Norpak was a logic device that used only 'NOR' gates. It preceded the PLC concept. The gates were hardwired. Since any logic function can be created using negative Boolean operators (NOR or NAND) they were usable for solid state control systems in place of relays. We used a Norpak system at the San Francisco International Airport on a plane fueling system in the middle 1960s. They had 10 NOR gates per module, and we wired modules using something like #20 AWG wires with some kind of termination on the end that could be inserted into the Norpak units. One had to be very careful using the units because after the various functions and their arrangement had been designed there were often redundant gates in series that could be eliminated, but this caused transparency of design to be lost. I was working for the Standard Oil Company of California in those days down on 225 Bush Street. Reid C. Allen, P.E.

govliquidation.com raises minimum bid from $50 to $150

by legalize＠xmission.com

Has anyone else noticed this? For all the items in Utah being auctioned, the minimum bid is now $150. That moves most of the stuff out of the bargain category, IMO. $150 for a 20 year old oscilloscope in unknown condition with no probes or manuals? I can do better on ebay. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

3b1 / pc7300 restoration

by dgriffi＠cs.csubak.edu

I pulled my pc7300 out of the garage and am attempting to get it to a working state. So far, so good. Except that the keyboard appears to be broken. Several keys don't respond. Some that do respond seem to have broken springs. Does someone here have a spare keyboard for a PC7300 / 3b1? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

COBOL Poster

by silent700＠gmail.com

I've finally gotten around to photographing a poster I've had for a number of years. Hoping it triggers some memories for at least one person here. I'd love to know who made it, when and most of all *why*: http://flickr.com/photos/chiclassiccomp/3037313448/in/photostream/ It's fairly large, maybe 3'x5'. It's actually textured - all the white areas are printed with some sort of coarse sand or grit. Right above the lower brown bar is written in pencil "A New Language" and signed, as far as I can tell "D. Meeny." Googling this info has turned up nothing for me. This was some serious work. I'm not one to question an artist's muse - but someone, somewhere, at some time, sure loved them some COBOL.
