memory
console. I came to it after 7 years with an ol' Izenour Thyratron 10 scene
preset. That's another whole story.
Uphill in the snow!
