Amiga Workbench was not the first multitasking OS

Some guy posted an old video of the Apple Lisa and the OS used, in early 1984.

You'll see multiple apps running at once.

Nice historic vid.

That was a $10,000 system at the time though, but it does have some nice first features like mouse driven GUI for such an old machine.

Its multitasking was co-operative, not pre-emtive like the Amiga, but again the idea is there and probably a first.

A machine that moved the whole computer scene forward in a big way.

Fred: Of course it wasn't? I'm pretty sure before that, the Xerox Palo Alto had multitasking. And before that, probably some dodgy IBM mainframe had something like multitasking serving multiple terminals and print jobs. (But no WIMP though. The Alto was first with that.)

I will agree that the Amiga was not the first computer with multi-tasking. The Multics MainFrame operating system was the first. The GUI Apple Lisa a flop, it had a price tag of around $10,000 dolars and Apple did not know how to promote it. But the Amiga 1000 was the first home computer to come standard with a multi-tasking GUI environment for under $1500. Still one of the best, to me a least.

@Photon : I think Fred is trying to disspell a myth that you'd be surprised how many people believe! I used to believe it was the first pre-emptive multitasking OS, but the internet and magazines soon fixed that gap in my knowledge

@P-J

But, MacOS/System didn't have pre-emptive multitasking until the late 90s (MacOS 9 was realeased when, 1999?). So, he's just dispelling the myth with another myth.

Well then, I sit corrected. Pre-emptive multitasking was my topic of conversation. If this Apple Lisa doesn't have it then the myth is not disspelled.

I am not sayng the Lisa was first, only that the Amiga was not. Though Amiga scored first in the pre-emptive arena. I believe the OS Xerox used was called SmallTalk.

The Amiga was the first HOME COMPUTER with pre-emptive multitasking.. Multitasking was already invented in big iron OSes decades before the Amiga.

I did a little digging, and here's the results. MicroWare OS/9 Level 1 was the first pre-emptive multi-tasking UNIX like OS for a home computer, the Tandy Color Computer 2. It was released in 1983! It did not have a GUI interface though, but that came latter and it was called DeskMate, and you could run OS/9 in less than 64K. The cost was around $50

P-J, bet ya didn't know that MicroWare OS/9 was also ported to the Amiga also...

I'm afraid so, the first Apple OS to have pre-emptive multitasking was OS X.

There were at least four programming languages for the Xerox Alto, Smalltalk was a verbose-ish object-oriented language.

The Alto was about as multi-tasking as the first Mac: It could do certain things like talk to I/O and screen while running code (due to its hardware), and you could have more than one app open, but when you switched apps, the former app would stop executing.

True multi-tasking is in book defined as being able to run several apps at one time; preferably as many as the memory can allow for. Two would do it for me - that's "multi" all right. It would also have to do that on a single processor - having one CPU for each task is just a matter of hardware configuration. To be a multi-tasking _OS_ also requires an environment the tasks use to let the user operate the computer.

The Alto was a revolution because it had these things:
1. WIMP (Windows, Icons, Mouse and Pointer)
2. Object-oriented programming (AND os!)
3. WYSIWYG (portrait screen, hires bitmap)
4. Networking (yes, Ethernet!)

It was never a personal computer though, since it wasn't commercially available - no person could buy it, only institutions. (I remember researching the First Personal Computer and coming up with a Very early French computer, but I can't remember its name right now... bah.)


I know IBM mainframes served dozens of users running their programs concurrently, before the Alto. But I don't know if more than one program was run on one CPU - what those mainframes looked like inside is unknown to me. And it probably wasn't an OS per se; probably just a main program switching time slots between more than one user.

Some site lists UNIX as the first multi-tasking OS - in 1969. Wouldn't surprise me.

Pre-emptive multitasking OS's on the big boxes have been around for a very long time, and were sometimes also referred to as "time sharing" systems. The first programming job I ever had (in 1976) was on a proprietary OS that the company I worked for developed, and it did pre-emptive multitasking. Basically all pre-emptive multitasking OS's use a time-slicing model, with individual users yielding the remainder of their slices at any time that they need to wait on a system resource, such as an I/O to be completed.

The Amiga was the first home computer with pre-emptive multitasking though. The Lisa and the early Mac would allow you to have several tasks going at the same time, but only one could be active at the same time, and the OS wasn't capable of automagically switching back and forth between them. The Amiga's OS has much in common with Unix, and I'd be very surprised if Unix didn't influence the Amiga OS design, with the goal being to provide the best Unix features with a smaller set of hardware requirements. They succeeded brilliantly at that, IMHO.
