Which 68060.library?

[wawrzon]

Well, let me ask what the benefit of this would be. For emulation, the 68060.library is really pointless. For real hardware, it is (still) in supported mode, though probably with longer turn-around times, so I have no problem with it at all when people use it with AROS - or ship it with part of AROS. This is perfectly fine. The only thing I'm asking for is if you sell(!) a CD, please send me a copy, which is - I hope - not asking for too much. (At least, I have now two Amiga Forever DVDs. (-;)

Arguably, it might be anoying that it took so long to actually look into this bug and fix it. In the old days, I had turn-around times of probably one day, now it's more one month. But it also took years to actually discover it... Feature requests and bug reports are still read, though it takes time to implement and verify. Given that I hear nothing, the interest must be really low, or things must really work well. I don't know which of the two is true,  probably more the former than the latter.  

So I guess, it really boils down to one question, and that is: What would be better under a different model, and what would it enable?

what concerns different model, i see aros as a sort of code preservation repository, where all the good parts can be stored and eventually maintained beyond the point, where they would have been discontinued by their creators otherwise. that doesnt mean that anyone can be forced to contribute, but i dont believe anything worthwhile can be done on widest understood amiga platform today by a single person, let alone anything commercial can be pulled. sure, im certain you can maintain what you have developed for another few years. i dont ask you to contribute your code to aros. aros has already 680x0.library that includes 68060.library implementation. all i could imagine to ask to review the code if need be and consult the developers not to let them run into the bugs you are aware of.

@THOR: Are you able to create a special 060-LIB for 68LC060-CPUs.
Eyetech released a Winner(Apollo)1260 @ 75 MHz with a special "LC"-Library.
OK, it seems to be useless for "MMU"-Libs, but it could be nice to have a alternative choice.
Sideeffect, on A1k.org some guys are working on 040/060-adapters with higher clockrates.
(Warpengine 4040 -> 4060@80MHz .. thinking about MC68060FE133 and quad-clock setting)

Do you mean "LC" or "EC"? As far as the MMU goes, it is actually not required, not even for the mmu.library, so the 68060 without MMU should work out of the box, no strings attached. The mmu.library of course then doesn't do anything useful except sitting there and saying "hey, here's no MMU, pass on", but the 68060 lib should continue to work.

The LC does not have a FPU. I'm not sure I'm currently supporting this, but you might try. If it does not work, it wouldn't be a major trouble just to disable the FPU enable code because right off my head I don't remember what I did if the FPU is absent. Best would be just to try and let me know how it goes. It shouldn't be a major trouble to get this into the main branch - a special version wouldn't be required.

[guest11527]

Just quickly reviewed what I had, and it seems to me that the code tests correctly whether a FPU is available or not, and only installs the FPU related patches if it finds a FPU. Thus, at this moment I don't see any reason why it should not work on a LC or EC processor. That being said, I haven't tested it lacking the hardware, but you probably can just give it a spin.

What kind of CPU are you working with  .. on your broken A2000?
I think Mozart could help you to pimp a 040-system to 060 ...
He is going to test the MMU-Libs on his system (C=3640 with 68LC060).

"Working" is a nice word. I'm not so much working on this machine anymore for apparent reasons.. The CPU is a first generation first mask "broken as designed" 68060 with MMU and FPU. I forgot the mask revision, but it has all the bugs a 060 can have. But that's actually not the broken part about it. I have a 2060 that is currently installed, a GVP040 and a GVP030 card, just in case I need to do something on the other code branches.

There are a couple of things I know that are broken (disk drives, CDRW, and add now the RTC to the list), but there is something else I'm not clear about. If I leave the machine off for months (which is not so untypical anymore), then it refuses to boot. The usual procedure is then to open it, rip everything appart, put everything back in and - voila - it's alive. Hard to say what's causing this. Weary electronics I say. It's just old crap.

BTW, could you do me a favour? Please go over to a1k and send greetings to Mozart, and let him know that it doesn't take a MMU to install the mmu.library. I know this sounds weird, but it's true nevertheless. In his configuration, the lib doesn't do much except sitting in the corner wining, but it will nevertheless do enough to load the 68060 support on an EC (and telling the rest of the system that there is *really* no MMU it could program).

Greetings, Thomas

I thought my machine had the same problem on my A1200T/060.

But then I learned a trick.

When pressing the power button in if I keep holding the button down for 2 seconds, instead of quickly releasing it like a normal person does, then the machine almost always boots up correctly the first time.

My A3000 and A1200T both have a pushbutton type of power switch, unlike my A2000 which has an actual power switch.

It's an A2000, so it actually does have a real switch. The problem is not that the board doesn't get power. The LED is lit, but only "half". If the machine is in bad mood, it just keeps sitting like that doing nothing. Fan is rotating, but nothing else.

It's dead, Jim.

bad caps and/or bad psu?

@ThoR

bad caps and/or bad psu?

All possible and all not too unlikely. But no matter how you put it, I'm not wasting more money on this trash than I already did. The A2000 gave me a lot of trouble over the years, and no matter what I do, it will continue to give me trouble.  That said, the caps look optically fine, but given their age, it is indeed not too unlikely that they have dried out. Disk drivers are likely only dirty, but I don't mind anymore cleaning and oiling them.

[Oldsmobile_Mike]

I'm going to throw in a vote here for ThoR's library, also.  Even though I only use his stuff with a 68040, it works brilliant!

I don't think the MC68060FE133 even exists or has someone found some secret military inventory ?

Of course 68060FE133 exists.  Duh.
I donno if there is an MC on the front or not.

But it doesn't matter.  The point is they exist and they work.

They have the MC but they are "EC" and SMD only. Here is a close up pick from the Natami site:

The price may go up soon if they are using a fault tolerant pair of them on the Tomahawk cruise missiles :/.

Speculation is they are remarked 68060FE75, Freescale have never heard about it. The mask dates back to 1997.

Freescale have heard about them so please don't say that they haven't.

In all my years of working with amigas i've never seen an a2000 with "bad caps" mainly thats a600/1200 afaik..

and why do you still have a Satanic avatar? Its against the TOS and is offensive.
