Anyone have any docs on Termiflex handheld terminals?
Hi, All, I recently picked up an item I've been looking for for quite some time, a handheld configuration "terminal" for a LeCroy 1440 HV chassis, called a "Model 1447 Local Diagnostic Controller". It's superficially like the DEC hand-held used in the field for internal RA81 diagnostics but it's not the same model. The 1447 is described in the 1440 docs, so I have the pinout (DA-15 with TxD and RxD on pins 2 and 3, plus ground and +5V on certain pins). A sticker on my 1447 indicates it's a "Termiflex" product but all I can find online are pictures and docs from the later LCD display units. This one has a 1x16 LED alpha display. Does anyone have any docs on older LED Termiflex units? Again, I have the pinout but I'm curious about the innards. Unfortunately, the 4 case latches are difficult to unlock without some magic shim tool or I'd just open mine and reverse-engineer the PCB (there are four 2mm x 8mm slots with some sort of metal barbs at the bottom that seem to need a specific tool to open - a small blade has been unhelpful so far). Pinouts (cf J3) https://prep.fnal.gov/catalog/hardware_info/lecroy/high_voltage/images/fig216.gif >From the LANL docs for the 1440 I've found so far, it's unclear at the moment if TxD and RxD are +/-12V or +5V and GND but that's easy to check on the TxD line before I put anything on the RxD line. Thanks for any info. -ethan
What connector is this?
I am looking for the mating male connector. Anyone that has an idea what connector this is? There is nothing indicated on the connector itself about what the manufacturer it is. https://i.imgur.com/YzAfB2g.png /Mattis

visit to Bletchley Park / comp museum - Elliot 803
Hi all - Gatwick Airport was closed for many hours. Without getting into all of the details it became impossible to make it to the museum during my layover. As it was everything had to be perfect. I went to London for a few hours instead. My goal was to see the Elliot 803 at the computer museum in Bletchley so I could learn more about how it worked, I found some code written for the 802, which would work on the 803, and I thought it might be worth the experience to see or maybe even operate the actual machine. There is no simH that I know of for the 802/803 but I have read some attempts at it. I realize I could not see the whole museum and would be rushed, but given I was only in London for an extended 17-hour layover, why not try? Peter Onion Elliott 803 Team leader was going to meet me. Thanks everyone for their feedback. I am going to try to visit next spring for a longer period so I can take my time. I also would like by then to try the same technique I used for the LGP-30 to get that running on simH, applied to the Elliot 803. I'd have to get my head back into that project. Complicated. Bill

Published on Jul 12, 2019 IWe finally are able to make the original erasable core memory work, under the watchful eye of guests more famous than us. This completes the restoration of the AGC. In the process we dump the historical content that was still present in the memory module and find all kinds of interesting things. Also, at 17:26 is that a HP 2116A in the background?

Just received notice of shipment. You know, the postage from Garland, Texas to LA, CA for a box of 88 floppies would have been more than $6.95. How much more, I don't know. Could they have made a loss on that transaction, hence the price bump? That's not the same BG Micro we bought stuff from in the early 80's, is it? bill The one with the yellow photocopied catalog? That's the same one. The owner/founder passed away a year or two ago and I believe his daughter is running it now. Will Can anyone estimate the likely US postage for that package? Please let me know. If BG Micro are badly out on that transaction, I'll contact them and make it up to them. Would not if it was some big corp, but BG Micro are clearly honest. Such a rarity. Funny, I was thinking of Diogenes and his lantern just the other day. https://en.wikipedia.org/wiki/Diogenes Without the exact zipcodes and weight, can't get exact postage. However, it is likely to be "zone 6", for which parcel post for 1 pound is $7.62. There are ways of getting some discounts, such as online ordering of postage, instead of the counter at the post office. A Priority Mail small flat rate box would be $7.50 A Priority Mail flat rate envelope is $6.95, but rather tight. So, the postage might be a LITTLE low, but not by much. I don't know how much the online discount is. I don't know how much UPS currently charges. I don't know how much Fedex currently charges. Plato defined "MAN" as "featherless biped". So, Diogenes handed him a plucked chicken. Plato refined his definition to include broad toenails. Plato said that Diogenes was "A Socrates gone mad". Nothing that Diogenes wrote has survived, so we rely on third party accounts, mostly by those who were adherents of others. Alexander The Great asked Diogenes what he could do for him. "Move over; you're blocking my sun."

Oh good, so it wasn't a loss for them. Thanks. Btw I emailed them and also asked what kind of quantity of those floppies they have, and would they do bulk deals at the original price. 'For a friend'. Still doing my best to keep driving the price up. :) >Plato defined "MAN" as "featherless biped". >So, Diogenes handed him a plucked chicken. >Plato refined his definition to include broad toenails. > >Plato said that Diogenes was "A Socrates gone mad". Plato was a humorless twat. Diogenes sounds like a really cool dude. Today he would have been a hero-level philosophical Troll. Perhaps a great leader for Gen-Z. Certainly Twitter and Facebook would have banned him, and Amazon would be working on hunter-killer drones just for Diogenes. >Nothing that Diogenes wrote has survived, so we rely on third party >accounts, mostly by those who were adherents of others. > >Alexander The Great asked Diogenes what he could do for him. >"Move over; you're blocking my sun." One of my favorites. I'd like to get a print of that Waterhouse painting, Diogenes, the pot, and lamp. Guy

Margaret Hamilton is well known in regards to the AGC, and as the article mentions she received a Presidential Medal of Freedom, amongst other awards including from NASA. She is not unknown, nor unacknowledged.
Re: Box of HP 1000 series MUX cards - 12040
Whats your deal dude? I'm not trolling anyone. I have hundreds of these boards here.. I don't need 170 HP 1000 Series MUX cards. They just don't sell that often for me to hold on to. What else do you want me to do with them. Its crazy that you are insanely upset that I cross posted on here. If you want working 12040, I have 87 more after those. We strip down system, build custom 1k boxes, sell parts, and buy parts.. kind of what we do. Not really sure how to respond to that but geez, get a beer.
Seeking documentation for Tallgrass Technologies "Shortcut"
Hi, All, Another recent find, a Tallgrass Technologies "Shortcut", 80286 upgrade for 8-bit PCs. I've found several reviews online but no docs and no software (to enable the onboard 16K cache). One thing that concerns me is that on this unit, the 24-pin socket at U18 is empty. It might be nothing. This one does not have the memory daughtercard on J1, so perhaps they are related. If anyone has docs or has one and could tell me if their U18 is empty (and if not, what goes there), that would be great. Thanks! -ethan
