Some lesser known achievements of Phil (Philip A.) Kaufman

Posted by jpluimers on 2026/02/10

Sometimes Wikipedia entries are way too short, for instance Philip A. Kaufman – Wikipedia, who in 1992 – at the age of around 50 – died way to early, does not do justice to his time at Intel.

His name rang a bell when searching for early Intel 8087 documentation distributed via LISTSERV, so below is a bit more information on Phil.

True, his life after Intel was very important especially on the front of electronic design automation. That in fact sparked the posthumous instantiation of the Phil Kaufman Award which you can read for instance at [Wayback/Archive] The Phil Kaufman Award Dinner Is Later this Month. Who Was Phil Kaufman? – Breakfast Bytes – Cadence Blogs – Cadence Community.

After his floating-point endeavours at Intel and the IEEE, he was also very instrumental at Intel in finding another big market for silicon: network controller chips (and getting the Ethernet standard going: think DIX (Digital/Intel/Xerox) [Wayback/Archive] Ethernet Blue Book (1980) which was named that way earlier than the PostScript Blue Book (1986) and CD Blue Book (1986)).

This period is very well described in the [Wayback/Archive] 1988 Computer History Museum interview of Phil Kaufman by James L. Pelkey (via [Wayback/Archive] Phil Kaufman | History of Computer Communications).

Back to floating point: Phil’s post from 1987 way better describes what early processor technologies at Intel he was involved with than the above links. That period was instrumental in getting IEEE_754-1985 going (it was released way after the 8087!) and still shapes the floating point aspects of almost any CPU from any vendor today so I quote it in full from [Wayback/Archive] Info-IBMPC V6 #59:

Found back some emails and links from way back when promoting/helping ThunderByte AntiVirus (hi Frans Veldman)

Posted by jpluimers on 2026/01/20

Nice memories of the TBAV/ThunderByte Anti-Virus story.

Together with Jeroen Smulders, I was sort of on the sideline in the early days as we both were at the university had access to FidoNet (I as host, other Jeroen as point), Internet, mailing lists and newsgroups.

I used it because it was the fastest Virus Scanner around and a need when scanning all incoming FidoNet data for viruses (I had seen at university what damage a spread could do).

Some VIRUS-L, comp.virus and book links from that past:

Karateka IBM PC Model 5150 Longplay – YouTube

Posted by jpluimers on 2025/11/28

Karateka (which appeared way before the even more famous Prince of Persia which appeared 5 years later) memories of the past, for which I totally agree with the conclusion: the game on Apple ][ was way better:

[Wayback/Archive] 𝔸𝕟𝕒𝕥𝕠𝕝𝕪 𝕊𝕙𝕒𝕤𝕙𝕜𝕚𝕟💾 on Twitter: “@textfiles Jordan’s opinion on the IBM version”

JULY 31, 1986 Just looked at the JULY 31, 1986
Just looked at the “final” version of PC Karateka. It seemed OK, I guessed, except for overall sluggishness, frequent disk accesses, and a few minor graphics glitches. Then I booted up the Apple version to compare… and it was so smooth, it made me want to cry.
The PC version is maybe 50% of what it should be. I can’t even tell these guys s what to fix… it’s a million little things, and they’re just not up to the hassle. That kind of attention to detail is why the Apple version took me two years. This version is probably the best I’ll ever get out of them.

You can play the PC version online at [Wayback/Archive] Karateka IBM Version 1986-01-30 (1986-02-04) (ID 0873) : Jordan Mechner : Free Download, Borrow, and Streaming : Internet Archive

Internal Alpha version (1986-01-30) of the IBM port of Karateka by Jordan Mechner.

It was ported to many platforms, and there was a great documentary too. So there are more YouTube links below than [Wayback/Archive] Karateka IBM PC Model 5150 Longplay – YouTube which has this great description:
