Amiga Inc AGA patents?

Compatibility, especially if software likes to rely on magic bytes..

"Hey we assume 0xc0ffee00 is at jump vector 0xdeadbeef so lets jump straight to 0x55891232 because super duper function is there.. !"

At least AROS-m68k is not good enough for the UAE emulator for Unix. But I read that it should work on FPGA Replay.

New driver architecture = incompatible with classic m68k hardware and AmigaOS (ROM).

The last I read on AROS-68k in UAE was that it got stuck on serial or parallell port initialization with a black screen.

How can graphics.library/HID be designed for VGA when classic Amiga in many cases were fully dependent on PAL/NTSC ..?

There are a lot of posts online of people running aros68k in uae in 2012.

If you mean MS-Windows WinUAE..

I'm referring to the AROS implementation of graphics.library, HID is the AROS device interface. By designed for VGA, I mean an actual VGA card sitting in a PC and not the 60hz/31khz video output that it produces.

You must mean AROS on x86 or so.

Two patents remaining in the USA:
Filed-date, Patent-no, Description
1996-09-30 6,484,189 Methods and apparatus for a multimedia authoring and presentation system
1995-01-17 5,574,843 Methods and apparatus providing for a presentation system for multimedia applications

But patent 5,574,843 should not be valid anymore? it has a priority date of 1991-04-26 and it's filed on 1995-01-17 which is 5 months before the change in duration length. That state "For applications filed before June 8, 1995, the term is either 17 years from the issue date or 20 years from the earliest claimed domestic priority date, whichever is longer." The issue date is 1996-11-12.

So it should have expired no later than end of november 2013 ..?

Patent 5,574,843 seems to be about a system to create and present interactive multimedia presentations and coursework. Patent 6,484,189 seems to be about the same stuff. It even looks like a dupe. So the Amiga system itself should now be in the clear and the only remaining patent encumbering would possible be 6,484,189. That should leave projects like Minimig and FPGA Replay completely in the clear?
