What is the technique for using these needles then? You heat the joint with an iron and then push the needle over it quickly?

This is true; one technique I use when using the vacuum desoldering gun is to move the tip in a small circle while desoldering/pumping to try to pull all the solder possible out. It seems to do a better job that way. Also, if it is the smallest amount of connection after that, using something...

I agree above about - it is all about the terms. When one person is unloading something to another, the first person is somewhat washing their hands of it, but ultimately, the terms of the arrangement are what matter. The receiver either abides by the terms or they don't. If the receiver...

Did even the later/final 1.44MB drives continue to do this? I've got a USB 1.44MB floppy that normally can write 720K disks and then I can read them in my T1100 plus. But then there are other 720K disks (they seem really early) that if I try to write them in the USB 1.44MB floppy drive, they...

I picked up a DLT external drive enclosure with drive from eBay for I think less than $30. Pulled the DLT drive from it and put a pair of Teac 55GFR's in there for use with the Altair 8800C I built.

Happy Easter!

Higher end are the Saleae LA's, but they are pricey. They stream over USB so no sample buffer limit to worry about. The software requires a modern PC with lots of processing power and their USB3 solutions are the best ones. https://www.saleae.com/ A bit long in the tooth is a LogicPort, you...

I took a PC-6082 apart - most everything was gummed up from dried lubricant. Once I cleaned it up and re-lubricated it, it began working. I was pretty lucky to get it back together.

From the NEC TREK User's Guide: The NSPS Feature The NEC Search and Play System (NSPS) makes loading a tape even easier than just described There are many times where you have five or six programs stored on one side of the tape. To find the program you want easily, the NSPS can be used...

It was a DOD teacher on a military base. The funny thing to me is how much it has stuck with me over the years as that was the 80s.

Yep, I had to recite them perfectly and without one single error or it was a fail. Students could choose amounts from 25 to 200 and would get a specific number of A assignments depending on their choice. I got 8 A's for it!

This is what I can still remember from the 200 digits of PI I memorized in 6th grade - at least I can still recall 55 digits correctly! 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209

I have the same - it will stop working and then you let it sit until it cools down.
