Greetings all; Up untill recently my most involved task with video/pinball games have been Cap Kits and replacing Data East power driver board connectors. I have always deffered board repairs to others more qualified. That is till now. I recently purchased a Fluke 9010A with 6502 and Z80 pods from a fellow collector who needed cash and who like me is completely self taught. He convinced me that I could repair boards myself given a little hard work and patience. Now this may have just been part of his sales pitch, but I believed him & bought it. I met Kev a couple years ago & have stayed in touch. He gave me this list to subscribe to. Either in hopes I would come here instead of sending him 100's of emails full of newbish questions, or to generate conversation here. :) I have no background in electronics and everything I do know, I have picked up from working on my own collection of Arcade games & Pinballs the past couple of years. I am probably the last guy who should own a Fluke & should really pass it on to someone who will get better use of it. But before I do that, I would like to see if I can make some small use of it. To compound matters, I picked up a second Fluke 9010A base unit off of ebay. And herein lies my first question. The Ebay one has a digit going out, it flickers, gets real dim, then comes back. The plus side is that it has a RS232 port on it, my original one does not. Can I easily swap the RS232 to my original unit? I havent taken the cover off to see if its just a card or if its hardwired in. Second question concerns Oscilliscopes. First of I know I need one, How do I know? I have been told I do :). I do know I can display the output of Vector games on one that has XY inputs on it. What other uses for it, I am very vague on, but am willing to learn. The problem I am running into is knowing which units have XY inputs and which ones dont. I have been mainly looking at Ebay auctions & while they list alot of features, only one scope have I found so far has actually listed XY inputs ( a TEK 465M). Is there some other name this feature goes by that I am unaware of? Kev has been very patient & helpful, but I dont want to wear out my welcome in his inbox :) So I bring my questions here & hope my lack of knowledge is not to embarrassing apparent. I have picked up a few books & my Fluke came with a 4 cd set instruction set that I have just begun. ANY help would be greatly appreciated.
