  1. Decathlon....my forearms and getting a work out
  2. Most the stuff I let go of I have been able to hunt down....except my first computer, a TRS-80 Model 1 with some cassette games which I can't remember
  3. Success! So I did try the power supply above but when I tested it with a meter it was also running at 7v (cheap chinese product go figure). Dug up another power supply which test at 5V. Thanks so much for all the help...I learned a lot. First thing I did? 10 Print "hello" 20 goto 10 run
  4. This should work right? Good news, the ebay seller refunded my monday....well it's good news if my 800xl isnt toast. I have hopes since the last time I turned it on it was not a black screen.
  5. Will try this...thanks Is there anything in the plastic box that says "To Computer" ?
  6. Yes definitely not trying it again....and lesson learned! The good thing is now I know how to use a multimeter
  7. A friend with a multi meter and familiar with electrical. Said that usually it will read high when testing but once in use it will drop down to 5v once it starts to regulate. I had a second person tell me the same thing. So when I hold down option or put in a cart it does seem the screen changes underneath all that noise. If the dram was fried wouldn't it just be constant? This is why my initial guess was video. Just trying to figure out my next steps...replace the power supply or look for DRAM if that is an option..or ?
  8. Meter is reading about 7v. I was told that is fairly normal. Does this rule out the PS?
  9. This would explain it....I'll test it with a meter. Which Power supply should i be looking for?
  10. I'm not an expert but the solder from the yellow wire seems to be bleeding and bridging to the resistor next to it. Could this cause any issues? Side note: I recently picked up a broken 2600. The fixed was swapping out the TIA chip. It does work but I also see color fringing/bleeding. This is without any type of composite mod.
  11. I found my original 800xl from when I was a kid in the garage. Did not have a power supply so I picked up a 61982 off ebay. When I turn it on I see scrambled video and hear a buzz. This happens when I use the RF out and when using composite out via the monitor port. I recently had a similar issue with a 2600 and swapping out the TIA worked. Could this be as easy as replacing the GTIA or does the buzzing indicate another issue?
