I like to do stuff with ancient electronic junk, mostly computers. Sometimes I post pictures of it!

The two quotes from the front matter of C.S. Lewis's "The Screwtape Letters" altered to read:
"The best way to drive out the devil, if he will not yield to texts of Scripture, is to jeer and own him, for he cannot bear scorn." -Luther.
"The devill... the prowde spirite... cannot endure to be corncobbed." -Thomas More.

A photo of an album entitled "PERSONAL POWER through CREATIVE SELLING" by ELMER G. LETERMAN, who is apparently the World's Best-Known Insurance Salesman.  The cover features a nuclear explosion in the background.  Convincing.

This was the secret behind the Akira project, I am told.

One thing the ongoing LLM vibe-coding discussion seems to assume is that what the world needs is more software, faster. What my post presupposes is: maybe it doesn't?

It's 2026 and if you back up your iPhone too many times it will fill up your mac's internal hard drive and there's no reasonable way to specify an alternate location for the backups. No, the backups are not incremental. Enjoy.

I'm fine with Highway Gothic, and I was annoyed when MI started replacing their signage with this abomination.

In that case, yeah. It's not DEC, something third-party, and I have no idea.

It should be much more at the forefront of our minds, the extent to which the most politically activated and politically empowered segment of the authoritarian American cult calling itself "Christian" see the apocalypse as something to hasten, not prevent.

Yeah, I'm the same way, but I've been slowly doing this over the past few months and it's been nice to finally have it organized. Cathartic, maybe. Plus it's given me an excuse to listen to albums in my collection that I've overlooked or completely forgotten I had...

I really value what Mike does in general but his takes here on gen-AI are just incredibly naive; even if "big tech" wasn't involved it's still an incredibly destructive technology based on mass theft. Its only real use is disenfranchisement.

The good news is the head mech on the Diablo (mostly) prevents the heads from crashing into each other during shipping... unlike your average RK05.

The other is a Fortran interpreter (not compiler!) done as part of a master's thesis (PDF here https://
ttu-ir.tdl.org/bitstreams/a5ceda4a-db2d-405b-a5ee-5d608da560a3/download/). I'm working on transcribing this next...

BUS-II is a very primitive monitor system. It can be used to edit memory or registers, and can dump memory to/from tape or the teletype. That's about it. It's also one of only two pieces of real software I know of for the SPC-12.

Screenshot of the emulator running BUS-II; it has dumped a few dozen bytes of memory to the teletype.

Finally had time this week to work out the remaining kinks in the emulation. Behold, BUS-II in action for the first time in who knows how long:

Over the holidays I started work on an emulator of the General Automation SPC-12 minicomputer (a computer I've become lightly obsessed with over the past few months). I transcribed a listing of "BUS-II" (Basic Utility System) from the manuals.

Photo of a vinyl copy of Synergy's album "Computer Experiments: Volume One" from my collection.  Sometimes, I don't remember exactly why I bought a record; this is not one of those times.

Back cover of same.  There is a track listing and what appears to be a listing of 6502 microprocessor instructions for the program "Pink Tunes" used to compose the album.

Not too many albums come with source code these days. For the record, this is the only kind of AI music I'll accept.

IF YOU'RE UNEMPLOYED IT'S NOT BECAUSE THERE ISNT ANY WORK 
JUST LOOK AROUND: A HOUSING SHORTAGE, CRIME, POLLUTION; WE NEED BETTER SCHOOLS AND PARKS.
WHATEVER OUR NEEDS, THEY ALL REQUIRE WORK.
AND AS LONG AS WE HAVE UNSATISFIED NEEDS, THERE'S WORK TO BE DONE.
SO ASK YOURSELE, WHAT KIND OF WORLD HAS WORK BUT NO JOBS. IT'S A WORLD WHERE WORK IS NOT RELATED TO SATISFYING OUR NEEDS, WORLD WHERE WORK IS ONLY RELATED TO SATISFYING THE PROFIT NEEDS OF BUSINESS.
THIS COUNTRY WAS NOT BUILT BY THE HUGE CORPORATIONS OR GOVERNMENT BUREAUCRACIES.
IT WAS BUILT BY PEOPLE WHO WORK. AND, IT IS WORKING PEOPLE WHO SHOULD CONTROL THE WORK TO BE DONE. YET, AS LONG AS EMPLOYMENT IS TIED TO SOMEBODY ELSE'S PROFITS, THE WORK WONT GET DONE.

Photo of the back of a rather banged up copy of the Thin Lizzy album "Jailbreak."  Text reads: 

THE JAILBREAK The warrior locked himself into his video scanner and gazed throughout the Universe . . . until he came up on Dimension 5. 

DIMENSION 5 was now in the hands of the Overmaster, whose lust for ultimate power had become an obsession.  Religion and media were all under his control and computer files were kept on all known living persons within the city zones.

Many were arrested and jailed.

It was therefore significant that The Jailbreak represented a freedom for so many yet to those involved at the time it was a series of events, the outcome of which no-one could have foreseen. The plan was simple. By knocking out the alarm systems in a riot, they then would cause an explosion which would blow half the cell blocks away. Outside help came from an organisation known as Phono-Graphics, who if the plan was successful would eventually capitalize on the whole project.

The night of The Jailbreak all hell broke loose. A Red Alert was issued by the Overmaster himself. Robot trackers, military police, dogs, and all available vehicles were on the hunt. All were caught, except four, who made it to the Rampic Buildings on the south side of the city. It was in these buildings that they broadcast and recorded selected material, some of which still survives today. Through these recordings, they built up a following who eventually took to the streets in what was to become the Final War.

The Warrior had become wear and disillusioned with war, but seeing how the people struggled to be free he knew once again he must raise up his sword...

The music sailed out into the night then upward towards the skies, traveling on that thin border between reality and imagination.

Did *you* know that the song "Jailbreak" by Thin Lizzy has a sci-fi backstory? Well, now you do!

I saw Mystery Science 3000: The Movie (1996) at Studio 28 (RIP) in Grand Rapids, MI, in a theater I didn't even know existed in the multiplex; it was about the size of a large closet. (I later learned a friend of mine saw "Brain Candy" in the same place.)
