"Huh? What? My 200Mhz, 2Gs/sec Tek TDS LCD scope works just fine thank
you..."
Yea, and I bet you didn't pay $800 for it, either. I perhaps should have
expounded my distrust/distaste for the LCD scopes to more clearly say
"handheld" scopes. I had a TDS scope at IBM (4 actually), and I dearly
loved those things. They weren't *always* a substitute for a 2465B, but in
most cases they were.
And, ironically, they run Windows 95... I did boot Linux on one much to
the consternation of the Tek guy, tho. Couldn't use it as a scope, but it
really paniced him to see the scope tore open, and a spare drive hanging out
of it. Oh yea, I also added a network card (supported under W95), and was
able to FTP files off to the server to backup images and configurations.

Huh? What? My 200Mhz, 2Gs/sec Tek TDS LCD scope works
just fine thank you...
