Today I learned that Dan Bricklin of VisiCalc fame worked on the arbitrary-precision integer arithmetic package of Multics Lisp: https://www.softwarepreservation.org/projects/LISP/maclisp_family/

Work is over. Time to play.

Voronoi on the C64 from last night was fun, but it had a problem. The problem was random choice of plot meant it slowed down the further it got as more likely to choose existing point. When it got down to the last few, seasons could change before they were filled. I let it run for nearly an hour and it was still not finished.

Modern language I'd use a list and remove points as they are plotted. So you are taking a random point from the *points that remain*.

This is BASIC, and it doesn't have that kind of functionality. So I flipped the idea.

I created an array of possible plot points, and then shuffled that array to randomize the points.

Then iterated that array to plot them.

The end effect was the same - it filled in the points randomly in a predictable time. It completed in around 15 minutes.

I had a nightmare this morning involving EGA graphics and lots of ASCII text... #retrocomputing

Started to clean up the 6502 register/processor status code as it's been annoying the crap out of me. Figured a bit of `ctypes` action would help out with keeping values sane, and would greatly clean up all of the various flag operations. Also helps out with readability. #retrocomputing #emulation #programming

#Atari #8bit hacking today. My #retrotink and #fujinet showed up. Having lots of fun. Trying to get a floppy drive to work. My 1010 won’t read or write, and my XF551 will only run (sometimes) when completely out of its case. More troubleshooting required. #retrocomputing

I like Renesas 7164S20 for #retrocomputing purposes. It's a (small) SRAM chip that responds in 25ns, comes in DIP, and doesn't mind 5V.

Unfortunately, Renesas has announced that it doesn't want to make more of these, or anything like it, anymore. :blobcatsad:

Any recommendation for a similar replacement?

For anyone interested, I'll be filming my next AMOS video this week, looking at Sprites again, but this time specifically Channels and Move commands, with an eye on some animation...

Shaun rediscovered his old Psion 3a PDA and marveled at its still largely unmatched design, build quality, and software:

"I would argue that the Psion was the most Apple-like PDA of all and it was way ahead of the Newton."

Just ordered a keyboard connector fixing kit for it. While it is not broken (yet), it makes removing and re-connecting the keyboard easier with no risk of causing damage.

Oh, and battery and leaking caps were taken care of years ago already. 🙂

Here's my #Acorn A3020. Currently has 2 MB RAM, a 250 MB HDD and a 386sx PC emulator card installed.

Sadly, I somehow blew up the mouse port some time ago, which now needs to be fixed. Also need to get the RAM upgraded to 4 MB.

The rather beautiful NEC PC-8801MC is back out because I’ve found out how to access the BIOS. A few interesting features but the main one being the fact it has BASIC in ROM. #RetroComputing

Dragontorc es uno de estos juegos que dejan un buen recuerdo y son una mezcla entre arcade y aventura con muchos elementos de los juegos de rol.
Ambientado en la Gran Bretaña medieval tomaremos el papel de un poderoso mago que debe liberar a Merlín del encantamiento que lo tiene cautivo tras la desparición de las gemas del Dragontorc, enfrentarse al cambiante brujo Morag y restituir las joyas a su lugar.
80 personajes con los que interactuar en un mapa de más de 200 «habitaciones» y cientos de objetos garantizan horas de juego, conjuros y deducción.
Gráficamente está a la altura de lo que cabe esperar de un juego del #ZXSpectrum con unos decorados efectivos y personajes bien definidos.
Una delicia que recuerda mucho a los gandes clásicos de Ultimate.
Un gran programa que si bien fue alabado por la crítica no fue un éxito de ventas. Merece la pena recuperarlo desde https://worldofspectrum.org/archive/software/games/dragontorc-hewson-consultants-ltd si te gustan los juegos tipo Knight Lore.
¡Disfrútalo! 😃🕹️👍 #retrogaming #rol #rpg #videoaventura #retrojuegos #retrogames #videojuegos #videogames #retrocomputing #arcade

So what did you do on a saturday night ?

Bet you didn't implement a voronoi diagram in a 40 year old programming language... 😂🤦‍♂️

Saw this as a #pico8 tweetcart and my brain was already thinking about putting it on the C64.

Not exactly realtime on a 40 year old #retro computer...

I fired up my old CoCo 1 and it’s finally released the magic blue smoke & gone to join the choir invisible… 😬😩😜

The CoCo 2 I recently bought did not release the magic smoke so at least I have one to play with while I figure out how to fix the older one. Generally it’s capacitors that go IIRC so hopefully it’ll be a fairly simple fix 🙃

I have just killed the last English language account I had left on Twitter.

I created a new profile as @haitchfive for those of you who are interested in retro stuff I used to cross-post pertaining to:

Just came across @mjhibbett & #TheValidators' song #HeyHey16k again; especially the 2004 video clip version with (#Flash) animations by @robmanuel: https://www2.b3ta.com/heyhey16k/ (also archived at Archive.org)
Not sure where the photo used in the animation came from; probably a stock photo. Just crazy to think that even if the photo had been made the same year as the video, that the youngest kid in it would be over 20 years old by now. xD

Following the helpful instructions (https://biosrhythm.com/?p=2688) and copy of the Mini vMac emulator provided by @paulrickards I've now got a #MacOS #emulator running on my Pocket CHiP computer.

It does seem to be pretty responsive though the screen size is a tiny bit smaller than the standard Mac displays, which can cause problems. Games seem to run fine, applications work as well as they would under #MinivMac and I just can't get over seeing the "Welcome to Macintosh" on this screen 🥰​

After 10 glorious years, my #iMac has finally reached the end of its life. A moment of silence for it. In 2013 I bought it maxed out and all my friends called me crazy. Above all, for the ssd which at the time were still very expensive and was a technology that “would not succeed”. 10 years later, all my friends have had multiple computers and I've never had to worry about a thing. They all have ssd drives today. 😆

This is just insanely cool. The Commodore 64 is an impressive machine in its own right, but it takes a special blend of genius and insanity to set one up as a web server.

So I'm now actively looking for a programming job on some kind of bizarre, possibly bespoke or ancient architecture.

Like, the place my Mom works is a COBOL shop on ancient (although well maintained) mainframes.

The code she's been allowed to show me is completely different from what I've done, even beyond that it's COBOL.

Learning something like that would be such a cool challenge!

(And I'd have excellent stories to tell other coders. ;) )

Y'all got any leads?

“On many early microcomputers, BASIC was more than a language — it was also the operating system of the machine, the interface between the electronics inside the beast and the gawk-eyed neophyte at the keyboard.”

Let's try something.

Ask me anything about Medley Interlisp, the seminal software development environment of Xerox Lisp Machines developed at PARC since the 1980s. Ask about how to learn and use it, its history and revival, and more.

What are my qualifications? None, mostly.

But I'm a passionate user. For the past 6 months I've been using the system daily, reading nearly all existing documentation and publications, doing coding projects, and poking around.
