Just come across this scope free. Any good?

If you are going to get an Analog scope... watch for a Tektronix 465, 465A, 475, or 475A. They are all basically the same except for bandwidth:

465: 100MHz
465B: 100MHz (with improved performance (in what ways I don't know))
475: 200MHz
475A: 250MHz

These scopes have XY mode as well, which is good for testing the vector output of vector games.

Any of the above should pop up for $50 - $150 depending on included probes, DM44 DVM option, etc.

Always try to get a scope from someone who has used it. Hopefully they'll be honest, and they can at least give you history, any glitches/etc.

The units I mention above can require cleaning of the many contacts that the rotary selectors control. I have 2 myself, and one does require cleaning, as it can be a little glitching when selecting the volts/div on channel 1.

There are also many great resources on fixing these scopes should you find a problem, as they were produced for many years with many units sold.
 
Well, like I said, I had no plans on getting one, but it was free. Just wondered if it was worth getting new leads for use in this hobby.

leads can be expensive (up to $50-100) for a pair, but again, that's depending on the brand and how high the bandwidth can go up to (50Mhz ~ 200Mhz ~ higher?)

I just want to reiterate that your oscope max of 1 or 2 or 2.5Mhz can't do much for arcade game testing.. But someone else can chime in if I am not entirely correct.
 
I'll second cwilbar in his remarks. I have a 60mhz scope at home and it's only really good for the older Atari boards that run 16mhz and under. (Scope Bandwidth = 4x max freq is up on the limit where the signal is unreadable) Mostly useless on the 32Mhz System 2 boards I need to fix up.

I just picked up a 1660cs logic analyzer which has a 2 channel 250mhz scope in it. So now I can test chips/logic and have a decent digital storage scope in one. Problem is it doesn't have an XY mode. Boo...
 
With that low bandwidth scope, if you can come up with a set of used leads dirt cheap... you could use it to troubleshoot power circuits and audio circuits. But you won't be able to really look at the fast transitions happening in the digital circuits.
