December 14th, the end of Yahoo! groups

Oddly enough these things have been going on since 2001, and have been curated gardens instead of the mess that is usenet (which is still operational!), or private mailing lists.

The 2 that Im on are the Hercules 390 group which moved to While other groups like H390-music (MUSIC/SP the Canadian mainframe OS with internet hooks) that sadly died along with it’s author, is probably going to be purged from the internet.

Along with other things like pdos, or even the board game Supremacy.

I don’t know what the answer is, other than to always have downloadable mailing list archives, and never trust a single place. So much stuff is deleted to save trivial amounts of space, and neither corporations nor government institutions can be trusted to maintain anything.

Thankfully there is, but who backs them up?

Confessions of a paranoid DEC Engineer: Robert Supnik talks about the great Dungeon heist!

What an incredible adventure!

Apparently this was all recorded in 2017, and just now released.

It’s very long, but I would still highly recommend watching the full thing.

Bob goes into detail about the rise of the integrated circuit versions of the PDP-11 & VAX processors, the challenges of how Digital was spiraling out of control, and how he was the one that not only championed the Alpha, but had to make the difficult decisions that if the Alpha succeeded that many people were now out of a job, and many directions had to be closed off.

He goes into great detail how the Alpha was basically out maneuvered politically and how the PC business had not only dragged them down by management not embracing the Alpha but how trying to pull a quick one on Intel led to their demise.

Also of interest was his time in research witnessing the untapped possibilities of AltaVista, and how Compaq had bogged it down, and ceded the market to the upstart Google, the inability to launch a portable MP3 player (Although to be fair the iPod wasn’t first to market by a long shot, it was the best user experience by far).

What was also interesting was his last job, working at Unisys and getting them out of the legacy mainframe hardware business and into emulation on x86, along with the lesson that if you can run your engine in primary CPU cache it’s insanely fast (in GCC land -Os is better than -O9).

The most significant part towards the end of course is where he ‘rewinds’ his story to go into his interest in simulations, and of course how he started SIMH when he had some idle time in the early 90’s. SIMH of course has done an incredible amount of work to preserve computing history of many early computers. He also touches on working with the Warren’s TUHS to get Unix v0 up and running on a simulated PDP-7 and what would have been a challenge in the day using an obscure Burroughs disk & controller modified from the PDP-9.

Yes it’s 6 hours long! But really it’s great!

WRP 4.0 Preview

(This is a guest post from Antoni Sawicki aka Tenox)

Welcome a completely new and absolutely insane mode of Web Rendering Proxy. ISMAP on steroids!

While v3.0 was largely just a port from Python/Webkit to GoLang/Chromedp, the new version is a whole new game. Previously WRP worked by walking the DOM and making a clickable imagemap out of <A HREF> nodes. Version 4.0 works by using x,y coordinates obtained from ISMAP to perform a simulated mouse click in Chrome browser. This way you can click on any element of the page. From annoying cookie warnings, to various drop down menus and even play some online games. Also pagination has been replaced with a clickable scroll bar.

Enough talking, you can watch this video:

Or download the new version and try it yourself!

Please report bugs on Thank you!

WRP 3.0 Beta ready for testing

(This is a guest post from Antoni Sawicki aka Tenox)

I have released WRP 3.0 for testing. It’s currently a browser-in-browser server rather than a true proxy, but that’s in the works. Please try it out and let me know. Usage instructions are on the main github project page.

Today using trickery I was able to login to my reddit account from Mosaic:

Update: just added the missing image quantizer so that the color number input box actually does something useful. Now you can browse porn even with 16 colors:

WRP Runs on Windows

(This is a guest post by Antoni Sawicki aka Tenox)

Thats right, the new beta version of Web Rendering Proxy runs natively on Windows. Single EXE, no libraries or dependencies required. Only Chrome Browser.

I took a Internet Explorer 1.5 for a spin today while WRP was running on my Windows 10 PC. Worked just fine.

I have added Prev/Next buttons so that you can easily “scroll” through long pages.

ISMAP support has been added, proof:

You can download a preview build on github.

Web Rendering Proxy – Overdue Status Update

(This is a guest post from Antoni Sawicki aka Tenox)

There hasn’t been a major update to WRP (Web Rendering Proxy) in 5 years or so. Some new features have been added thanks to efforts of Claunia but the whole project was mostly impeded with mass migration of the whole Internet to SSL/TLS/https. It does semi work somehow thanks to sslstrip but the whole stack is an unmaintainable pile of crap which I’m not going to update any more.

A new rewrite from scratch is well under way. This time written in GoLang and using Chrome DevTools Protocol. Things should be much more stable and future proof.

Far from complete but I have a fully functional prototype now working in just under 100 lines of code:

UPDATE 1: You can play with it if you want. Please do not submit any bug reports just yet, as this is just a development version. Note that WRP is currently not a true HTTP proxy but rather browser-in-browser. Proxy may be supported later.

UPDATE 2: As of today online setting of size, scaling and scrolling is supported. I’m specifically happy about the scrolling feature albeit it probably needs a better user input, like prev/next page.

Windows version still doesn’t work due to an upstream bug, which is probably easy to fix.

ISMAP is currently in development.

French national Internet Referral Unit tries to shutdown

Count on un-elected technocrats trying to ruin awesome resources with their kanagroo court style operations in their little backwater nonsensical nations.

Good grief.

I should step up my uploads. I did add my NetWare 3.12 disk sets, Citrix Multiuser 2.0 and NeXTSTEP 3.3 CISC stuff.

Comcast Router and SNMP

(this is a guest post by Antoni Sawicki aka Tenox)

This is a lame duck, low effort post. And if you already know it it’s obvious. However this question seem to be asked a lot on the intertubes. I hope it will help someone else, as there is no good readily available answer out there.

Problem: I wanted to have SNMP on my Comcast/Xfinity router so I can monitor current bandwidth usage.


  • Possible to enable on vanilla router? – Nope
  • Do 3rd party, Comcast compatible routers do? – Nope
  • Can you SSH or hack in to the router to do it? – Nope
  • Can you load custom / hacked firmware to do it? – Nope*

Nope or very hard / unsupported.

So is it possible at all? Yes, but with a separate device. Comcast/Xfinity routers have so called “Bridge Mode” which essentially turns them in to a DOCSIS modem without router / firewall / wifi access point.

Solution: Turn on Bridge Mode in your vanilla Comcast router and buy a WRT firmware router / access point. I got Linksys AC3200 for $99 on Amazon. Ssh to the router and run: opkg install snmpd


Using UnixWare 2 to Set Up a Web Server: A Case Study

I stumbled across this ancient page, and thought it was so dated that I had to share it.

Bravo on MicroFocus for keeping it up.

Original UnixWare website over at Novell

It’s kind of cute they ran it all on a couple of  Zenith Z-Server LT P60E computers, which have 128MB of RAM and 5GB of hard disk space, and 2 T1’s.

Even more shocking to me is that their LAN was just 10Mbit, which for a Unix/Networking OEM you’d think they would be on the edge with new tech like 100Mbit Ethernet, or more complicated/fast technology like ATM or FDDI.  Heck even 16MB Token Ring.

Novell home page circa 1995

It’s amazing the tiny screens we had back then.  I can still remember the 800×600 debate, as people even in the later 90’s were pushing for megabyte pages, and ludicrously big real-estate.

As always it’s funny how dismissive they were of Linux:

Linux didn’t have good support and we were concerned about its ability to perform under heavy loads

And of course how they dismissed Windows NT:

Windows NT, on the other hand, handled the chores okay, but it lacks a wide developer base. As a result, few tools are available for working with Windows NT. 

Naturally the tell is that they didn’t load HTTPD directly on NetWare as it was dead with the arrival of Windows NT.  And UnixWare and commercial Unix was also dead with the utter stagnation of SYSVR4.

UnixWare home page

And the product page for UnixWare was that awkward 50’s stock images, with too much red/pink that was all to common for Novell back then.  It’s almost laughable that they considered being able to run on the i386 as being ‘portable’ but for whatever reason they never could port UnixWare to any other platforms.  When they sold off UnixWare to Caldera they failed to do anything with it, and famously turned to lawsuits to attempt to recoup their money from the botched port to the Itanium that was done with IBM’s ‘help’.

UnixWare was going to lead the charge in the post SYSV world, but it’s constantly being sold, and pushed to do different things and fit an increasingly smaller role just cemented the demise of SYSV.

And of course marginalized and almost forgotten, NeXTSTEP would go on to be the #1 commercial UNIX in the market place.
