Thanks to the generosity of donations from our visitors, the museum purchased a Canon DR-M1060 scanner. We previously had an older large capacity auto-feed scanner that failed. This new Canon scanner has some great features. It will scan both sides of the page in a single pass and will scan a page per second. The capacity is just 60 pages but it scans so fast that you have to continuously load the feeder. The other great feature is it will scan an 11" page up to 118.1 inches in length. While we don't have anything that long to scan, most service manuals have three page wide fold-out schematics and it will auto-feed and scan these very nicely. We recently scanned a 948 page 4200 Series Programmer Manual in very short order.
We recently put together a set of equipment and lessons to introduce students to the concept of waves and oscilloscopes and donated it to the Sherwood Public Library.  This will be part of their new Library of Things.

The museum crafted 15 pages of experiments using an oscilloscope starting with basic operations of displaying a signal on an oscilloscope, then displaying waves with microphones, a music player, and a function generator. A speaker allows them to hear the sound of the function generator and the timbres that the different wave shapes produce.

The equipment was donated by museum President Dave Brown to Jenny Swanson, Library Operations Supervisor, and Rachel Seltz, Adult Services Librarian. The museum hopes to follow up with some introductory classes. If you are interested in volunteering to help with student classes at the library please let us know.
Sharp-eyed viewers will note that none of this equipment is Tektronix.  The museum received a donation of Instek Oscilloscopes and Protek Function Generators from the closure of a local technician training program. This equipment is not as full featured as Tektronix and is more suitable for beginners since there are less controls and switches. We also have a number of additional instruments for future expansion to other libraries.
The Photo Of The Month shows Howard Vollum at his home organ. Howard was known for his love of good music and had a studio built at his home for his pipe organ.  Howard's organ was built around the former San Francisco Granada (Paramount) 4/33 style 285 Wurlitzer. Jonas Nordwall, a well known Portland organist is attributed to saying "Howard was better than average at playing the theater pipe organ. However, his reserved personality meant that he never performed publicly." After Howard's death the organ was sold to the Regent Theater in Melbourne, Australia.

Rodgers Organ Company was an early spin-out of Tektronix, being formed on April 30, 1958 by Rodgers Jenkins, Fred Tinker, and Bill Johnson. Howard provided a personal loan to help start Rodgers Organ and later provided space in building 74. You can hear Jonas Nordwall of Rodgers Organ playing Howard's organ on our Howard Vollum at Tektronix page.
Chuck Miller was an instructor in Field Training. Early on Sales Engineers were expected to be able to fully support customers with both sales and service. Sales Engineers were issued tool kits that consisted of the tools, transistors, and tubes needed for basic service. Training classes were held at the factory for six months of which half was devoted to troubleshooting techniques on the most popular products. These training tapes came later and were designed to be used in conjunction with the service manuals to learn troubleshooting.  Eventually the Concept Books were developed as part of the curriculum for Field Training.

We have digitized one set of his tapes on the 7704A circuit description. The Tektronix 7704A was a 200 MHz 7000 Series mainframe oscilloscope produced from 1972 to 1987. It takes two horizontal and two vertical plug-ins. These training tapes are meant to be used in conjunction with the 7704A schematics. There are seven approximately 30 minute files so the complete lesson is 3.5 hours of detailed training. You can listen to these files on the 7704A Circuit Description page.
The museum built and sold 300 of our demonstration boards which will display the Tek Bug, the Wizard, or allow you to play tennis on your oscilloscope. After selling 300 we retired this board but we still continue to get requests for it. Rather than continue to spend resources and time building the boards we will be moving forward with selling a "kit".
The kit will consist of a programmed microprocessor and the schematic to build it yourself. It is a fairly simple design and we hope this will satisfy the on-going demand for this demonstration board. We will be adding this to our eBay store as soon as we have an inventory of parts.
