The error I get on both:

A SunGX (CG6). I tried to load MAIKOCOLOR.LCOM, but it failed and goes to URAID. Does the same inside QEMU, which has CG3 instead (with the original firmware to have the 1152x900 resolution).

I guess this might interest @interlisp.org , considering that some of the Schlumberger papers have been mentioned in the LispCore group

Sure, although the first thing I do is reading the manuals. I should join the related groups

Medley Interlisp running on my SPARCstation 10, using Sun Pixrect instead of X11

DVRC @dvrc.bsky.social · 12/08/2026
The issue was much more subtle: I compiled for SunOS 4.0 instead of 4.1.x, which likely has some differences in the way SunWindows events are managed. Now works fine, and I'll have to learn how to actually use the system.

DVRC @dvrc.bsky.social · 11/08/2026
Thanks, I'll try soon. Otherwise I can try on my physical SPARCstation 10. Unfortunately I need an older version of QEMU to run NeWS 1.1 due to a mysterious bug, but hoepefully I have two separated versions installed.

Managed to compile Maiko under SunOS 4.1.4 from the historical archives (used Sybalsky distribution, disabled license check due to issues), since I want to explore the PixRect version. Now I have to figure out how to load the system.

Update: performed surgery on a flex PCB, managing to get a compression connector working again and the ESI graphic board as consequence. Now I'll need a second mobo if I want both the machines to be operative without having to put the mobo in one of the two.

(Warning: heavy flickering near the end) My port of NeWS 1.1 to NetBSD and Linux is going pretty well: events and mouse work fine, psio communication over socket seems to work. Now overlays need to be fixed, because the trash the framebuffer inverting the whole thing

DVRC @dvrc.bsky.social · 10/07/2026
Caveat: the SE graphic board of the Octane (I have another one, not in photo) donated the compression connector to the motherboard, so I've put it in the Octane 2 (which has a VPro V6) that came without it (it was born with a 400MHz CPU). Hoping to find a complete one at a human price...

DVRC @dvrc.bsky.social · 10/07/2026
About 5 years ago my SGI Octane motherboard stopped working, due to bad compression connectors and (later discovered) 3 cracked resistors. Thanks to a friend who provided the stuff now it's alive and kicking again

Rant: before starting a new project or whatever, when you choose a name be sure that is not already taken by something/somone else! Too many times happened that I'm looking for something with a specific name, and cannot find easily because someone reused the name for something else.

First menu on the native server port to NetBSD. It is still quite buggy (no highlight of entries, got also a crash), but it's a step in the right direction.

Some degenerate cases before the fix, just for fun and to show what something apparently trivial can have nasty consequences

After many months I finally fixed a bug in NeWS's CScript that eluded me for quite a lot: arcs rendering. The fix wasn't obvious, but the culprit were the fract multiplication and division, plus a little thing in arcs.c. The new fract routines are basically the ones from Doom's m_fixed.c
CScript output in a SDL window compared against GhostScript, plus filled circle. Cubic, arcs and conics are rendered by dcurvepath.c and arctochain.c, and this hint should have been enough to tell that the bug wasn't there.

to me

Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

Maybe it's my impression, but I feel we are slowly getting in a "revivalism age" in computer science and engineering, rediscovering forgotten ideas and technologies. My hope is that history will be studied to avoid errors and create better hardware/software in general.

The fear is the "unknown copyright status" and that Oracle will knock at the doors of who put online the sources of the server (and Don said on HN that he couldn't put it on GitHub for this reason IIRC). If it wasn't for this I would have put public the repo I have.

OFC I'm stupid and I was byteswapping again the glyph bytes back into the original array instead of using a tmp var to do it. You don't want to see what's going on inside "mem_rop.c" and its CPP macro abuse...

Little progress done with NeWS port on BSD and Linux. 32 bit color has been hacked into in a crude way, and glyph rendering is almost fixed (although some glyphs don't render). Also wrote a very WIP wrapper for libinput (and the Linux/Wayland event model is very unfriendly towards this software).

Reading more Schlumberger papers I learnt that they developed software on Interlisp-D, including OOP extensions (the Strobe language) and an interface builder (Impulse-86). I wonder if any of it survived, in the hope of running it on Medley Interlisp someday.

Today a SPARCstation 10 arrived. After some fighting with the CD drive, I installed SunOS 4.1.4 and NeWS 1.1. Probably this is the first time after years that it runs on Sun hardware. The next step would be making it run on a Sun-3 (emulated or hardware).

DVRC @dvrc.bsky.social · 27/06/2025
The NeWS lore is a rabbit hole: as it wasn't enough a company called Schlumberger developed a tool called "LISPscript", which could either generate Common LISP-PS glue code or compile LISP to PS. They also had an OOP library for CL called "HyperClass". (Pics from the NeWS book and papers).

DVRC @dvrc.bsky.social · 26/06/2025
I'll have to put all the stuff I found on some repo that anyone van clone. Anyway, QEMU 8.0.5 is the last version working for SunOS 4.1.4. NeWS 1.1 comes from Don Hopkins archives, and GoodNeWS comes from Sun User Group 89 tar from John Gilmore

With the keyboard working, now many other things work, including the GoodNeWS environment and the PSIBER

DVRC @dvrc.bsky.social · 08/06/2025
And now keyboard works fine. The workaround wasn't obvious: the patch suggested by Sun works as intended, but the file "repeat.ps" is damaged. Commenting "(NeWS/repeat.ps) run" in the "UI.ps" file did the trick, at the cost of losing key repetition. At least now I can use native terminal emulators.

After fighting with QEMU, I finally managed to compile the sources of UniPress Emacs 2.20. It's really cool to see it working, but I can't type yet due to the keyboard issue that breaks nearly all the NeWS applications.

There are also 4 proposals to abolish part of the "Jobs Act", and to make contractors liable in case a worker gets injured/dies in a workplace of a subcontracted company. From center to right, the political class invited either to boycott, refuse the cards or to vote against.

Font unpacking is done. Now I'll have to investigate why the colormap is wrong, why the text rendering is broken (which also is needed for the cursor).

Had to rewrite cst_readfamily() to correctly unpack the font. It was tedious considering the format is big endian and the members of structs were 32 bit long. Wrote also a little tool to dump font infos. Further work will be needed.

It was the wrong ioctl() (a single letter mistake). Now I'll have to investigate why fonts are not getting retrieved.
