| Bendix G-15D Computer | ||
| Two Bendix G-15D general purpose digital computers were
installed in Hydroplot. These computers were presumably used in
the onboard production of bathymetric contour charts. These computers are not known to have been electronically interfaced with SASS or any other shipboard system. |

A product brochure, dated May 1964, for a Bunker-Ramo 133 Computer System.
The 133 looks almost identical to the CP677, and has (from the best of my
memory) very similar specifications. The CP677 was installed on the TAGS during the 1963 yard period as part of SASS and the AN/BRN-3, so the time period is about right. |

| NAVDAC was an acronym for Navigation Data Assimilation
Computer, which describes concisely what the equipment was, and what it did.
It's unusual for an acronym to end up being so precisely correct! It
was a general purpose computer which ran a
program that assimilated navigation data.
The original NAVDAC on the T-AGS was a Sperry computer built to a UNIVAC design. See the excellent commentaries by John Prough and Jack Keenan. Photos of the computer, which unfortunately do not show the face of the control console, are here and here. The computer consisted of the two three-cabinet stacks seen in the photo, one behind the Sid Mitman on the left, and the other behind LCDR Hammer on the right. By ca. 1969-1970 the Sperry NAVDAC had been replaced on the T-AGS by the Bunker-Ramo CP677. |

VOLUME
I OF II![]() This tech manual is the "final" version, published in 1962. There was a "preliminary" version which was all we had back in '62 when I was on Dutton. If memory serves me, the final version was just a reprint of the prelim! There were two major modifications to the Mark I in later years. These were the addition of a stepping magnetic tape recorder and the modification to the input and output units to provide communication with the Sperry SINDAC computer (MK3 SINS) and possibly other navcenter systems. To my knowledge, there was never a formal "change" to the tech manual to incorporate either of these mods. The only information I have for the first mod is an informal "installation manual" for the tape recorder, which includes instructions for the modification to the Mark I. I have this because I designed the mod and wrote the manual. As for the second mod, I do not have anything more than some pictures of, and technical information for, the "Sugar-cube" components used for the new Input/Output Unit logic circuits. I was not involved in the design, development and installation of this mod. |
