After going over the inside of the keypunch and bending various SMS socket pins and relay panel pins to ensure there are no unintentional shorts, the keypunch appears to be working just fine by itself. I finished wiring up the new keypunch cables I began with better, more secure connectors and larger gauge (lower number) wire. I dressed it well along the panel and made the cable much more bulletproof and production level.

SAC INTERFACE FOR ADDING PERIPHERALS TO THE 1130
I assembled more receiver and driver circuits onto the board today. I was able to finish one board and have three more to do. It is slow going to make sure I do it correctly. It has the +5V, +3V and ground power lines attached but does not yet have input or output leads.
|One completed board for SAC interface, 12 drivers across top and 12 receivers across bottom|
SCANNING COBOL PROGRAMMERS GUIDE MANUAL
Several manuals are not available on bitsavers or other digital archives, but should be. I slowly (and I do mean slowly) get the pages scanned in between other activities. This manual with more than 180 pages has taken three days elapsed time so far and I am still only at page 150. I don't usually comment on the scanning but realized it was completely sub rosa if I didn't.
