Well, there's your answer. They are all in the V6 library. Here's the source for setexit/reset: https://minnie.tuhs.org/cgi-bin/utree.pl?file=V6/usr/source/s5/reset.s You do realize that if you got it compiled under V7 and ran it, it would trash the disk, right? (The V6 and V7 filesystems are different; very similar, but block nubers are 16 bits on V6, ans 32 bits on V7.) > Is there a makefile? No. No 'make' in V6. Which is why you find those 'run' shell files: https://minnie.tuhs.org/cgi-bin/utree.pl?file=V6/usr/source/s4/run everywhere. > From: John Cowan > It was an update/rewrite of the MIT version. Which one? There were two: "MIT's AI Lab", by CSTACY, Alan Wecsler, and me; which Rob Austein re-wrote into "Alice's PDP-10". I thought the original was centered around ITS, but my memory was poor (hey, it has been ~40 years :-), it seems to sort of be about LISP Machines. Rob's version was about TWENEX (yech). The original was written in 926, MOON's office; I can't believe he put up with me hanging out there! >> Although I like the old story about the person at their oral exam and >> the Coke bottle in the window. > Details? So they're giving someone an oral exam. They can't make up their minds, or something, and they ask the person to step out for a second. When the person comes back in, they point to a Coke bottle sitting on a window-sill in the sunlight, and ask them to examine it. The person notices that it's warm on one side - the side facing the window. 'Why that side?', they ask. So the person goes into a long explanation about how the curved glass must have focused the light, yadda-yadda. WRONG! They turned it around while the person was out of the room. I think that the person fails their oral. I have no idea if it's a true story. Steve Ward told another oral story which I'm pretty sure _is_ true, though. They ask the candidate to design a state machine (or digital logic, I forget which) which can tell if a number is divisible by three (I think I have the details correct, but I'm not absolutely certain). So they describe one - and then point out that you can feed the number in from either end (most or least significant end first) - and proves that it will work either way! The committee was blown away. Noel
