Duane Craps (from several states away) and Bill Dromgoole spent the weekend at our museum to work on the Univac. Here's a lightly edited version of their report: --------------- The 1219B is mostly operational It still has a few intermittent problems and a few we know about like a fan not operating below the memory chassis. We don’t have full communication with the 1540 tape drive but can transfer functional commands. We found a few bad cards in the tape drive but a lot more work is needed. We are able to load UPAK and diagnostic programs. We loaded and executed the memory test program but did not get a full 10 passes to get a good printout. After about 5 to 8 passes we get a program fault. We think due to overheating. We also were able to load and run “Hunt the Wumpus” game program. Here are some photos and videos. The second photo shows the broken computer with the main timing chain not working and some random lights lit. The eighth photo shows the parts at fault we found the first day. https://photos.app.goo.gl/Sauxna7fBda2OroU2 This link should work for anyone who thinks 640K is enough." ----------------- Related: Drom and Duane also served as museum docents. They reported a modest amount of visitors Saturday and tons of visitors Sunday. Said Drom: "It was so hectic I couldn’t give people as much attention as they wanted."
This is amazing work! Awesome! Sent from my iPhone

O U T S T A N D I N G ! This is the coolest thing I've seen in a long time. And the first time I've seen inside the CPU cabinet and seen the teletype operatie. Great job gents.
