I promise not to quote, repeat, rephrase, paraphrase or otherwise imply
anything that Hoare and/or Dijkstra said!!
One of my best friends in High School and during my undergraduate years
(shortly after the invention of electricity) was positively an Algol 68
_fanatic_.? I don't think I ever saw him without that green and white
ACM magazine issue with a focus on Algol 68 which he would whip out at a
moment's notice.? Sometimes it seemed that he thought that a sneeze
could best be expressed in Algol 68.
And he was one of the most brilliant programmers I knew at the time, so
nobody dreamed of considering that he might not be perfectly correct.?
We kept waiting for a DEC implementation of Algol 68.? Even a subset.?
Sigh...

An extract from a document that I like:

As for OSI, the UK Academic 'community' resisted TCP/IP between campuses in the
UK, even keeping us using the dreadful coloured books protocols over X.25, because
"OSI was the way!"

If you will look at the saga of the Algol-68 effort, you will see some uncanny
parallels.
In other words, what we learn from History is that we don't learn from History...

Tops-10 and TOPS-20. I left DEC in about 1983 when they cancelled the Jupiter. My
recollection around then was OSI was supported by the ITU, all of PTTs around the world
and most, if not all, global telecom companies. TCP/IP was seen as a mostly US-originated
short term hack by most of them. Brilliant foresight. Most of us thought this OSI stuff
was BS, but we had to play along. We were all very familiar with TCP/IP and were big fans
and used it daily. I have a map/printout of the ?ARPAnet? in 1978 and it was about 70
nodes, with about 50 nodes being DEC machines.

vendors (including DEC) up until about 1984 thought that OSI was the future. Some on the
DECnet review group (DRG) saw the future as DECnet morphing into the OSI stack. They had
some great people on the DRG, and they correctly pointed out the shortcomings with TCP/IP
(limited addressing (pre-IP 6, vulnerabliliies, poor routing, etc), but history shows they
made the wrong choice and those vulnerabilities were mostly fixed over time. In those
early days most other vendors had horrible proprietary networking solutions and DECnet was
by fair the best.

OSI. I think we sold one copy of the OSI product to GM for their ?factory of the future?
project (OSI/MAP I think it was called). So much for OSI and top down planning! Perhaps
the only thing useful that came out of many years of OSI work was the framework and
terminology.
