Spacewar on an emulated PDP-1

This is great! I love seeing in-depth digital preservation. While I'm way too young to remember the original Spacewar, the DOS decedent of the same name will forever be a fond childhood memory.

On a completely unrelated note, somewhere I have some amazing 5'x8' (yes feet) ASCII-art mosaics or the Mona Lisa and the moon on green-bar from the early 70s. I should probably take steps to preserve them. Or at least share them.
