Yes.  The 11/10 has 1K read only memory, 128 words read-write core, turnkey
console, and a direct memory access channel.....a process control system.
Add a front panel and teletype, a little more memory and you have the
11/20.  I am guessing the 11/10's were embedded in stuff, they're probably
still out there but harder to find.  If you have a front panel model it's
probably the 11/20, or a (field) upgraded 11/10.
