  1. The retired, 75 yr old guy ran it out of his radio repair shop. I asked him what the most common repairs were back in the day, he said controller ports and regulators. Back in his hayday, He made a device to process and display morse code over a phone line onto his Atari screen. I told him about the 1Mb ram, drive emulators and Fujinet, he was surprised to hear about it. I gave him $100, the salt diag cart is worth something. Also gave me 4 boxes of sealed 5 1/4 floppies.
  2. I finally got a decent Atari haul, yay! I responded to an ad for 400/800 atari service manuals. I came home with many free original binders of schematics and manuals of all their stuff alongside the remnants of an authorized Atari service center parts inventory. I guess im in business now 😄 No Pokey chips but many ram cpu and couple video chips. Anything else interesting?
  3. There is a third party library I develop some scraper apps with, HtmlAgility, and they replaced some of their docs with a box to ask GPT to get answers using their code.Ding! It gave me the correct answer, or line of code. I was a little worried about trying to explain my question since I was a little rusty. Good potential.
  4. This very fortunate and honest guy who landed on a goddamn Atariage gold mine auto-declined my offer.
  5. Maybe you played this as youth in the late 80's after playing Atari. The stuffed potato played a tune after being triggered by a squeeze, you passed it around. When tune randomly stops you pick a card. I want to pass along my hot potato to a nephew but it needs service. The coin battery was corroded. It had no markings on it. I tested it with a LR44 1.5v alkaline, it worked but the output was about 1/3 of what is should be. I tried a new 27mm coin piezo with same results. Hail mary with 3v battery thinking maybe it was a custom battery, but it played really slow. Its fascinating this little epoxy glob can store a melody, a timer of sorts and the means to amplify playback. Did it loose some of its amplification magic over the decades, or battery issue? Its just not loud enough. A disk cap, pressure pad-type switch, and the tiny IC that is it.
  6. If above doesnt fruit results check output opamp for energy. Check base of Q100 for energy both during playback. Check cable for continuity. I dont see any caps in signal path. Taken from http://www.atarimania.com/documents/Atari_410_Program_Cassette_Recorder_Field_Service_Manual.pdf
  7. Amazing score. I would’ve bought $100 worth of fireworks right away and light them all off at the same time in excitement. Sellers email or phone must have blown up! “Stanley dear we have 120 missed calls what should we do?” Im keepin my eye on those retired boomers wanting to lighten their load. I’m asking every old person I see from now on.
  8. Thank you for the reminder. I do not feel lower noise opamp would make any difference. My unit will save and load basic programs from tape but not prerecorded games or games recorded onto fresh tape. Tried playing with tape leader. Can here the sounds but end up with load error. Had idea of using cassette adapter feeding signal from .wav on laptop to eliminate 410 as fault. Does the Atari 400 process BASIC signal differently than cassette games?
  9. I actually replaced all resistors on a 410 with 1% metal film hoping it was noise in signal causing loading errors but it didn’t fix the issue. Dont recall if there is a opamp in the signal path, that was my next suspect.
  10. Nope he wants USD. I asked him in one email if he meant $200, he replied, and I quote "no. it's worth that much and it's an original. barely ever used. nothing is wrong with it. "
  11. I changed my mind. Didnt send it yet if anyone has anything else to add.
  12. Well he accepted my offer of $1700, guess he is serious about this rare Atari 2600. Should I meet up with him and whack him with a stick?
