Which brings us to the fact that how much time has passed which brings us to the fact that we are really getting old grin

 Re: Digital System

Indeed, that appears to be the author's earliest work. What's odd to me... that honestly, for 1988, this is excellent stuff. If one takes a closer look at what the utility is doing, the screen, the code, and even the font(!!!) is at $0800 (to leave room for the digi). That's honestly not that trivial to code, especially without modern cross-assemblers. So yeah, I'm geeking out a little.

To me, this shows a deep understanding of code and the machine. Therefore it's even more surprising that the author doesn't recall anything about these utilities (they mentioned that seeing this was news to them) happy

Therefore, Digital System is the oldest known release by Callisto!

I understand and can speak a bit of Russian... A learned it for 4 years in elementary and then life threw it at me again in adulthood.

Nice detective work btw Csabó! happy

LOL, I learned for 8 years Russian, but no way I can speak or understand anything... Unfortunately.

We were the Hungarian Resistance! happy

Wow @Csabo, this is a pretty awesome work! The ancient Hungarian scene of the Plus/4 is still far from being fully rebuilt, and this is a fundamental tile to the whole scenario's mosaic.

In this precise moment, I'm reading a precious book called "Crackers", a first of what seems to flood into a triad of publications overall, aiming expressly to the Atari ST scene, and this text finds its core generator from the memories of the French demoscene (does a French demoscene really exist? Wow!). Taking count of this, I'm sooo surprised about a certain lack of interest about OUR scene, despite of the fundamental role that it got – in larger or thinner rate depending by our personal stories each of us – into the lives of any of us. Others mutate these infos in pure gold like the book I cited above, possibly we might have a feeling of negligibleness about our story, which looks like a WRONG sensation to me!

Short note about the Russian language taught in Hungary at that time. Years ago, @KiCHY ignited a wonderful project about a C16 game with classy minimal graphics, hence I drew a hires title picture in order to make it very saving once packed. The global style of the graphics suggested me to give to the titlescreen – and as a consequence, to the game's plot – the look of an imaginary Soviet cartoon from the 60ies, also by adding a subtitle to the game written in Russian. I loved that idea so much to push it to the author (a mistake I didn't after, and I won't in the future, repeat again!), but KiCHY absolutely didn't like that, and didnt' like it in a way which can be described as "historically painful". In result, he dropped, me and the project, shame on me and my silly inappropriate insistence!
Service note: KiCHY let's step back to that game, we can still do that! ;)

 Digital System

Today's Demo of the Day is Banzay Digi. @Chronos made a funny observation about it: the author greeted their Russian teacher, along with the usual sceners (TCFS, Pigmy, etc). (BTW, at that time, many of us - including me - were learning Russian in elementary school, it was mandatory.)

The demo is signed as "WRITTEN BY DGS". I figured I would look into this since I've been in contact with DGS before. He quickly responded; but alas, he did not write this demo. The site had that wrong, oops!

I kept looking at this and found some other interesting stuff. When reset is pressed, there's a second signature: "DUGO". I concluded that this is another person, who just happened also to use the same handle (perhaps Dugo Software). I added all these findings to the demo's page, and I kept looking. One thing that I want to note: this (currently unknown) scener, let's call him Dugo for now, sends an unkind message to another dude. Their name is pretty unique, I found a LinkedIn and a FB profile with it. If anyone would be up for it, they could try to contact them on the latter platform, and ask if they perhaps remember a friend from elementary or high school nicknamed "Dugo". Might be worth a shot happy

I found some fragments, with Callisto's name, and referencing something called "Digital System". I did NOT recall that name, but after a quick search, Tarzan's New Catalog 2 provided a hit: there, it is indeed listed as a utility. I disassembled the code, and saw that some code was clearly "readable" (it made sense), but it was at the wrong location. Shot in the dark: let's relocate it... It almost worked, as far as having a working IRQ.

More digging, and I realized that I was looking at packed code. Since it appeared to be RLE, I figured i was worth a try to see if I could manually unpack it. After a couple of tries, I had it! Two command bytes are used: $BF (length) packs that many $00 bytes, and $CF (length) (byte) packs the given bytes.

After unpacking and relocating the code... it miraculously started up grin


I did have to fix a few bytes manually, but otherwise colors, font, and code, all fell into place. This has not been seen by anyone in 36 years grin

Unfortunately it doesn't fully work: the code is waiting for a keypress, but then it crashes. Still, I'm very happy with this outcome: a bunch of stuff got fixed, and we have one new entry (even though it's not fully complete) in the database.
