@asymetrix

As in how QNX is realtime? No, not without rewriting it from scratch. It does have things like IPC etc. which take very little time and could sometimes be considered realtime, but the bottom line is that there are never any guarantees made regarding timings or availability. Does it really need to be though? No other desktop OS does realtime because there's basically no need.

@wawa

I find myself in brief agreement with wawa , there is no point in the fine discussion of the number in the name, or the letter much for that matter, AmigaOne needs to be included for branding purpose but after that I don't really care if it the called the "AmigaOne Zebra Kitten XTY1972.z"

AmigaOS has been "near realtime" since it's beginning.
That's one of the reasons why Amigas were used by military or NASA.

With x1000 one can reach HARDrealtime because of the xena running your custom I/O.

Care to back up that statement? NASA used it because it was easier to develope hardware for it which they used on a large mission status display. Impressive sounding, yes, mission critical or anything on the scientific end, no chance in hell.

I'll be interested to hear which military used it for what purpose, other then for video toaster capabilities.

British Army used it for SCALA presentations on battlefield tactics at Sandhurst Royal Military Academy. I know as it was me who did the presentations. 3x A500s with 4meg of RAM running on 50" Rear projection screens. Of course we never ran games

Hellfire project started in 1974 and with production started in 1982. A bit before the Amiga was ever thought of.

Perhaps it was the Hellfire II system.

Care to define "realtime OS" and compare it with AmigaOS? The RoundRobin scheduler alone is not enough to define AmigaOS as "near realtime" as you wrote.

@damocles

My examples perhaps were not the best ones, but...

To my knowledge one of theresons for NASA was that AOS was the best to handle the dataflow from launchpad+shuttle+rocket telemetry and at the same time broadcast it realtime for observers.

Military has used Amigas in many cases. I've faced Amiga being used in anti-tank-missile (TOW2 Amiga in place of the DMGS) practice simulator (I believe lean and mean AOS was chosen because it enabled to handle the I/O from the system & control the videodisc + overlay realtime graphics on top of the scenery + generate authentic battlefield sounds in stereo, etc...)
(this graphics looks the same as I remember from the simulator, did not find user interface photo)


@michalsc

Too time consuming.

In very many cases Amiga has been used because of it's pre-emtively multitasking OSs fast resonse times and fast message passing system. (and that programmer was able to toggle task switching off if needed).

Even in things like multimedia shows it is important to have near realtime system. In the 90's Amiga was the only system to enable multimedia without hickups. Also things like 4...7 synchonously playing multichannel 16Bit sound cards (and multiple audio applications in multitasking, in perfect sync) was only possible with Amiga, because of it's slimline OS.

Hell for that price the radeon driver should be included as well. Only hope the new Cyrus motherboard is going to be a lot cheaper or im never going to be able afford an Amiga again which is a real shame.

The article I read about NASA's use of the A2000 was it's use of running a large status board because of the ease of creating a zorro card (vs ISA card) . No where did it mention anything about the OS. Sure, it was receiving (via the NASA design Zorro card) telemetry feed, but that is what it was showing on the large status board as a client. Anything acting as a mission critical relay in that feed would have to be standards certified hardware.
