While clearing out some boxes I found this:




Might help me with my assembler programming.

This came out of my dads computing book collection.
He worked for prime in the 70s and programmed some seriously old systems before that.

I miss talking tech with him.

Nice! Nostalgia and technology go very well together, I've found.

what no COMPARE AND SWAP? hardly a canonical listing of useful instructions :)

There are 7 different compare instructions but no swap.
There's 4 pages of operators, more than I expected.

Anyone like me to do a high res scan of it?

Sure, sounds like a neat thing to have archived someplace!

those are logical/arithmetic, COMPARE AND SWAP is used for multiprocessor synchronization.

We have an oldtimer at work who started out on IBM/360. A great guy and one of the best developers I've met. I should get him a book like this for when he retires

CAS was one of the main ISA improvements of S-370 with respect of S-360, obscure computing jokes are had to decode, so I could be completely wrong.

A bit of background: CAS improves the performance of semaphorres or mutexes used in multiprogramming/concurrency significantly by basically removing the need for non-atomic locks. Almost every modern CPU architecture includes a version of that instruction nowadays.

FYI: IBM ISA's are a trip, in a sense they set the standard for most aspects of computer architecture, so certain things are very familiar. But they have some weird stuff in there that throws you off. But then I am a dork in this regard, so... never mind.

Just for fun, I looked on Amazon and it seems to be readily available used for pretty much the price of shipping

Not really suprising. I saved a load of books that my dad was going to throw out so he obviously found they had outlived usefulness.

I'm sure it has sentimental value of course. The link was primarily intended for Pontus so he could pick up a gift copy for his co-worker; I apologize if it came across otherwise.

I have some System 360 books... The more interesting is one is about the design decisions they made.. its about 2 or 3 inches thick... I love it when university libraries dump stuff into a sports hall and sells it for like $2. Just because no one has borrowed the book for a couple of decades.

No problem. No need for apology.

I'm sure many of us have completely (monetarily) worthless items that have great sentimental value. When it comes to old tech, that is probably always the way.
Even to this day, I'll still put a 5 1/4 floppy drive in my PC, if only to make youngsters at LAN's go "WTF is that?"
Next time I go I'll take one of the SGI's and see if I can make anyone drool over the design.

I mentioned the discussion of the IBM 360 and the lack of CAS to my friend the oldtimer (who cut his teeth on 360), he immediately replied that it was thankfully added, as R-ten-K stated, to the 370 ISA and it enabled a good implementation of optimistic concurrency in the RDBMS which we still develop today
