John Sobanski revisits the Apple II programs he wrote in BASIC four decades ago as a 9-year-old. They're typical of the code many of us wrote back then when learning to program, to experiment with and combine language features to get interesting results.

#appleII people, would anyone be able to dump the ROM of their MouseCard? We're having doubts about the existing one in MAME. (https://github.com/mamedev/mame/issues/13598)

Registration is now open for INIT HELLO, the new Apple II conference to be held at the System Source Computer Museum in the Baltimore, MD area.

I'll be there - just registered. I hope you're there too!

Found a super top secret military transmission. Who better to decipher it than my green glowing Apple IIe from 1983? What could the message be?

Oh look - it's a new blog post, an introduction to the USCD p-System Editor, *written on* the UCSD Pascal Editor:

Yes, this means that my #Rust #psystem utility can successfully copy files off of the emulator disk image, and convert them into Mac-formatted text, from the frankly bizarre format that's native to the text editor.

These last days I've actually implemented the things I wanted to do since a while in my 6502 debugger, and it now counts cycles with page-crossing penalties, resolves y-indirect "($nn), y" memory accesses, warns me when a function returns with a stack imbalance.

It can now also exclude files or segments from the symbol-resolving, which is good when your projects have nine opponents sharing the same segment at different times.

I'm impatient to use all that extra help on my next project!

It's midnight, but I am *finally* "listing" files on an Apple Pascal formatted disk image from my Rust-based filesystem utility.

Which means - I have understood the disk format well enough, and interpreted the filesystem structures properly.

Maybe tomorrow, I can move on to getting some files on/off the disk images.

Okay, testing @MuseumJoe 's A2Vidga with Mario Bros on my Apple IIe. Composite output first, VGA output second. The latter is so much cleaner than composite.

Edit: 80 column text is also unsurprisingly very sharp. Very nice card, get it if you want VGA for your Apple II. https://jcm-1.com/product/a2-vidga-apple-ii-vga-adapter/

Question for retrocomputers apple II people. If you could buy any apple II but only one, which one do you choose and why?

Thanks in advance for your replies & comments. I also greatly appreciate boosts for reach.

#retrocomputing #apple2 #appleii

I didn’t game on a II much in the double hires days… my school had already switched to a IIGS. But I’ll admit the later releases look so much better. #apple #appleii

Powering the Apple //c with a 15v source and a bespoke USB-C power adapter.

This //c has been setup in more places than any other system I own. Here is the latest, atop a small shelf system in the Byte Cellar.

By the way, do go take a look at http://jcm-1.com as there's a ton of cool retro stuff. The A2DVI is one of those things and likely is a better choice for most as it's HDMI compatible.

But I chose the VGA version because I happen to have a VGA-only 5:4 LCD monitor and because VGA was released in 1987, when the Apple II line was still heavily in use - making them contemporary.

Packaged has arrived - it's an A2 Vidga VGA card for the Apple II by @MuseumJoe.

Looking forward to testing it out!

the ending to Zodiac Castle, where I outwit the parser (mostly) via an absolutely absurd observation about the exact character length of nouns

also, more tiny dragon antics and an endgame involving death by black magic

Added the special "Chat Mauve" double-high res mode for the #appleII in my MII #emulator this one allows alternating between color and monochrome mode, it's quite neat. #retrogaming #retrocomputing

One of the things I would have loved to have for my Apple IIe clone when I was a fairly broke teenager was a Mockingboard card.

Really thinking of of getting the ReactiveMicro clone, but I'm wondering if I should wait for a Pico-based re-creation first (something similar to the PicoGUS). Anyone know of if people are working on such a project, because I wouldn't mind sending them money once they have a product.

At All the Adventures, Zodiac Castle continues, with ornery secrets being hidden by an even more ornery parser.

Also, killing tiny dragons.
