I've added some more pictures to my website. The first ones are of one
of the UYK-20 computers. These were made by Sperry Rand and are militry
versions of the Univac and use core memory.
<http://www.classiccmp.org/hp/UYK-20/>. The other pictures
<http://www.classiccmp.org/hp/millennium/> are of the Millennium
microproccessor tester that was discussed here a few weeks ago. I took
these pictures in a hurry and they aren't real good, particularly the ones
of the Millennium. It was in the back of a dark warehouse and the pictures
show it. One item of interest on the Millennium is the pullout drawer on
the side. It has the CPU and all of the CPU spcific items on it. In other
words, you can change it from an 8080 system to a 6800 system by merely
changeing that drawer. I have two of these and IIRC one is 6800 and the
other is 8080 based.

Joe,
What's "behind" the "open.jpg" panel - have you opened it further
to see the
internal boards, etc. This is an interesting find....
From a manual: "The AN/UYK-20(V), is a general-
purpose processor designed to meet the requirements
of small and medium processor applications in
shipboard or shore military facilities. The processor is
used in the CUDIXS, NAVMACS, SSIXS (shore
installations), and TACINTEL subsystems."

They use a crap load of these things onboard ship. If you search the net
you'll find dozens of references to them being used for fire control
systems, navigation, communication systems, cryptography etc etc.
Somewhere on the net is a photo of the radio room of one of the big
battleships (USS Missouri?) and you can see one in the photo.
BTW IIRC I found a date of 1968 somewhere on one of these.

Joe,

internal boards, etc.
Yes I've opened it further but I didn't have tools with me yesterday so
I didn't open it further then and take more pictures. Behind the panel is a
bunch of core memory boards and some other cards. I don't remember much
about the other cards but I have some of the core boards here at the house.
I'll photograph them and post the pictures later today.
This is an interesting find....
Yes, they are. I found several of these and some UYK-44s about a year
and half ago and never got around to doing anything with them. One was
baddly damaged and partially stripped so I took it apart for the cards. The
others appear to be intact.
From a manual: "The AN/UYK-20(V), is a
general-
purpose processor designed to meet the requirements
of small and medium processor applications in

Under separate cover I'm sending you a PDF that I got from ACM's Digital
Library. Since it's under copyright and I pay for the service to retrieve
these documents, I feel uncomfortable posting the manual to the list.
