Not my auctions, but you gotta check this out if you always wanted an oscilloscope: http://business.search.ebay.com/_Business-Industrial_W0QQsacatZ12576QQsassZgreentekusa I have one of these since 1996 and still works fine. It's a great little scope, especially when connected to a laptop/pc. The price REALLY cheap and definitly worth it. You can power it mostly directly from the PCB you're working on (12V). The frequency range of it is more than adequate for the classic games (up tot the 90's I'd say). Don't expect to be able to read Ghz's with it... |

Something like this would be perfect for testing all of my dead system 1 pinball boards! I've put it off because I didn't have an oscilloscope. I think I might be in for one of these. My basic requirements are Mhz frequency readings for an on-board crystal, and simple logic probing that is too quick for a DMM to pick up accurately. |

I'd be all over that if I didn't have two scopes already. |

You can do frequency reading with the PC software (you gotta move cursors for that, but that's normal for a digital scope.... |

Make sure you're testing them in a completely solid machine before you write them off as dead. --- End quote --- All connectors replaced in machine. Still, boards are tested on test bench with bench power supply. Unfortunately in system 1, pretty much anything on the board can cause it to not start up. And you just have to hope that all the "road block" replaceable components were able to sacrifice themselves to save the spider chips. ;D |
