I was taking a VLSI design course in 1981, and the professor teaching it proudly showed off some 432 chips (embedded in plastic) that he'd been given. He waxed lyrically about them, how the big boys were doing silicon in Silly Valley. (We, with our colored pencils, were learning how to do NAND gates and full adders in NMOS, on graph paper).
Later, I read Organick's book on the 432. It was kind of a mess, no idea how they expected the thing to perform.
This was also back when ADA was the up-and-coming language, which the 432 was going to run really well (if you believed the marketing). ADA was pretty intimidating, as it was complicated for the time and generics seemed to scare everyone. (Little did we know that C++ was going to be a thing in a decade or so, and it made ADA seem simple in comparison).
- chasil 4y agoADA evolved into the procedural scripting syntax of many SQL databases. "SQL/PSM is derived, seemingly directly, from Oracle's PL/SQL. Oracle developed PL/SQL and released it in 1991, basing the language on the US Department of Defense's Ada programming language... IBM's SQL PL (used in DB2) and Mimer SQL's PSM were the first two products officially implementing SQL/PSM. It is commonly thought that these two languages, and perhaps also MySQL/MariaDB's procedural language, are closest to the SQL/PSM standard. However, a PostgreSQL addon implements SQL/PSM (alongside its other procedural languages like the PL/SQL-derived plpgsql), although it is not part of the core product." https://en.wikipedia.org/wiki/SQL/PSM https://en.wikipedia.org/wiki/SQL/PSM
