  1. Obviously, I mades something worse by rocking the chips the first time around (I didn't remove any, just pulled them up slightly and pushed them back down). Several did seem to go down farther than I pulled them up so I thought I was accomplishing something. So far my accomplishment has been to "brick" the thing completely. Oops. There wasn't much dust to be seen in the 600XL (there is more dust in my one year old Mac Pro), but a cleaning may be in order. I will open it again and start (carefully) poking around, to see if any chips are seated incorrectly and take a look at the schematics and see if I can make some sense of them.


  2. Already had it apart twice in the past hour! Probably should have waited longer for some advice. Anyway, I did have it on for an hour or two last night trying to figure out what was going on, so it should have had some time to warm up then. When I took it apart I just opened it like a book and did not disconnect the keyboard connector. I made sure it was not squashed badly when putting things back together. Of course now it is now a completely inert entity, so that is a problem...


  3. Okay, I opened the XL, removed the heat shield and pulled (slightly) or rocked each chip. Most moved a slight amount, or sounded like they were moving. The wires from the 64K upgrade looked okay. Put it back together, turned it on, and now...

    Nothing!

    No red power light, no blank screen (just continued snow), zip. Could something have been messed up by just rocking the chips? No red light seems like a power supply issue (but the read light was on prior to my foray into the computer). What to look at now? Thanks!


  4. I have a 600XL that I bought at a garage sale back in the late 80's ($6, still in the box!). I had someone upgrade it to 64K and used it for several years. In the mid 90's I boxed it up and it has been in storage since then.

     

    It worked fine when I put it in storage. Yesterday I pull it out and it does not work. When turned on the "power" LED lights up, but that's about it. The TV goes from snow (when the XL is off) to a blank screen (black, reddish tinge after a while) when the XL is turned on. Tried both channel 2 and 3 and tried running it through a VCR's tuner (set to 2 and 3) and the result is the same. Attached a 1050 drive that appears to still work (lights up and goes through the "spin up" when inserting a disk) and tried to to boot a disk. The 600XL does not appear to communicate with the drive as the drive does not do anything when the XL is turned on.

     

    Do these old 8-bit Ataris die of old age if they are not used? Any ideas what could be the problem?

     

    Thanks!
