Re: AON, project in progress

Thanks for your hard work, Shiru. Any chance of migrating from VCL to CLX though, so the emu could become portable?

Re: AON, project in progress

At this moment I'm on the 'make it work' part, before 'make it pretty'. I need to figure out lots of details to create faithful emulation that is useful for new developments. VCL just helps me to speed this process up, as I know VCL very well, while I don't know anything about CLX (yet). Sure, eventually I'll put some time to make it more accessible and useful.

Re: AON, project in progress

Got yet another unit, nothing to show really, but it is an old large Z80 board build with one of the oldest firmwares - Arctur 36. Tried to find this one on the webs, and alas, all dumps is now gone. So I dumped it (it is very different from all others), the ROM was unstable, so I had to stare to the hex compare quite a bit. This way I figured that I may seek for hidden messages in firmwares. And there is indeed some! Here is the list for your digital Indiana Jones pleasure.

Re: AON, project in progress

Hmm, very intriguing. So there was some Ukrainian involvement.

Re: AON, project in progress

Another fun fact gained by the means of digital archeology. I was messing up with the firmwares that featured the sampled speech stuff, attempting to make a sample decoder. They use different formats, I did only one (4-bit samples at 5000 Hz), other ones is well distorted, but recognizeable. I learned that there was the first version to feature voice, it had male voice that only spelled a few numbers and short messages, then there was the second one (Selena), it had best quality female voice. Latter has been ripped, downgraded, and reused all across other firmwares. Derivative versions has varying sample set, some say tens and hundreds, and extra messages, some not.

The fun fact is that one of the firmwares, the only one (of those I checked so far, at least) that features good quality female voice, also has an angry male voice clip in the middle of the data: FUCK OFF! (in Russian)

That made me remember that an urban legend circulated at the time, that if you enter some secret code, you can blacklist a number with such a message played to the caller. Turns out it wasn't really a legend.


Re: AON, project in progress

Ha ha epic demo, mate! https://www.youtube.com/watch?v=3db3HIQuGds

Re: AON, project in progress

Thanks! At least some real outcome of messing around and flooding this thread with this stuff. Also helped to improve the emulator. Also my first 'full' demo since 1997 when I first learned what a 'demo' is.

Re: AON, project in progress

Great demo. Glad you perfected your code, like the tune too smile

Thanks for the greet smile

Re: AON, project in progress

Thank you, guys.

Should note that this was a side step related to the original intents. I did not use any software 1-bit synthesis in this demo, it is just the plain single channel 8253 music (very much like classic PC Speaker), created with PCSPE. Truly 1-bit and truly monophonic, though.

Still going to do a music sequencing, or a performing software perhaps, using this platform, with a custom 1-bit engine.

Also thinking on creating a cut down replica version of the schematics, omiting all phone line related stuff, and a PCB layout, so more people can get the thing without relying on buying old hardware overseas. The device is quite easy to assemble, and does not need rare parts (the obscure single piece LED display obviously has to be replaced with some modern ones).

Re: AON, project in progress

A ton of distractions happened since, but English translation of the making of the demo is finally here: https://habr.com/ru/post/486010/

Good read, thanks!
