- Here i repair an Atari 130xe found on ebay at a cheap price! Broken power switch , missing key and probably bad ram! :-)
It's odd that this is the third 130xe that I see with all MT rams but the first one; maybe Atari knew that MT wasn't very reliable? Let me know in the comments about it.
As soon as the hooded eyeball dude appeared in the lower left corner I subscribed
🤣 Thank you 🙂
Nice acquisition! I see MT RAM continues to earn its reputation. Thanks for sharing your experience!
Thanks to you. Yep, MT rams are always a guarantee (that will broke, sooner than later ! )
@@mondo8bit You're welcome! I really like that you were able to fix the switch without replacing it. One question though: @7:31 you entered a bunch of '3's without there being a 3 key on your keyboard... how is that? FRAU BLUCHER!
@@3vi1J 🤣 There's no 3 key, but still there's a piece of the plunger and it works.
Just bought an 130xe motherboard for cheap. It had no power. The power switch was an aftermarket and it was problematic but even after changing it I still could find any 5v around the board. The electrolytic cap (470uf) near the switch was shorted. Got power after changing that but no image. Removed and tested Antic and GTIA and they worked on other machines. It turbed out the 4050 was dead. Finally the monitor picked up a video signal but still it didn't boot. Next stop the cpu....it was dead. Finally it worked and the RAM (non MT) was in good shape! Its the second machine I've encountered with so many issues. Previously only one XEGS had its ram, cpu, and rom gone bad. What those machines had in common is someone had meshed up with the power input. In the case of the xegs the emi coil was roasted!
Anyway its always good to find mt ram inside a machine when it doesn't work. It narrows down the causes of failure! I was happy and disapointed to find a reliable ram brand inside that board. I knew I had an extensive repair of multiple failures in front of me.
Cool, and congratulations for your work on these XEs, you had to do a great work! 🙂 In this one was indeed easier, when you see MT 😀. Sooner or later, when I will have time, there will be 2nd half of the video...!
@@mondo8bit Usually Atari 8bit machines don't fail that bad. Its always a "human hand" meshing with something that creates a mayhem.
Great video and clean work. I also use a hand pump to desolder ICs with 100% success. The key is "patience"! Can't wait for the second part.
Excellent video and repair. Looking forward to your next video! Thanks for sharing
Thank you Rudy!!!
Grande professionista! Complimenti per abilità precisione nel riparare e ottima pronuncia!!! 😊
Grazie mille 🙂
bellissimo video! ottima riparazione!
Ciao MD, grazie mille 🙂
Nice reparir. Good job.
I have a questions because i found me Atari 130xe but when i try to use it, the memory test show me blocks with error.
How i can determinate what is failing? Is better change all the ram?
Thanks for your help
Thank you! About your 130XE: the memory test actually shows only the first 64K memory bank (in the newer 130XEs, there's a new rom, the C300717, that shows also the extended ram, in form of four bigger bars, but I still haven't see one from real). If the ram are MT branded, yes, I would change them all. If not, you could try to change the first 8 chips, put sockets, then check for which one is gone. Let me know... 🙂
Hi, there is a program to enter to test memory mode directly? The function keys are not working
Hello ! AFAIK, you need the function key to enter the memory test 😩. The XE goes automatically in memory test only if during the startup “see” there’s bad ram. You would need a test cart, or maybe a boot disk. Had you tried to remove the keyboard and clean the contact? I solved the “function keys not working” problem cleaning the connector then using a pencil on the Mylar connector traces to make them more conductive.
