Bio from IBM 1401 Restoration Project

In 1941, at age 20, I joined IBM Minneapolis as a Customer Engineer. In Chicago, from 1941-1943 and 1946-1949, I serviced accounting machines (402, 403, 405 407) , card reproducers (512, 513, 519), calculators (601, 603, 604) and card keypunches (026, 029). During WW-II, 1943-1946, I was at the Naval Security Station in Washington DC, responsible for maintaining special card machines (797) used for cryptanalysis of war-time transmissions. During the Korean War, 1949-1951, I returned to the Naval Security Station, maintaining ERA 1101 (ATLAS) and ABLE computers. From 1951-1955, I was a CE for the IBM 701 mainframe at Los Alamos National Laboratory. From 1955-to-1984, I worked in San Jose's Custom Systems, which included installation of a dual 305 RAMAC with attached 407 printers for the 1960 Squaw Valley Winter Olympics (1st computer at an Olympics). Other projects involved the 1620, 1800, and 360/20 computers. Over the past years at the Computer History Museum, I've restored an 077 card collator and a 513 card reproducer.

Bob Erickson had purchased an old Teletype Model 28, with a stuck main shaft, figuring he could get it working again, and he did. Bob asked if I would scan his manual and post it so some fellow in Illinois could use the information. - And here it is -

Bob's "Manual" is a three ring notebook, about 1.25 inches thick, with about 25 fold out pages about 24 or more inches wide. Scanning the fold out pages, and stitching them together was "interesting". I tried 5 different free stitch software packages, and highly recommend Microsoft's Image Composite Editor. I tried it with out reading the manual (of course, I are a enjineer) and in 4 minutes it was doing wonderful work.

The manual had no tabs, so I divided it into 4 functional parts - sequenced as in Bob's notebook
