That's awesome. I'll wager it is only the second PDP-7 to boot unix, and the first PDP-7A. And maybe the 6th machine ever. Well done.

Subject: UNIX-7 boots on sn 129

   Hello Folks .. you’ll hear through official channels along with videos
   and pictures (hopefully soon) that we just got PDP-7 UNICS to boot on
   a real PDP-7 (sn 129) using our newly designed “JK09” disk drive.

   The recent posting of source is going to be great .. we’ve been using
   the simh image that has been available for a while.

   BTW, compiling the B Hello World on a real 7 is much more satisfying
   than it is under simh …

   More to come, please watch Living Computers for updates.
   (PS sorry we’re late to the BTL party).
