I Got Bit at the Bring 'n Byte Yesterday

I walked in the door and there was this BBC Model B, with a sturdy Watford Electronics carrying case, and it came with a free Cumana 5 1/4" Floppy Disk Drive. Well, I thought I would spend the rest of my life kicking myself if I didn't buy this, and it feels like I'm hitting the reset button on my life and going back to 1982 when my parents bought me my first computer, which was a BBC model A. I used it for graphics programming and learned to write 3D vector graphics programs from Ian O. Angell's book. See Ian Grant's Weather Report August 04, 2022.

Back to England:


It was the HH Tiger, or Tigress, there seems to be some equivocation here, ...

See Alan Sugar at the Cambridge Union for some more context.

So now I am looking up what the BBC Micro's Tube™ was about: What's the TUBE interface of the BBC micro all about? The problem I had as a kid trying to do this stuff on a BBC with 32KB of RAM was that the screen memory took up most of the RAM and left only a few KB for the code, which was all written in BBC Basic.

Now I see I can solve this by fitting a Raspberry Pi Zero with this Raspberry Pi Co-Processor Tube HAT adapter board, for the BBC Micro range Model B, B+ and Master 128.

And it sounds like I will be able to run OpenBSD on this! See OpenBSD News.

Then there is an interesting Raspberry Pi Zero application to resample the BBC TTL RGB signals and display them on an HDMI-connected display: https://github.com/hoglet67/RGBtoHDMI/wiki. So we could probably do this with a Tayloe detector:  101 Things - Raspberry Pi Pico Software Defined Radio.

So I seem to have managed to establish some contact with Cambridge University, at last, but via the sixteenth century. The long way home, indeed! Eng-Fi Short - The Doddleston Messages. Markus just pointed out that the Movie Economy is booming here right now. Trying to guess what they're filming at Vauxhall Bridge today is not easy! I guessed maybe Wasteman or Slow Horses.

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory Illinois. Did
