The Series 16 computers were originally designed by Computer Control Company, which was then bought by Honeywell in 1966.
Series 16 computers were used in a wide range of applications. Many were used in computer control applications, and many educational establishments used them as general purpose computers.
The most prominent application of them relates to the origins of the internet. The DDP-516 was used as the basis of "Interface Message Processors" or IMPs that were used to connect the very first networked computers to the ARPANET.
The DDP-516, introduced in 1966, and the later H316, which has an identical instruction set, form the core of the Series-16. The DDP-116 is clearly the forerunner of these machines, but seems to have had a limited impact commercially. The DDP-416 appears to be a development that is off the main path for the Series 16. The H716 seems to have come too late to be commercially successful.
Thanks to Adrian Wise for this information.
About this computer, Mr. Richard Pearson said us:
The picture is copied from the programming manual of the second computer that I was associated with, in 1966. The Honeywell DDP-516 was chosen for its high clock speed (aprox. 1.1 MHz) and expandability to 32 K of 16 bit words. Card and paper tape readers were the initial inputs with mag tape drives added as the system development progressed. The final configuration included a hard disc drive the size of a large upright freezer. Assorted special purpose devices were controlled by this state of the art unit. This system was done for NSA by a civilian R&D firm.

Dutch gas transport company had a series of 316 systems as process control system, and one 316 to manage the gas transport until .. around .. 1983 I believe. One 716 system as development / training system.

Early 70'', i was working at Eindoven for Philips on a medical project called Medex for Breda hospital using a DDP 516 (my first job).
I was adding a disk file management system named ISOS (indexed sequential overflow splitting) to Olert 2 operating system.

"The best toy I ever found in GDR"
DDP516 cloned for KRS4200
In the early 70ts or late 60ts somebody has carried some boxes with electronics over the iron boarderline ...
In the eastern germany, GDR, in german: DDR, the guys of ROBOTRON reengenierd this arpa-net-"router" and build a funny nice toy driven by the operators mostly by a typewriter.
( papertape, drums, magnetic-tape also)
the best thing was the bootloading process, operated through the binary "console". Not so nice styled like the original, but with stable working buttons, - so if not in cold mornings the buttons were jumping around. But in seconds they were touched back ...
Very much fun, when the operating girls searching for the buttons around the mt-device and under the drum-section ...
But back to the facts:
KRS4200 has also rewritten opcodes: all the abbreviations stand for german words. So also was developd a "german speaking" BASIC.
In the middle of the 80 were so many "KRS" devices in the GDR, that a special hardware-emulator device emulating KRS was developed for the GDR - PDP11-derivat A6400 (This was the follower-device past KRS in the planing-economy of the GDR.). The result: my moonlanding game (commandline driven) was 10 times faster then on original KRS.
Today are only 2 or 3 devices in some museums. One you can find in "technische Sammlungen Dresden".
The guys of Halle-Computer-museum have some nice old pic of the device:
here some with a best looking DDR-folklore-sheet under the console:
