The KL10 was the third generation of PDP-10 processors. It was built out of ECL, on hex cards. It was the first microprogrammed PDP-10 processor; the design was inspired by Foonly's F-1
It was used in the DECsystem-10 models 1080 and 1090 systems (with an external memory bus, compatible with the earlier KA10 and KI10), and the DECSYSTEM-20 20xx systems (with an internal memory bus).
Like its predecessor, the KI10, it was initially released in a single-processor version; a two-CPU version was released later.
There was a single KL10 ITS machine, MIT-MC. It was later renamed to MX and was shut down in 1988. There was also a KL10 in the Stanford WAITS system.
