I guess that conversation took place before I joined. Could someone tell me - briefly - what the digitizer is good for? And what else would one need to go with it to make it useful? P.S. I recently

Hi A heads-up for anyone wanting a 7912 digitizer that we were discussing on the list a few days ago. There is one listed on eBay, item 1690813203 with a $19.99 start bid. It weighs 70lb, so it is not

Oh, Micronta, you better Boonton up your coat before you lose your Heath. 10-4 and "Put the Hammarlund" good Bally, Don (oops, went too far again!)

What a Fluke! My wife says "GR . . . GR . . . GR ! I want you to Packard all this junk up and Hewlett to the landfill! And do it FAST with your Jetronic!" I immediatly came down with a bad case of the

Dear Tek friends, Yesterday, after an interesting logistics operation (involving a 18 wheel truck, which transported the unit to a meeting point in the middle of a highway), I finally got my LA-265A

Mathias, The AM502, 7A22 for 7000 and 5A22N for 5000 look as if they are the same differential amp packaged differently. Many Ebay sellers are unwilling to ship overseas because of the extra

Don: Are you sure that you are not the guy I have been looking for to take over restoration of all of the 4000 Series products I have here? That part of Tek history is in danger of being lost forever

The 5000 series scopes are simple and inexpensive and are very useful. The low speed ones include normal, single and dual beam storage, all with large screens. There is a good selection of plugins,

Hi Everyone, I've previously posted an article on storage tubes originally published in 1953, I suspect it was Hughes technology but not certain. It can be seen at

Don, There is a Lemo USA Inc., somewhere in Santa Rosa, Ca. I do not think there is any manufacturing there, that must be a Swiss variation on the theme of Tekintag (Tektronix International AG). They

Now that you mention it (and I thought about it earlier but I don;t remember enough to hold an intelligent conversation) we were given the analogy that the screen was like a multitude of small

There was actually a storage tube prior to 1961. The first F-4 Phantom II was flown in 1958 and the radar scope was a DVST (Delayed Vision Storage Tube). The image would pretty much stay on the screen

Sorry for the confusion Lynn. I was referring to your description of the mechanical polarizer lens used to dim the display. Rotating one of the lens to control the light attenuation is analogous to

I checked with my copy of Pete Keller's book, "The Cathode-Ray Tube Technology, History and Applications". He says write-through capability was added to the T4014 in 1978. And, "Color write-through

Lynn, What you describe is also how liquid crystal displays work, except the LCD material is what rotates the light. The latter is controlled by an applied voltage, with the LCD material sandwiched

Just to add from Pete Keller's book, "The Cathode-Ray Tube Technology, History and Applications", he refers to the "Anderson bi-stable, direct-view, storage tube developed by Robert Anderson of

Hi Dean, I think the two color DVST came later (post 1976-77). When I first saw the 4081, it was green on green, as were the Battlestar Galactica shots (sorry, don't have either the pilot movie or the

I believe the manufacturer of the 4 pin plug Dean refers to is LEMO in Switzerland. Beautifully machined metal parts (reminds me of a fine watch) and gold contact pins. Pulling on the outer shell

I think there were two versions, with the 4052/4 version accounting for the increased speed and taking advantage of non-store which IIRC did not exist on the 4051. Definitely no orange write-thru. I
