@anne Bletchley Park is alright, but it's not especially technical in content - it's very much WW2-focused and a bit jingoistic. Look what Great Britain did, we won the war!
The National Museum of Computing is far more technically interesting and it's independent of Bletchley Park, it just has its building on the same site. It has a working rebuild of Colossus and a lot of volunteers who used to work on the original machines and will talk through them with you, for instance.
Welp, time to fix Derby Day again.
This horsey pinball dates from 1967 and features an elaborate backbox animation of six horses, each of which move individually along a track when the ball hits certain targets. Getting your horse all the way to the finish line enables higher scoring.
As you can see, we had some problems at ReplayFX. I'll transcribe the out-of-order sign in the next post, as it's a long one.
Heather Meafield and Earl Dayles, both alumni of the Caltech Spaceflight Laboratory and equally instrumental in the design of the AGC, introduce and examine the theories and implications of the Moonbeam anomaly. Incorporating recently declassified data, the pair draw parallels between Moonbeam and a variety of other well-studied computer consciousness incidents. These include the 1970 PDP-11 transmogrification events, the Soviet schema bomb, and the disappearance of Konrad Zuse.
Seven Puzzles You Think You Must Not Have Heard Correctly

In collections: Attention-grabbing titles, Puzzles
A typical mathematical puzzle sounds tricky but solvable — if not by you, then perhaps by the genius down the hall. But sometimes the task at hand is so obviously impossible that you are moved to ask whether you understood the problem...

Best way to compute Pi on such a machine??? (I don't mean 355/113!)
Photos of the @SDF exhibit at the #Vintage Computer Festival #vcfwest happening right now at the Computer History Museum, Mountain View, CA ... thanks froggyme! Today's the last day so if u r in the area, why not drop by!
For more info on the event, go to:
We will try to get froggyme to dial the SDF VoIP Conference Bridge (ext. 1088) and stream the sounds coming from the venue into http://aNONradio.net from 19:00-19:29 UTC & 23:00-23:59 UTC so call in or listen ✌️
"Antarctica’s problem is that you’ve run as far you can to “escape”. Once you get to Antarctica, there’s nowhere further to go. Then, winter, with no flights for nine months. When things start going wrong again, because the common denominator is *you,* you’re trapped."
"... as the months wore on, the alcohol consumption not only increased in quantity, but in alcohol per drink. By the end, I was tossing out 4-7 empty liquor bottles a night for 6-12 people."
@EdS @emilio A related Life project: A group of hackers from codegolf.stackchange.com accepted the a challenge and spent ~2 years to develop a 16-bit clockless RISC CPU inside #GameOfLife to build a Tetris machine.
Nevertheless, the size of this computer is 2,940,928 x 10,295,296, not sure if can be ran on a retrocomputer... It also needs a extended Game of Life engine to write keyboard input directly to the RAM section.
Without releasing its magic smoke, the CPU board comes alive! #Z80 starts to fetch, decode and execute instructions as expected, although there's nothing to fetch so far.
My breadboard prototype reached the same first step in April 7th. It's a full cycle redoing it on a PCB four months later, learned a lot about 8-bit machines in this process, will continue updating the thread.
Machine Code for Beginners
Forth: A Weird Programming Language. Here’s Why You Might Love It Anyway.
I've created a github repo for "f68k", an Forth 83 System for m68k computer (Atari ST, Amiga, Sinclair QL and OS-9). I've merged back the Amiga and Atari ST files.
This Forth system is the ancestor of f68kans, an ANS-Forth version of the same system:
