The KI10 was the second generation of PDP-10 processors (themselves, exact re-implementations of the earlier PDP-6 architecture). It was built out of TTL chips, on FLIP CHIP cards.
It was the first PDP-10 model to provide paging in its as-shipped form, with 512-word pages. It was initially released in a single-CPU version (DECsystem-1060 and -1070); a two-CPU version (DECsystem-1077) was released later.
It was used in later DECsystem-10 models, running TOPS-10. Via a series of kludges, it was also possible to run TENEX on the as-shipped hardware.
A few documents refer to the KI10-based system as PDP-10I.
Busses
Although the KI10 CPU provided two each of memory bus and I/O bus connectors (Quick Latch connectors for the former), there is only one bus of each type; the two connectors are provided for physical cabling convenience (left and right of the CPU cabinet).
