I have purchased a few things from AMScope; two eye pieces, focus rack and a simple boom/base. The sale prices were fair, but I have seen better deals at auction houses (Dove Bid and the like, not eba

I have seen photos a few different times of a 465 with this custom mod. ebay has one offered at the moment, with some good photographs. I am not affiliated with the seller. I just like the pictures! h

After 45 year, I can still her that sound again. No. This is not a translation of Bizet’s Les pêcheurs de perles. That distinctive crunch was an immediate indictment to all the someone has abused the

Let me know if you have questions about the histogram program. Although it has been a mere 40years, I might be able to remember how and why I did certain things.

Kurt Rosenfeld has posted the entire line printer listing (454 pages) of the 1982 source code version 1.02 for the 7854. It's an early release but it reveals some interesting things.

Ryan, Good citizen! Does your wife know where you are going to put all of that?

Good advice for scavenging parts for a TM500 plugin. Take care with the 7k bottom extrusion. It has a tab to land the latch spring. 7k mainframe rails have a slot to accommodate the latching mechanism

Dennis, The Tek nomenclature guidelines did not restrict us from using three letters. Using two letters for the earlier products was a convenience and a preference that became habit rather than policy

Mike, Thank you for your good citizenship! I miss Cliff as well. He was a strong character, very bright, very practical and a good adviser. As for Dennis' comment about Tek service manuals ditching sc

I cannot say about the 5S14N, but only the 5400 group (5440, 5441 and 5444) of 5k scopes are equipped for CRT display of readout. If you don't have one of those mainframes, your project will be a bit

There were other tricks using 7k plugins such as the 7D11 or the TM500 equivalent digital delay unit. I wasn't a word recognizer but you could delay by counting microprocessor/logic events such as clo

I have an alternate part number for 151-0367-00. The TI part number is SKA6516. The Freescale number is SPS8811. I have a bunch of the Tek number 151-0367-00. They have all been pulled from one of the

Real stunners!!!

Ahhhh. The 7A12. I remember an unofficial accessory that was distributed partly for fun but it proved very useful. It was a pencil with erasers at both ends. After using the 7A12 for 10minutes, the jo

It is a very prestigious person who has Tektronix printed on common coax cables! You are the envy of all.

Dennis, That part number(012-0057-01) is active at the Tek web site but I cannot find details about it. The URL link is below. It appears to be an ordinary, high-priced accessory. A precision cable is

"Strange though, it is exactly the same size as a DS1230." Maybe that's why it was in the salvage pile! On a more serious note, take Maxim information about Dallas with a little caution. For that matt

I found this comment on the Maxim web site at https://maximsupport.microsoftcrmportals.com/en-us/knowledgebase/article/000099786 "The drop in replacement for the DS1235ABW-120 will be the DS1230AB-120

Keyboard error...allow me to continue The only thing that is peculiar is that the mode control buttons (LEFT, ADD, CHOP....) require initialization after each power cycle. There is no memory for momen

David, This board allows you to operate the 7854 as a 7804N. Analog scope functions only and without the readout, hence the N nomenclature. It was created early in the project to allow the analog scop
