@Chuckt

Yeah, I read that last year, been hoping for some cheap 68020 for a Minimig revisited :)

Yeah, good news. I also learnt that they use these CPUs in the Eurofighter Typhoon! It's part of the radar and flight systems

So the PA-6T is in the Lightning II Joint Strike Fighter and now I learn there is 68k in the Typhoon! Great to see Amiga tech in high tech products!

It would be neat if they offered upgraded cpus (for example higher clock speeds).

I expect the target market will be low volume Military and Industrial applications where high prices can be charged as the equipment must be kept going. There's no market for mass production so there's unlikely to be any bargain priced new 68020s manufactured.

For a Minimig revisited why would you go with a hard CPU when the softcores like TG68k are getting so good?

Ah, good news for those looking for replacement CPU's for their Commodore SuperPETs, CoCo's, and others.

Neither the 68020 nor the PA6T are "Amiga tech". These are processors that get used in Amigas (A1200) or a very rare and EOL computer labeled AmigaONE.

Maybe not Amiga tech but why use 68K not x86 something tells me 68k is more reliable don't wont your euro fighter falling out the sky due to cpu error lol

Most people don't know the chips were developed for the space program and specifically to be able to function under radiation from space. The government sold the technology to the private sector.

Will signals still go through regular chips if they are exposed to radiation and what do you want to depend on in harsher environments like war?

Not all Mil spec chips are designed for the Space program.
And the chips this company produces are not all Mil spec chips.

I bought all of the magazines back before Amiga was introduced. I remember. Even some Mac users were aware of it.

Put your router next to the microwave in your house and turn your microwave on. It usually knocks out our WIFI temporarily. A chip has to stand up to magnetic radiation in order for it to continue working in combat.

If you read the article it says:

"He said the Freescale 68020 processor is available now, with the full military version of the 68020 in production by the first quarter of 2015."

We might not get that version and rightfully so but you can't be flying in a plane that is subject to interference because that is counter productive.

The co-investment between defense and civilian space was very real and hugely important," said Hubbard.

"With Apollo, they needed to cut down on weight and power consumption. Mass into space equals money," he said. "It has been and continues to be about $10,000 a pound to get to lower Earth orbit. They certainly don't want computers that take up basketball courts. They want something very powerful and very light that doesn't take massive power. That was one of the driving requirements that led to the development of the integrated circuit, where you put all the components on a chip rather than having a board stuffed with individual transistors and other circuit components."

He added that the microchip took the high-tech industry to a place of mass production and economies of scale.

"There was a major shift in electronics and computing and at least half credit goes to Apollo," said Hubbard. "Without it, you wouldn't have a laptop. You'd still have things like the Univac."

@Chuckt

I can buy the argument that Apollo helped drive development.
Nut there were no microprocessors used in the NASA Apollo ptogram.
While ICs may have been used, full cpus had not be created yet.

I'm just not sure what role the 68K played at NASA.
Amigas were obviously used by NASA.
And I know there were 6809s used in the fueling system for the Space Shuttle.

But I have no info on specific use of 68K processor by NASA.

Obviously, the Mil spec 68Ks have multiple uses outside the space program (after all, military hardware must be radiation and heat resistant too).

@iggy

The 68000 was on the Space Shuttle because they had a radiation hardened version:

The 68000 line of processors has been used in a variety of systems, from modern high-end Texas Instruments calculators (the TI-89, TI-92, and Voyage 200 lines) to all of the members of the Palm Pilot series that run Palm OS 1.x to 4.x (OS 5.x is ARM-based), and even radiation hardened versions in the critical control systems of the Space Shuttle. However, they became most well known as the processors powering desktop computers such as the Apple Macintosh, the Commodore Amiga, the Sinclair QL, the Atari ST, and several others.

https://en.wikipedia.org/wiki/Motorola_68000_series

Built by Honeywell Aerospace, each MEC originally comprised two redundant Honeywell HDC-601 computers,[12] later upgraded to a system composed of two doubly redundant Motorola 68000 (M68000) processors (for a total of 4 M68000s per controller).[13]

https://en.wikipedia.org/wiki/Space_Shuttle_main_engine


[132] ....the early 1980s, Marshall Space Flight Center began studying a Block II controller design because it was becoming impossible to find parts and programmers for the late 1960s components of the Block I183. The revised computer uses a Motorola 68000 32-bit microprocessor. When selected, it was clearly the state of the art. Instead of plated wire, a CMOS-type semiconductor random-access memory is used. Finally, the software is written in the high-level programming language, C. Such a computer reflects the current design and components of a ground-based, powerful digital control system. The C language is also known as an excellent tool for software systems development. In fact, the UNIX operating system is coded in it.

That's not because the chip isradiated but because the microwave own uses the same frequency as WiFi, but the owen is a couple of thousand times more powerful (though most of that should be contained).

Space radiation also consists of high energy/velocity particles that can knock out a transistor if its hit dead on, of give a blink in the eye if the retina is hit. No normal radiation on earth does that.

According to this list no 68000 was used on the space shuttle.

Here is some information about the Space shuttles main computer:
https://en.wikipedia.org/wiki/IBM_AP-101
http://history.nasa.gov/computers/Ch4-3.html

It used a predecessor of the PowerPC

We also use the 680XX in several US military weapons systems I work on. I know its also in several embedded systems as well still in use today, including some other military applications. Its still a very reliable processor and does its job very well.

This is blowing my mind.
Are y'all telling me the military is NOT using 48bit microprocessors with 40bit self-encrypting ECC RAM? And there is no Amiga OS controlling the radar systems?

Now the obvious question is: Can I run AmigaOS 4.1 FE on the JSF?

It definitely is running OS4. That's why it's cannon doesn't work yet since that feature is still on beta and will be out in two more weeks (2019)!
