I remember those, had one with an old Mac SE 2. A quick google search turned up this: http://www.parts-express.com/pe/showdetl.cfm?partnumber=244-4172&utm_source=google&utm_medium=cpc&utm_campaign=pla It looks like a simple switched outlet strip, you could probably find them at places that sell stuff for servers and audio hardware.
I have a similar one behind my bench that I use to turn on various lights and small shop tools, very handy.
