While scouring the web for leads on classic computers, I came across a VERY interesing listing of items for sale, to wit: MINUTEMAN DIGITAL COMPUTER. General purpose synchronous, serial, digital computer originally used to solve inertial guidance problems. Mag disc memory 2688 words of 27 bits each. Clock speed 345.6K/sec. Pwr: 28V DC, and 115V, 3 Ph, 400 Hz. Mfr: Autonetics. DATA PROCESSOR. Includes tape reader, punch, and display. Mfr: Control Data 8090. DIGITAL COMPUTER. Cabinet mounted with memory core, and operating panel. Pwr: 115V, 60 Hz. Mfr: Digital Equipment. PDP-5. What I wanted was the PDP-5. I called these guys up, identified myself as a vintage PC collector, and and spoke to a gentleman named Doyle. Unfortunately, the PDP-5 has been sold. I inquired about the 8090, but Doyle didn't know immediately whether they still had it, and I wasn't prepared to make a serious offer for it. The 8090 is a variant or derivative of the CDC 160A, but that is all I know about it. Anyhow, here is the info for anyone who is interested: Radio Research Instrument Co., Inc. 584 N. Main St. Waterbury, CT 06704 USA Tel: 203-753-5840 Fax: 203-754-2567 http://www.radioresearch.thomasregister.com Look under "Test Equipment/Computers". Their primary line of business is secondary-market sales and service of military-grade radar equipment. Some of the stuff listed on their website is wild, and I'm sure you've got to have the approval of a few federal agencies to buy it... --Bill
