I just finished adding some pictures of the core memory boards from the
UYK-20 to my website at <
http://www.classiccmp.org/hp/UYK-20/>. This
<
http://www.classiccmp.org/hp/UYK-20/back.jpg> is a picture of the back of
one memory card with a 3.5" floppy disk laying on it for size comparision.
This <
http://www.classiccmp.org/hp/UYK-20/top.jpg> is a picture of the top.
The core is under the green cover. Here is a close-up of the Sperry Univac
logo on the memory board. And finally, here
<
http://www.classiccmp.org/hp/UYK-20/core.jpg> is a picture of the core
itself. You can get an idea of the size of the core area in comparision
with the 3.5" floppy disk in the LH edge of the picture. The green over
comes off very easily. Just remove four screws and it slides off.
Lyle Bickley send me a couple of PDF files about the UYK-20 and I've
posted them on the same webpage.
