Somewhat related to the 10 year rule :) fixing systems, aligning drives and
building NOS z-80, etc.
I would like reccomendations for inexpensive-ish oscilloscopes :)
Personally, I'd rather have a second-hand Tektronix than a new no-name
(and the price could well be comparable).
What sort of bandwidth does one need, are there any materials out there for
A reasoanble rule of thunb is that you need a bandwidth of 3 times the
fastest (clock) signal you want to observe. So if yoy're working one a
machine with an 8MHz master clock, then a 25MHz 'scope is OK. If you want
to work on a PDP11/45 (33MHz clock), then you really need a 100MHz 'scope
But you can often get by with a lot less...
