That was my first question as well! I haven’t found any info on the PDP-11 version yet.

While looking for PDP-11 info, I happened to read up on the interesting history of The Mark Williams Company. Apparently they were originally a soft drink company, which Robert Swartz moved into software in the 80’s. And, Robert Swartz is the father of Aaron Swartz!

Their soft drink, Dr. Enuf, is apparently still sold and is in the Cracker Barrel gift shops. I propose it to become the official soft drink of classic computing.
