Vintage Atari Mega ST 1 MegaST Computer - Upgraded, 4MB RAM, New PSU, TOS 1.04.


I’m selling off my vintage Atari items. Being hard to find, I had to import this Mega ST 1 from Europe a few years ago, and in the shipping process, it received some rear case damage and lost the battery door. This is purely cosmetic - none of this impacts functionality. Please examine photos carefully.


After acquiring this, I had a 4MB RAM upgrade board installed (maximum), RaInbow TOS 1.04 installed (latest), and a new 110V/220V power supply installed. I used it to play some vintage games but otherwise it’s been in storage since moving on to vintage Macs.


No accessories or cables will be included - only the computer itself is included in this listing. It originally had an accompanying Megafile 30 hard disk, but I’m listing that separately.


As with all my vintage computing items, this is being sold as-is without warranty and no returns offered. My commitment is to deliver this equipment to you as pictured but I cannot guarantee functionality — it’s 30 years old! That said, it did seem to function as it should in my testing and I’ve provided screenshots of various diagnostics performed. The monitor is not included - screens shown for your information only.


Shipping costs what it does because it will include full insurance for our mutual protection and it will be well packed - typically double-boxed.


Read my response and buy with confidence. I’m not perfect but I always try my best and I am fair.


Thank you.
