Good hear it stood the test of time! As an HP PC dealer in the 80s into early 90s we ha a calculator contract with HP also and... we sold the heck out of them! Is it the only one of the 10 series calcs that stayed in production? I have a set of the special demo versions that were mounted on a descriptive plaque that had been in the PHX HP Corp demo center... when they redid that they knew I Hoarded stuff and sent them over. For some of the 10 series that were still being used we had them on the display floor the others went into the the suites next to the business in the historical display.

There's a Swiss guy who's made a name for himself by producing working replicas of classic HP calculators. See https://www.swissmicros.com/. I recently discovered his post on Youtube a video showing off an enhanced replica of my favorite HP calculator, the HP42s. This one is called the DM42.

OT: PCI Ethernet or USB 2.0 ethernet?

by w2hx＠w2hx.com

Friends, I have an instrument that has an intel motherboard with 400 MHz FSB PCI (not PCI-e). It has a 100 mbps Ethernet card and it would be very useful to get faster networking. The chassis of this instrument is such that I cannot fit a traditional PCI 1GB Ethernet card (I've tried). So I will have to go wifi (which I can make fit because I can remotely locate the wifi antenna). I have 802.11ac both 2.4 and 5 GHz available. While it certainly won't get as good a throughput as a dedicate GB Ethernet card, this is my only option. The question is, whether you think I would be better off using PCI wifi card or a USB-wifi adapter. I should mention the USB on this instrument is USB 2.0, the spec for which claims up to 480 Mbps. Anyone have an opinion which might get me better results? The wifi infrastructure is one constant in this scenario, just looking to see pci- or usb-based wifi card. Since this is wildly off topic, please respond to me directly so as not to bother everyone else :) W2hx at w2hx.com<mailto:W2hx at w2hx.com> Thanks Eugene

Trip to CHM - Hotel/Restaurant Advice

by barythrin＠gmail.com

I thought the Vintage Computer festival west link might have recommended hotels but I couldn't find anything for you. I did a similar trip but needed to be quite a few hours south for my actual destination. I didn't find a very cheap hotel either, and the under $100 one I did find near long Beach was quite underwhelming. The type my wife wouldn't have let us stay at. What I did find more useful was a super small rental car for $98 that did give me much more freedom to get around a few sites (and Weird Stuff). ?It was highly recommended not to sleep in the car though so best luck. I explored airbnb but it seems to mirror closely to hotel prices and a surprisingly large amount want a 2 day stay. But CHM is definitely a fun trip. I have a quite large collection for home computing so I wasn't sure how long I'd stay occupied but between the demos and tours and just perusing I definitely could have enjoyed more than the afternoon I spent. Best recommendations were ubering or rental car then get a hotel in your price range but don't worry as much about location. Or get one near the train.

Trip to CHM - Hotel/Restaurant Advice

by rickb＠bensene.com

Hello, all, In mid-June, I am planning a trip to Mountain View for two days to visit the Computer History Museum. I plan on flying out of Portland early AM on June 14, checking into hotel, then heading straight to the museum for the day. I will go back to the hotel for the evening, and return to the museum on the 15th, and stay into early afternoon, and then check out of the hotel and head to the airport to return home. I haven't been to CHM before, and am looking forward to spending an extended period of time there. What I'm asking for is help/recommendations in terms of a good hotel to stay at that is relatively close to the museum. I don't want to be in a luxury hotel, nor do I want to be in a dive. I'd also like to be in a place that has a restaurant relatively close by (preferably within walking distance) that I could get some decent meals (breakfast/dinner) while I'm there. Unless this is a topic of general interest to the group, it'd probably be best to reply to me directly rather than post responses to the list. Many thanks, -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

WTB: DEC VR241 or HP 6000 670H (or 670XP)

by spectre＠floodgap.com

I'm looking for two items: A VR241 to use with my DEC 380 as a colour head (even better if you have the cable and a spare LK201, since I'm down to my last working keyboard). The VR201 isn't cutting it anymore and I don't think I can use my VR260 with this. An HP 6000 670H hard disk (the big one for the 300 series). XP even better, but I've done just fine with an H. Please include what price you're asking. Thanks! -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Communism doesn't work because people like to own stuff. -- Frank Zappa ----

Cross-talk square-wave?

Thanks for taking the time for that detailed message. I suspect, however, that Jon Elson has nailed it (thanks Jon :-); if that's what's happening, it explains why we couldn't understand what the devil was going on! > (You've mentioned both 470K and 270K for the R, could make a difference > to the analysis). Yeah, that was just a typo; going from memory. Noel
