I miss my Mega ST2. The motherboard on mine looked like the one you picked up for a spare. Where the RAM chips are is an outline of where more chips could go. I soldered in sockets on all of mine and added more RAM and turned mine into a Mega ST4. I never had a color monitor for it. I got the monochrome monitor as I used mine for Desktop Publishing with PageStream.
Thank you. I am glad you appreciate it. And you are right. There are not so many repair videos online of the Atari STs. Let's hope this one will be useful for someone.
Lot of work for such old computer :-) But if you can get the megabit D-ram for low cost, why not upgrade the Atari to 4 MB? I believe it can be done with the piggybank method ;-)

Nice work! I though about combining all of the RAM chips from both boards. But desoldering them is hell, so I did not continue.
@@ezContents yeah, back when I did mine, those ram chips were easy to get.
The diagnostic cartrige would show you which RAM chip failed/MMU - over serial connection. You were lucky!
Yes... That was actually something I wanted to try. Too bad that I got lucky. 🙂
@@ezContents Yeah, based on experience - first thing to test out with any ST is the serial port, right after checking voltages! Cheers!
I enjoyed this very much. Thanks for putting it together. :)
Thank you for the comment. I enjoyed making it.
Really nice video :) Atari repairs on ST line are not so common :) 5/5

Nice fixes there! That's quite a modified unit.
I bought a Atari PC back in 1987, still have it, and the motherboard looks a lot like the one in the video.
I am glad to hear that. Cherish it!

Yes, maybe. I will see what the upgrading options are. Thanks for the tip.
