Yes, the point is to alleviate the tedium of the long winter nights by souping up a System 6 machine. It turns out that I have no IIci, but I do have a IIsi in nice shape.

Having said that, I may just find myself a IIci to play with, since, as has been said, it is so much easier to deal with — but that IIsi adapter would be a welcome addition to the pile should anyone have one to offer for sale.
