acdw, I have had a day. I am feeling so drained and so tired of everything. I saw on spacewalk that you had updated and got a little excited (I tend to enjoy your writing). Your post* was quite funny and I loved your commentary and it really just turned my night around and cleared my head to read it. Thank you!!
As an aside: an 80 column card likely refers to a display card that makes 80 character wide rows (80 columns) possible. 40 was common once upon a time.
Definitely do more commentary on old humor if you find any more good stuff! I also wonder if any of those numbers still work, but I no longer have a modem of that sort :-/
