KA10-based PDP-10 system

The KA10 was the first generation of PDP-10 processors (themselves, exact re-implementations of the earlier PDP-6 architecture). It was built out of discrete transistors, on short single FLIP CHIP cards.

B-series FLIP CHIP used in the KA10 CPU

It had hardware support for time-sharing (two modes, 'User' and 'Executive'), as well as base and bounds memory management hardware. These were used in the first DECsystem-10 models, running TOPS-10.

It was also the machine on which the ITS and TENEX operating systems were developed, after the machines were modified to provide paging.
