I’ve long lost the ability to keep track of whatever’s happening in the Amiga community, and personally I tend to just focus on tracking MorphOS and AROS as best I can. The remnants of the real AmigaOS, and especially who owns, maintains, and develops which version, are mired in legal battles and ownership limbo, and since I can think of about a trillion things I’d rather do than keep track of the interpersonal drama by reading various Amiga forums, I honestly didn’t even realise there’s been a development in the Hyperion Entertainment situation.
Hyperion Entertainment is the Belgian company who has been developing both AmigaOS 4 and 3.1/3.2 for a while now, but the company’s largest shareholder, Ben Hermans BV, went bankrupt, causing its shares to be annulled as prescribed under Belgian law. This happened well over a decade ago, but only earlier this year, in January, was the situation resolved for Hyperion: a new director, Timothy De Groote, was appointed by the remaining shareholders, who also instructed Hyperion to continue development of Amiga OS.
In addition, a few days ago, Hyperion released Update 3 for AmigaOS 3.2, adding a bunch of fixes and improvements to AmigaOS 3.2.2. It brings various updates to ReAction classes, a new custom menu for TextEditor users can customise with macros, a new KickStart 3.2.3 ROM, and many more smaller updates and fixes. The update is free for existing users. AmigaOS 3.2 is available for classic Amigas.

Well, this you certainly don’t see every day.
This is a “rough draft” of SDL2 for MacOS 9, using CodeWarrior Pro 6 and 7. Enough was done to get it building in CW, and the start of a “macosclassic” video driver was created. It DOES seem to basically work, but much still needs to be done. Event handling is just enough to handling Command-Q, there is no audio, etc etc etc.
↫ A cast of thousands
The hardest part was a video driver for the classic Mac OS, which had to be created mostly from scratch using the QNX driver as a “skeleton” because it happened to be the smallest one. It works on both m68k and PowerPC as well as on SheepShaver and Basilisk II, and there’s already a few screenshots of it up and running at the link, too. Amazing work, and it opens the door for a whole bunch of especially games to be made available on classic Mac OS.

We’re used to there being an array of high-end microprocessor architectures, and it’s likely that many of us will have sat in front of machines running x86, ARM, or even PowerPC processors. There are other players past and present you may be familiar with, for example SPARC, RISC-V, or MIPS. Back in the 1990s there was another, now long gone but at the time the most powerful of them all, of course we’re speaking of DEC’s Alpha architecture. [JP] has a mid-90s AlphaStation that doesn’t work, and as part of debugging it we’re treated to a description of its unusual boot procedure.
Conventionally, an x86 PC has a ROM at a particular place in its address range, and when it starts, it executes from the start of that range. The Alpha is a little different, on start-up it needs some code from a ROM which configures it and sets up its address space. This is applied as a 1-bit serial stream, and like many things DEC, it’s a little unusual. This code lives in a conventional ROM chip with 8 data lines, and each of those lines contains a separate program selectable by a jumper. It’s a handy way of providing a set of diagnostics at the lowest level, but even with that discovery the weirdness isn’t quite over. We’re treated to a run-down of DEC Alpha code encoding, and should you have one of these machines, there’s all the code you need.
The Alpha was so special in the 1990s because with 64-bit and retargetable microcode in its architecture it was significantly faster than its competitors. From memory it could be had with DEC Tru64 UNIX, Microsoft Windows NT, or VMS, and with the last of which it was the upgrade path for VAX minicomputers. It faded away in the takeover by Compaq and subsequently HP, and we are probably the poorer for it. We look forward to seeing more about this particular workstation, should it come back to life.
