Chaos Protocol Posted January 6, 2003 Share Posted January 6, 2003 I have come across a mystery power supply in my many boxes of 8-bit. It's the same exact size as the standard 1050 drive power supply, but it has a different shaped top with the Atari logo (no Warner Communications Company text) and the wires come out of both sides like the computer power units, not both cables out of one side like other disk drives. Also, the power rating is different 1050 source: Mystery Source Part #:C017945 Part #:CA014748 Input: Output Input: Output: 120v 9V AC 120 VAC 9 VAC 60Hz 31 VA 60 Hz 15.9 VA 50W 20W the power jacks are identical (both fit the 1050) Also, the Mystery Source has "Atari Inc. Sunnyvale, CA" on the bottom Quote Link to comment Share on other sites More sharing options...
Callipygous Posted January 6, 2003 Share Posted January 6, 2003 Its listed in the 8-bit FAQ. http://www.faqs.org/faqs/atari-8-bit/faq/s...section-34.html Apparently there are four different 9V PS for the 400/800/1050 etc. Guessing the higher amp models are more reliable.

jjessop Posted January 7, 2003 Share Posted January 7, 2003 The higher amp supplies were for the disk drives. When an 810 would first start up (especially the latter ones with data seperators and new analog boards) they would exceed the supply output with the high motor spindle and stepper in rush currents.
