General Information
The RCA Microboard Systems were used in different applications, I have been told some of them are still in use on Oil rigs in Alberta, Canada and were also used in Austalia to control space tracking and communications hardware. The manuals: RCA Microboards, CDP18S600 and CDP18S603A
