Cable question

[chrischarla@hotmail.com (chris)]

Hi everyone, I hope someone can help with this monitor cable question.

I have a IIgs I've never hooked up, and a //c I use all the time. I
also have the RGB monitor that came with the IIgs, but no cable to
attach either the //c or the IIgs to it. Does anyone have the specs
for the cable? Is it something I could buy at Radio Shack, or will I
need to brew my own? Finally, would the same cable work for the //c
and the IIgs?

Thanks!
