Hi all, not exactly a scope, but a Tektronix. :-) I inherited two of these boxes, apparently working. Both have quick-user-guide inside the flap, but I'm unable to find a decent user manual, less a se

Dear all, I bought the "functional replacement" chips of the Dallas DS1650 and DS1486 to replace the ones in my scope. I have downloaded the the TdsNvramFloppyTools and read the 1486 several times bef
