Re: 2445A calibration
<snip>
I probably would have liked the ones for the 8085 and the 6502, just
because. Every once and while, I need to look at some of those old
ones. Right now it's the 6802 that I need to look at.

Re: 468 horizontal jitter
Thanks Jeff.
There is jitter on the A gate out with no input just a free running trace. I had to put my 465 in 10x to see it but it does match the jitter on the 468. So... This looks like its going

Re: 468 horizontal jitter
In case you haven't, it is important to check if it is a centering problem or a triggering problem. Even in auto or free run it is still triggered, so if it is the problem could be all the way back

Re: 2445A calibration
To be a bit pedantic, to me, square wave doesn't talk about the
levels, so where's 0 and where's Vmax...?
bet there's lots of opinions on that one.

Re: 2445A calibration
There are some situations where the LA can be of use, but mostly for
tracking specific events under specific conditions, IMHO.

Re: vintageTEK museum releases Replaceable Parts Registry (RPR)
Thanks so much for another great RPR scan, the 311 set is very handy to have!
I can hardly wait for that 366 scan, it will answer a lot of questions.

Chuck,
I've been using all sorts of LAs since the beginning of 90s in the reverse engineering for the systems with scarse or no technical documentation. Simply at the start I had my own home built
