AMF Educational Computer Model 665/D

YEAR: 1968
ITEM: Analog Computer
COMPANY: American Machine and Foundry
COUNTRY: U.S.A.
IN OUR COLLECTION: Yes

The American Machine and Foundry (AMF) Educational Computer was made in the late 1960's. This particular computer is probably from 1970.

American Machine and Foundry has existed since 1900 and has manufactured everything from tobacco machinery to lawn and garden equipment to sports equipment. Today, they only make bowling and billiards-related products.

This educational computer is built into a small wood case about a foot wide which is reminiscent of portable phonographs of the 1950s and 60's (including the hinges that allowed one to remove the top). The top of the case included a voltage meter, input jacks and a storage area for patchcords. The base included the computer and a small storage area for the power cord. A property sticker on the computer indicates that it was owned by PUHS...possibly from Phoenix Union High School in Phoenix, Arizona. (Imagine going to a high school with the initials "PU"...one can only imagine what the chants were like at their football games! ) Removing the faceplate from the unit, we discovered the schematic diagram inside which indicated revisions starting in 1970. An IC inside is also dated 1970.

We have found no information about this device anywhere online. We do have a few photocopies from a teacher's manual published by McGraw Hill in 1972, however they focus on programming exercises for students and do not provide us any information or history about the unit.

We are not sure when this computer was originally manufactured. We believe it to be in the late-1960's. If you have any information on this computer, please contact us.

       I used one of these when I was in high school in Connecticut in the early 70's, and now I have one on my lab bench at home. My unit isn't in quite as nice shape as yours, but it operates just fine. I've been able to replicate a lot of the simulations I did back around 1970. My next step is to build a few more modules to perform nonlinear functions like polynomials, etc. Any chance you can send me a scan of the schematic? My unit is missing that. Thanks! J...

       I was in a class in 1967-8 called Engineering Concept Curriculum Program. You can google it. We had rudimentary equipment like that.

       I have an AMF going up for auction on ebay 8-31-14 if any one is interested in owning one.
