content: Hey guys,I am getting started with messing with older microprocessors,and testing is getting harder and harder without an oscilloscope, so i'm looking for an older analog one for cheap. Asked around on a few forums and was directed to the EEVblog. Would be willing to buy or trade some new(ish) tech in exchange. I'm looking for one that would be good for a beginner to learn on, as i have very little experience when it comes to timings, clocks, and oscilloscopes in general.Thanks for your time,RM

content: How cheap? Most cheap analog scopes that actually work generally go for around 100 bucks. Sure you can find some for 50 bucks, but then there is that shipping costs. Old analog scopes weigh a ton. One thing I worry about buying an old analog scope is about the huge problems. Switches and pots are probably going to be cleaned and electrolytic caps could fail at any time. There is nothing worse than spending more time repairing your equipment than doing what you want to do instead. Sure you wouldn't be interested in one of those new cheap digital scope for about 300 bucks instead?

content: I understand that repair would be major thing to consider with analog scopes, but ins't bringing something into working order half the fun of electronics? Joking aside, I want analog because of that fact. They are generally more repairable than newer digital ones. Not saying i wont consider digital, just that I'd prefer analog.Edit: A few non-capitalized "I"s bugged me.

content: Yes you do make a few good points. Although I suppose many of them, parts are going to be hard to find for those older scopes. And older scopes are generally huge. I still have a Tektronix Type 545B and a Tektronix Type 575 Curve Tracer from the 60's. Last time I fired them up was about 10 years ago and they were still working just fine. I don't know if I would be interested in using them or repairing them anymore though.

content: Depends on if it works. I saw this a few days ago, seemed like an ok deal if it worked. Keep us posted, I want to know if it works.
