Yeah found it on Craigslist.
Long story short, I live in Endicott, NY. Birthplace of IBM. My great grandfather helped construct Building 32 "The Clock Tower" and the IBM Schoolhouse building. Every generation has worked at some point in time inside of an IBM building here in Endicott. There's a ton of history in the family. Hell, I practically grew up at the IBM Country Club. Stuffing my face with hot dogs and cheeseburgers in the lounge overlooking the 1st tee of the golf course, playing basketball in the gym, swimming in the pools, burying my brother in sand outside on the playground and attending huge IBM employee Christmas parties in the ball room where every child in attendance received a gift from the company.
My grandfather had an original 5150 with the Model F. That's on display in my uncle's computer room / office. I have my fathers PC XT (21mb HDD / 360kb 5-1/4" floppy) with the 1390120 no LED / silver badge and a 5155 Portable PC that rocks the tiny orange monochrome screen. Classics that have been preserved without lots of wear & tear and all of them power up and will boot to DOS 3.3. Nothing like hearing the crack of the power switch in the back corner of the PC get flipped and it start to make that perfect whine while it comes to life.
I even have a couple Unicomp boards I bought a couple years ago. They're decent but the two that I have, the build quality is not consistent.
Question is, really how rare are these SSK's? I knew they existed but I've always been the full 101-key type guy.
