Ed Thalen, Frank King and Bill Flora have been working on a problem with the German machine. A very little used instruction "Branch on printer busy" did not work. After tracing the ALDs, they found and replaced the failing card.

I am sure the fact that the German machine cannot load and execute programs has nothing to do with their fix.

Bob Edwards fixed a couple of mechanical problems with the IBM Transmitting Typewriter.

Bill Newman, Doug Martin, George Ahearn, Jim Hunt and Stan Paddock worked on wiring the switches in the typewriter.

Bill Newman and Stan Paddock tested the wiring and made some corrections. The typewriter was connected to Bill's Arduino. All of the typed characters sans two worked!!!

Next week the last of the special switches will be wired and tested and then wiring of the solenoids will begin.

Joe worked on both the second and third tape drives of the German machine. Test will be performed next week.

While it may look like they are working on the typewriter, Bob Edwards, Judith Haemmerle, and Bill Williams are working on a 'Williams' tube prototype.
