  1219 - Follow-on to 1218 by Greg Casey - 09/25/2008 18:43
I was in the Navy from 1972-1977 as a Data Systems Tech. After College, I worked at Sperry Defense Systems.

Well the 1219 was a Univac(Sperry) product, built for the USNavy. It was a follow-on to a 1218 product. It was also a leverage of the 30-bit CP-642 family of NTDS (Naval Tactical Data System) I beleive the 1218/1219 were 18-bit computers with like 16K words of memory.

Really cool pictures.

I was on DDG-2, a Tartar guided missile destroyer in the 70s. I maintained the Missile fire control system. We had two 1219s (Mk 152) that ran the system. Many late nights at sea writing fun but useless programs for this machine. Underway we normally kept one on line, and the other was free for maintenance (had to check all the op-codes :-). Great times playing with Million dollar "toys". (Not to mention seeing the world on a really cool "yacht"). I have written up what I can remember about the computer (and the missile system) in my computer history pages, on my web site at:

Anyone has any technical rememberances about this, the system, or the ships, add a post here, or drop me a line:

Thanks!

Scanned more docs related to the the UNIVAC 1219, also known by the US Navy as the MK 152 Computer.

  UNIVAC 1219 / 418 Models by Bill Degnan - 11/13/2014 10:32
If the 1219(B) and the 418 I/II are the same model they certainly look nothing alike.

As part of my ongoing doc sorting efforts I found the 418 Systems Description Manual and a lot of 418 III stuff. This will help me to poke around Duane Craps emulator when I get the chance, in addition to the info he provided.

Most of the WWW says that the 1218, 1219 and 1219B are simply militarized versions of the UNIVAC 418 I or II commercial models, depending on the delivery date of the unit to the Navy.

It is a little murky where the 1219 ends and the 1219B begins vs. the 418 I and 418 II. There were a lot of other models being produced at the time. No one says the later 1219B were NOT 418 III's.

From my docs the 418 II was a "minor release" compared with the 418 I or 418 III, but I'd need to do more research. For example the Auerbach Computer Characteristics Digest (1969) lump the I and II together, with the III separated entirely.

One could infer then that the 1219 and 1219B were essentially the same, only the options were different. The 1219 came with 4K RAM as the minimum configuration but I don't think you could buy a 4K RAM 1219B. Little stuff like that. I *believe* that the original 1218 was based on the 418 II, and then from there it diverged into its own unique model.
