Re: GS/OS System 6.0.2

I can't access the site, but I kinda sorta indirectly know what it's about.  Being able to build GS/OS (and the ROM3 ROM!) from scratch is amazingly awesome.  I can't wait to find time to do stuff with that.

Re: GS/OS System 6.0.2

Oi, here's Google's cached version:

http://webcache.googleusercontent.com/s … clnk&gl=us

What’s new for Apple IIgs System 6.0.2
After 22 years, 2 months, 2 days and 2 hours since System 6.0.1 was released, this is a summary of the visible changes. There have been many bugs fixed and many features added that are not immediately visible–they will enable developers to create better future products.  Be sure to also read the Shortcuts file on the SystemTools3 disk for more information.

Finder (see also Finder Help)
The list is FSTs now includes the RDOS 3.3 name.
You can navigate through the folders hierarchy with ‘Command-Up Arrow’.
about602

Drivers
The Ethertalk driver is now included. This is the driver for the unreleased Ethernet for Appletalk card.

File System Translators (FSTs)
The HFS.FST bug is removed. Your HFS disks are now safe!
Some bugs from the PASCAL.FST were removed.
The DOS33.FST has been corrected.
Tools
The Animation tool (tool037) is now included. It allows fast animation on the Apple IIgs.
The TextEdit bug when more than 1024 styles were used is fixed.
The Font Manager bug is now squashed.
Some bugs in the Window Manager were removed.
QuickerGraph that accelerates some drawing routines is now included. This program is unfinished and your system may become unstable if you install it.

What’s next?
This is a proof-of-concept update. Updating the System Software can be done! There are other bugs in the System, let’s correct them for a 6.0.3 update in a month or so…

Re: GS/OS System 6.0.2

Yeah, heard about it on the Apple II Enthusiasts group over at farcebook.  Bill Martens posted the link there.  Downloaded both versions, even though I'm currently IIgs-less.  Sold mine to Charles Tjalsma last month.

Re: GS/OS System 6.0.2

awesome… yeah i am going to download that and put it on my floppy emu and have a dedicated emu just for IIgs / smart port and 3.5" images too.

Re: GS/OS System 6.0.2

This is pretty super exciting.  I guess the GS/OS source is available, and they've got it building from source, and fixing bugs.  I've never been a huge GS/OS fan, but this is pretty much holy grail territory.

Re: GS/OS System 6.0.2

Indeed!

The next step would be to start modernizing it and adding new, more modern features.

Maybe even porting it to another architecture, though this would probably be quite non-trivial, I imagine.

Now if someone could get a hold of the Classic Mac OS source code (I've read of rumors that a partial copy of System 7.1's source is floating around somewhere) and do something like this, then we could have preemptive multitasking and protected memory at last! (this would probably be impossible without a complete rewrite, but it's still a fun thought!)

They could still at least tweak a few things and fix a few bugs, anyway.

Re: GS/OS System 6.0.2

It would actually be relatively easy to add protected memory, at least, to the old Mac OS kernel. The problem is that many apps won't work in that scheme.

Re: GS/OS System 6.0.2

is the IIgs locked in at a certain resolution?

Re: GS/OS System 6.0.2

ClassicHasClass: Oh? Well, then, I guess it can be done!

Except no applications will work. Why?

Maybe (hypothetically) one can provide some sort of compatibility layer, wherein a standard, non-Protected-Memory-aware program can run in an expected environment. Sort of like the application heaps, but better. Make sense?

That's been done, it's called Classic Mode. wink

Re: GS/OS System 6.0.2

Yes, I know that, but for the Improved Classic Mac OS on 68k Macs (upon which the classic mode you're referring to will not run).

What I'm imagining would be somewhat like Copland, but for 68k (and more of an extension to the original Mac OS, rather than a complete rewriting of it, as was the case with Copland).

Come to think of it, what if somebody found the source code for Copland? That would be FANTASTICALLY incredible, as that OS had a lot of potential, but poor management kept it from getting anywhere.

Re: GS/OS System 6.0.2

Except no applications will work. Why?

Among other things was the overreliance of Managers on shared memory (QuickDraw comes to mind, but there are others). Most apps just expect to be able to write to certain globals. You could improve this by allowing some areas of memory to be writeable to all, but there will always be something that will break under those conditions.

Carbon's advancement was forcing these kinds of APIs to use opaque allocations and special system controlled accessors, but the app had to be written for that, of course.
