on that note: i just booted up an A500 that I bought 20 years ago for the first time
i never had bothered with the machine because I preferred its older brother A1000 for the case design and overall style
as it turns out, the previous owner installed a 2MB RAM + clock upgrade, as well as an internal HDD in this A500! i had no idea they were capable of having internal HDDs D:
i soldered a new clock battery in, and it's running like new. pretty amazing machine for its footprint.
@vga256@vga256https://RetroRewind.ca has plungers for the Mitsumi style keyboard. For a spring my advice is to reach out to us through the Contact Us link on the website and we’ll see what we can do. 😁
too bad I never owned a MegaDrive in the 90's. Was too much into the #Amiga , which I do not regret, as it created me the person I am (as a software engineer/engineering manager). Though, I would wonder what this would have been if I had a Sega instead... ;-)
I've just watched the #Amiga demo HAMazing by Desire and I want to say a few words about it. The first ones are: it's insane what hardware that's almost 40 years old could do. It blew my mind as a kid and rightly so.
The demo is all about leveraging HAM mode, which allowed you to display up to 4K colors simultaneously. Let me explain how that worked and how remarkable this demo is. 🧵 1/6
The original Amiga OCS chipset had a palette of 32 color registers which was the maximum that could normally be displayed at the same time, using 5 bits per pixel to index them plus 1 bit that could be used to halve the brightness of the color.
In Hold-And-Modify mode these 6 bits weren't used to encode a color, but a command. You could set the value of a pixel from a 16 colors palette, or copy the color of the previous pixel while changing one of its components. 2/6
This was achieved via the Copper - one of the Amiga coprocessors - and is not an easy trick, requiring careful coding and precise timing.
Anyway, this demo is fantastic, the authors have amazing skills and the hardware was so much ahead of its time. And if you want to read more about it Wikipedia has a very good article about HAM: https://en.wikipedia.org/wiki/Hold-And-Modify 6/6
As a youngster, I made my first Deluxe Paint pixel art on an Amiga 1000 in 1986. Coming from a Commodore 64 with a fixed palette of 16 colors, the Amiga was revolutionary at the time.
I went on to use "DPaint" professionally on a daily basis for around 10 years, creating pixel graphics for games, advertising agencies and television shows.
@didier I don't see it actually manipulating the return address, so it might be portable (perhaps to 1.3+ at least). I've never seen this, but it seems when you return 0 from the bootblock, the bootstrap code will just continue booting at the code pointed by A0. That is then set up by the shown code, which read sectors 2..9 (offset $400-$1600) to be executed there. So they just needed a longer boot code it seems
Thanks to the lovely request from @vanacksabbadium I present to you my latest work.
Feast your eyes on the Shadow of the Beast 3 banner. 😊
I might actually do the banners for the part 1 and 2 as well, so stay tuned. 🙂 #amiga#art#retrogaming#oldgames
I have a really big wish to create #Amiga related videos on YouTube, but I am having a hard time figuring out the required free time the extra production will take (I already have one YT channel). And everyone told me not to mix topics on one channel because viewers hate that.
@OnceUponAGoblin did you see my Linux channel? What worries me is that Amiga content isn’t a good fit in there and that it would ruin my Linux channel growth and that I should put Amiga content in new/different channel.
@dentaku Yes, my original cases for the Rev5 boards all have only the Chickenlips. But the A1200.net cases only have this style indentation for a long badge.
