[Coco] What do you use for pull-up and pull-down TTL resistor values? (LS series) (coco related project but possibly OT)

[didier derny]

I'm using these products: 
https://www.picotech.com/oscilloscope/2000/picoscope-2000-overview

they work really fine, the input are protected in case of overvoltage

the software has all the options (no hidden fee, with options sold with 
serial or certificats)

the sampling is quite high  (200ms for  25Mhz [2205 the picoscope I had 
in the past the price serioursly dropped])

1Gs/s for 100Mhz  (pricey but works like a charm)

>> ha! good advice Gene!! No doubt you are right.  In fact I could probably use one right now with a practice circuit that has a glitch.  I've built it twice, both times exact same glitch. I am going to work on it some more and will post about it if I can't figure it out.
