WFL/DCP SPO

Supervisory Print Out

In the original MCP based systems one or more consoles could function as the "SPO", the system operator interface. Originally it stood for "Supervisory Print Out" in the early MCP but has become "Single Point Operations" service in current MCP.

SPO

In aii.biz, this is the uniform GUI for dominion operations management and it corresponds to a squeak image I distribute and support.

		The SPO would be associated with a particular Operator Display Terminal (ODT), by assignment in the NDL (Network Definition Language) sources for the machine controlled. The TD series (classic TD830 shown) were typically used in the seventies and early eighties. This image shows a lot of reverse video, they were normally white text on black, unlike the IBM 3270 "greenscreen".
The dumb terminal is actually in the keyboard. An "SR" station type with a more programmable microprocessor replaced the TD.
