It's time to bring the IIgs back. Maybe with stereo audio this time.

Close-up photo of a PCB from inside the HP 9810A calculator, showing two ceramic packages with gold lids.  Both are 3301A biplor ROMs, but the bottom is HP-badged with HP's in-house part numbering applied.

Some early Intel bipolar ROMs hiding inside an HP 9810A calculator I'm getting ready for VCF Pacific Northwest. The 3301 was introduced in 1969 and holds 1024 bits. Come see the 9810A in action at the beginning of May! vcfpnw.org

I love me some prog, and I have no idea how I managed to completely miss this group. Really good stuff. Same day I picked up Danger Money I also grabbed this (again, on a whim). Turns out to be early prog-ish outfit from Florida. And they're pretty good, too! www.discogs.com/release/1026...

I recently got turned on to UK via a spur-of-the-moment purchase (of "Danger Money") at a record store. Had no idea what I was in for, was pleasantly surprised.

TransBot(tm) says "Trans Rights." (Also all game box art should just be a picture of a hand holding the game cartridge.)

in 2016 a group of strangers in Kazakhstan saved a dog from drowning by forming a human chain to reach him. they just unveiled a statue commemorating the event and I'm genuinely about to start sobbing

Billionaire groupthink is wild; they are now all in a rush to insist they have no inner life. No introspection, soul, interiority, light. They need you to know they are nothing but hungry ghosts, forever consuming, shaping the world to death to rule over a graveyard. They want you just as cynical.

Pretty crazy how important the blockade of a trade route is right now

Our societal systems have elevated to untold power and wealth the most bent and twisted humans among us, people who exploit their fellow humans to such a degree they learn to scorn humanity. Little wonder the tools they build seek to eliminate the problem of humans from the equation of society.

Even if AI could write a novel what problem has been solved? The problem of knowing what you’re reading was written by another person? Who loves reading novels but hates the part where your mind briefly and mysteriously touched another?

You can do the same thing with CEDs as well.

I didn't even have a class with this teacher! But anyway I bought it and now I have made you think about it which is probably more than most people have done about Billy Thorpe today. And really, that's kind of beautiful in it's own stupid way.

PIcked up a small stack of records including Billy Thorpe's "Children of the Sun" which caught my eye only because I remembered a HS teacher *really loving* this album. Why do I remember this? WHY DO I FORGET SO MANY THINGS BUT REMEMBER THIS?

I took a trip on my lunch break Friday to check out what may now be my favorite record store: a local dude who just sells records out of his garage. He's done so for decades. Boomer all the way but in the best authentic hippie way and I love it. The world needs more shit like this.

14 such sheets cover the entire microcode, which implements the entire PDP-11 instruction set as well as front panel operations. (With a lot of help from the hardware, of course.). Each box in that diagram describes what a single microcode word does when executed.

The 11/70 is a fun system to work on. The service documentation is excellent and you get to work thorough fun diagrams like the one below, which traces through all execution paths of the microcode (all 256 words of it).

Traced it down to a faulty microcode ROM (one of several early bipolar 256x4bit PROMs in the system). We had a spare ROM board so we swapped that in; chip-level diagnosis will happen at some later date. The system boots 7th ed. UNIX once again!

Went down to ICM today and fixed the PDP-11/70 system I used to help maintain at the Living Computer Museum back in the day. Any instruction that touched memory would wedge the processor (front panel accesses worked OK). Brought along my KM11 diagnostic set (left pic) to help diagnose the issue.

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.
