I have a couple of System 10 manuals.
The machine is described as "The System 10 is a multi-programming system
capable of executing twent independant programs... The System 10 utilises as
new approach, the is no executive program, all executive functions are
performed by hardware.
Each program is assigned a fixed block of memory referred to as the user
partition. A system 10 may contain up to 20 such partitions. In addition
there is a common partition shared by all programs.
Main memory is comprised of core modules of 10,000 locations, and each
location contains one 6 bit word. System 10 may contain a maximum of
110,000 locations.
The maximum partition size is 10,000 locations, and the common area must be
at least 1,000 locations. The max size of common is 10k in the Model 20 and
65k in the Model 21
Not much programming detail in the manuals I have, I suspect there was a
programmers guide also available.

I don't, but I did go to a job interview at a company in
Tiptree, Essex, England where they had one, in about 1988.
I read later that the Singer System 10 was an early RISC
machine, although it's not clear that Singer designed it
with the knowledge that making it RISC would make it
faster. It may have simply been a minimal CPU design that
came out RISC-like in hindsight. Anyone know any more
details?
