“Things Have Changed” – Bob Dylan (1999)

“Everything, still remains the same”
“(Sittin’ On) the Dock of the Bay” – Otis Redding (1967)

tl;dr embarking on quantifying meaningful indicators of small computer system performance over the last three decades

In graduate school and subsequent professional work, analyzing performance of computer systems was often my primary effort, including much of the software I wrote, and my first three books. Years ago I pontificated about Meaningful Indicators of System Performance, surveying the (mostly) synthetic benchmarks in vogue in 1990. I was also active in the formation of the Business Applications Performance Corporation. (more…)

[koko] Dell Unix sustainable!

“The only thing I knew how to do
Was to keep on keepin’ on like a bird that flew”
(1975) “Tangled Up In Blue” – Bob Dylan

tl;dr with 86Box, obsolete hardware not needed

[update December 2021: files for 86Box install at]

[update February 2024: [koko] knowing and accepting limitations]

With prodding and help from Antoni Sawicki, and bits of help from others, I’ve been trying to get Dell Unix to be sustainable on modern hardware. I’d succeeded in building our SVR4 from the last sources on turn of the century and older hardware. VMware and VirtualBox options seemed plausible, but so far we haven’t gotten those to have minimally useful networking, only had slow SLIP. on Dell Unix on 86BoxThough it has been around for years, and used by Antoni before, I was unaware of 86Box until late last year when Antoni posted about it, particularly: Dell Unix on 86Box “Today let me present Dell Unix more properly, with 1024×768, 256 colors video and proper networking using emulated VGA and NIC.” That post illustrates Mosaic, FrameMaker et al.

That left the question “What about using Dell SVR4 on 86Box to build SVR4 from the sources?”

[koko] (welcome to …) eight Jurassic O.S. on 1992 Dell 486D/50

“Genghis Khan and his brother Don
Could not keep on keepin’ on”
(1971) “You Ain’t Goin’ Nowhere” – Bob Dylan



tl;dr multibooting a 1992 Dell 486D/50
   WFW3.11+Win95+Win2K+DellSVR4+NEXTSTEP+RedHat5.2+OS/2 3.0+OpenBSD2.5

(Maybe it should be tl;dw — didn’t watch — the video is long.) This post is intended to both be more accessible summary and provide details that are not in the video.

As part of prolonging JAWS, I bought a 1992 Dell 486D/50 on eBay for $99.99. Though lacking the JAWS graphics memory, EISA and some custom Dell VLSI, that machine is otherwise similar to the JAWS machine, sharing chassis, power supply, SmartVU, probably other items I’m forgetting. The seller didn’t think the 486D/50 was working but I thought I could at least use it for the chassis, etc.

Over the last couple of months, I’ve made the 486D/50 into a robust machine, capable of multi-booting all of the 1990s operating systems listed above — three major Windows versions, OS/2, two competing Unix versions, NEXTSTEP, and Linux. The video demonstrates using a Web browser in all eight environments. I could probably have used the Mosaic browser on all eight, did use Mosaic on most, but (of course) used Tim Berners-Lee original browser on NEXTSTEP, and chose to use Netscape 3 on BSD Unix and Linux.


koko: reviving timbl’s WorldWideWeb browser

Monday, July 1st, 2019


April 30 [1993]: “Date on the declaration by CERN’s directors that WWW technology would be freely usable by anyone, with no fees being payable to CERN. A milestone document.”
December 25, 2021: Happy 31st birthday WorldWideWeb – the first browser!
July 1, 2021: Sir Tim Berners-Lee’s World Wide Web NFT fetches $5.4m at auction while rest of us gaze upon source code for $0
June 15, 2021: Web inventor Berners-Lee to auction original code as NFT

“Genghis Khan and his brother Don
Could not keep on keepin’ on”
(1971) “You Ain’t Goin’ Nowhere” – Bob Dylan

With working NEXTSTEP 3.2 in hand, I wondered if I could find sources for the original browser that Tim Berners-Lee wrote when he invented the World Wide Web at CERN, and if I could, could I get that browser working. Success!

NeXT, give Steve a little credit for the Web

The news reports and tributes following Steve Jobs’ passing this week have been dramatic, both in quantity and in degree of regard and respect. Today in the Wall Street Journal’s Steve Jobs: The Secular Prophet there is an extreme example, with allusion to Socrates, the Buddha and Emerson, and comparison with Martin Luther King Jr.
