Information on original IBM 5150 PC power supply?

I was wondering about the internals of the original IBM PC power supply, and figured the people here might be able to fill me in. Did it use the TL494? What topology did the PSU use? It was made by Astec, right? Does anyone have a schematic? (Probably too much to hope for.) I've searched the web, but couldn't find much information except it was 63.5W.

Thanks,
Ken
