Crc_Error

Thank you very much for info. I would love to build one over time that is. I think I saw this posting for the 800XL https://www.ebay.com/sch/i.html?_from=R40&_trksid=p4432023.m570.l1313&_nkw=800xl+remake&_sacat=0 but don't know much about them if they are a final working product or where to start getting parts. But yours looks amazing. Would make a great winter electronics project your 130XE remake that is. Anyways thanks for info.

scorpio_ny where can one source the complete parts list also does that fit into a 130XE case? Is that the final version of the motherboard without any errors? Sorry if I'm asking stupid questions....

Just found my old 600XL bill of sale. Thought to myself wouldn't it be amazing if it's still kicking around. Bought it 1984 in British Columbia for $203 CDN. Sold it off along with all my Atari gear in the 90's. Obviously I regretted it then and bigtime regret it today. But from what I have seen hardcore Atarians have sold their Atari-8bits more than once. Anyways I am very curious if 600XL #83 43118 is still kicking around. Cheers to all!

I'll PM you

Perfect thanks I will order one from TBA or Retro Lemon. Thanks

Where can one buy the latest Fujinet, the 1.7 version I think it is? I have looked online at most internet stores and only see the 1.3. Thanks for any onfo.

Would love a board when they are available

Interesting I do need a new mylar for sure but when I tried to re-attach the keyboard after cleaning the mylar the computer booted up with the old problem. I immediately unhooked keyboard and it works great still in booting up. So I thing the faulty keyboard actually fried the OS chip. Thats my conclusion at least,

Yay I got it working after all these days. It was the faulty OS Chip. I swapped it out of my 130XE parts motherboard which in the future I'll work on too. It's an amazing feeling getting it to work. I also found out the problem with the keyboard (check photos). @bfollowell I owe you a beer! Can I use the repair kit which people use to repair their rear window defrost if their traces in the window burn out or break? Cheaper than buying a mylar for 70 bucks with shipping into Canada. I learned the hard way when I received the 2 UAV's from the TBA, had to bay another 50 CDN for brokerage fees. UPS sucks in that regards! Anyways this 600XL is back to life, well almost. Thanks to all of you who helped me. You rock! Long live A8's! 20220929_203001.mp4

Been working on it lots last few hours. Things that I figured out is that the POKEY & MMU work perfectly. Luckily I had a 130XE motherboard that I was using as a parts board so I swapped them, the POKEY and MMU out. Still have the same boot up issue but memory, sound tests pass perfectly. The keyboard test fails again with the different POKEY which leads me to believe its an actual keyboard issue. Next on the agenda is to do a complete re-cap of the board. Power supply is perfect too. I will get this 600XL working one way or another. All I can say is the UAV is an amazing little after-market mod that does wonders to the vintage A8 computers. I might look into replacing all the memory related chips too just to be on the safe side. Here locally they can be found relatively cheap. Thank you for all your help guys without your ideas, pointers and clues it helped me out quite a bit.

This is the keyboard. I now have another problem. Memory is fine, UAV is fine but now on bootup it goes immediately into the Memory Test screen which it passes with 48K and ROM passes too, Really fustrating now. Even with keyboard not plugged in it goes directly to memory test. I might have to use an old 130XE which I have and has issues too as a parts computer and pull the Pokey and 2 4051 IC's. I wanted to buy the Pokey Max but can't find one online for sale. The stock Pokey chips are insanely expensive.

This is where I grounded on the DIN jack as per instructions of UAV. Also I cut the bottom pcb fat trace between pins 2 and 5. Also where I picked off the Chroma signal according to UAV installation manual.

Further to my testing I really wanted to make sure my keyboard worked and found out the " 0, 9 clear and insert " keys don't work. So I suspect I might of cornered the problem with the weird boot up sound. I might have a faulty POKEY chip. Am I wrong with my assumption? Will work on it further tomorrow as I would like to tackle this with a fresh mind. Thank you to all for helping me. Cheers and good night!

One bar on the ROM goes dark when I pull U18. I put it back in.

I might do that with the info. from here https://console5.com/wiki/Atari_600XL ? I take it theres a specific Poke statement that will tell me which rev on basic I have?
