Dreamed about Intel 808x assembly language last night - that hasn't happened in years.

The Lambda Papers: When LISP got turned into a Microprocessor.

During the AI research boom of the 1970s, the LISP language — from LISt Processor — saw a major surge in use and development, including many dialects being developed. One of these dialects was Scheme-78, developed by [Guy L. Steele] & [Gerald Jay Sussman], who wrote a number of articles that were published by the Massachusetts Institute of Technology [MIT] AI Lab as part of the AI Memos.

This subset, called the Lambda Papers, cover the ideas from both men about lambda calculus, its application with LISP and ultimately the 1980 paper on the design of a LISP-based microprocessor.

⁉️Scheme is notable here because it influenced the development of what would be standardized in 1994 as Common Lisp, which is what can be called ‘modern Lisp’.⁉️

<https://en.wikipedia.org/wiki/Scheme_(programming_language)>

👾The idea of creating dedicated LISP machines was not a new one, driven by the processing requirements of AI systems. The mismatch between the S-expressions of LISP and the typical way that assembly uses the CPUs of the era led to the development of CPUs with dedicated hardware support for LISP.👾

⁉️The physical layout of the SCHEME-78 LISP-based microprocessor by Steele and Sussman.⁉️

The design described by [Steele] and [Sussman] in their 1980 paper, as featured in the Communications of the ACM, features an instruction set architecture [ISA] that matches the LISP language more closely. As described, it is effectively a hardware-based LISP interpreter, implemented in a VLSI chip, called the SCHEME-78.

By moving as much as possible into hardware, obviously performance is much improved. This is somewhat like how today’s AI boom is based around dedicated vector processors that excel at inference, unlike generic CPUs.

👾During the 1980s LISP machines began to integrate more and more hardware features, with the Symbolics and LMI systems featuring heavily. Later these systems also began to be marketed towards non-AI uses like 3D modelling and computer graphics. As however funding for AI research dried up and commodity hardware began to outpace specialized processors, so too did these systems vanish.👾

Rusya'nın işlemci konudaki birikimi çok yüksektir.

Batı bile bunları yazarken şu anda kullandığım bilgisayarda hâlâ takılı olan G4400 İntel Pentium işlemcilere de adını veren Rus mühendis "Vladimir Pentkovski" sâyesinde bu ileri işlemci teknolojisine geçebilmişti!

Onun adını onurlandırmak için işlemciye "Pentium" dendiği yazıyor!

The KIM-1, short for Keyboard Input Monitor, is a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price (thanks to the inexpensive 6502 microprocessor) and easy-access expandability. - Wikipedia

Discovered this very early historic home computer from my morning music "On the Other Ocean the debut studio album by American composer David Behrman,.. Considered a pioneering work of computer music, the album pairs electronics controlled by a KIM-1 computer with live players."

Predictably and wonderfully, we can build one ourselves.

I'm a bit ashamed to admit that I once owned a quite extensive list of "unintended" opcodes in then popular microprocessors like the 6502 or the Z80, but somehow lost it after having finished university and moved on to later technologies. 😭

So, at some time between the end of the 80s and now, my virtual cat or imagined dog must have eaten it. 😉

May be you can still find that stuff on the interwebs, hidden somewhere in between all that AI slop. Wikipedia might help you.

To give you a hint from ancient memories: The Z80 could architecturally access its registers in both 8 bit and 16 bit chunks - except for the IX and IY ones. Documented as index registers like the well-known HL one (i.e. concatenated H and L), they were portrayed as non-splittable. But they were as people found out, giving you more independently manipulatable registers for situations where you could take advantage of that capability. The IX/IY prefixes were functional pretty much everywhere. Later implementations of the Z80 architecture may have lost that undocumented capability.

`We have published several retrospectives highlighting Intel’s 4004, and it was indeed pivotal to the development of the PC and the industry that holds many of us in thrall to this day. However, there’s an alternative future where the MP944 wasn’t kept secret for over a quarter-century, and one wonders what the shape of the computer industry would be in that case.`
