<REFERENCE>PRIME>HONEYWELL
Prime's first systems were built to emulate the CCC / Honeywell Series 16 family of computers. That architecture lived on to the end of the Prime 50-Series as the S-mode instruction set and addressing conventions.
The first Series 16 computer was the DDP-116, designed in 1964 at CCC by Gardner Hendrie. It was intended to be a 14-bit machine, for cost savings, but during the design phase, IBM announced the S/360, pretty much setting a standard for byte size, and the design was quickly altered to 16 bits.
CCC was later bought by Honeywell, and additional models (316, 416, 516) were added to the line. The 316 and 516 models are most famous for having been used as the basis of the Interface Message Processor developed by BBN for the young ARPANET, first in 1969.
The SIMH package contains emulation for the H316. I have successfully assembled code in S-mode on a Prime system, then run it on both a Prime system and the SIMH H316 emulation unchanged.
A few CCC / Honeywell documents are here because of the connection between the Series 16 architecture and the 50-Series, and because it may be useful to compare them to Prime documentation for equivalent functionality.
More space is devoted to the Series 16 at several other sites, each of which are worthy of a visit:
- Adrian Wise's Honeywell Series 16 site.
- Philipp Hachtmann's H316 site.
- Theo Engel's DDPx16 Pages site.
- William Maddox' 3C Legacy Project site.
