Thanks for the heads-up, folks. This IIc is going to be both a challenge and fun. Short story time:

When I was mowing lawns in my junior year of HS, one of my customers had a //c. I gushed over it, and so he made me a deal: If I cut his lawns enough times, I'd get the //c instead of the usual payment. After gladly accepting, really looked forward to getting that machine. Alas, I'd signed up for the Army Reserve and had to ship off to Basic Training before I could close the deal, and the fellow just paid me what he owed.

So, here I am - retired from the Army with time and some money (though less than I'd hoped) on my hands - so getting this machine will be a long wish fulfilled.
