Attendees: Ron Williams, Bob Erickson, Robert Garner, George Ahearn, Stan Paddock,  Frank King, Don Luke, Douglas Martin, Bill Newman, Joe Preston, Ed Thelen, Allen Palmer, Ron Crane, Judith Haemmerle
Guest: Bill Kell; My Father-in-law from Carson City, NV
 Having spent most of his career making computers and other electronics work, Bill had little trouble punching his name into a punched card on one of our 026 Keypunches.
Bill had a discussion with Doug Martin only to find out that they both spent considerable time doing support at the same over seas site.
It was a tape drive day. Allen Palmer continues on fixing the brake on the second IBM 729 for the German system
Joe Preston continues to work on the third IBM 729 for the German system. Joe has taken this machine from totally dead to being able to load a tape and I saw it writing data. Now if that data was good data ..........
Frank likes the IBM 1403 printer. When he heard a bad bearing in the IBM 1403 connected to the Connecticut system, he tore into it to get to the bad bearing. That is when he determined the bearing noise came from the IBM 729 directly behind the printer.  Frank found the offending bearings and is in the process of replacing the bearings with new bearings.
Ron Crane continues his quest to make the input power correct to the German machine.
While checking power supplies, Ron found the comment above written inside one of the gates. We are going to the CHM staff for a translation.
In our quest to find all of the problems with the Connecticut IBM 1402 card reader, we found one of the transistors  was weak. We found a match on E-Bay and bought it. The picture above is Bill Newman installing the transistor inside the bowels of the 1402. We have fixed several bugs in this area but still have at least one more to go.
Judith Haemmerle and Bob Erickson are working on the IBM Model 'B' transmitting typewriter that will be attached to the Connecticut system as an IBM 1407 inquiry station.
