Will there be an ACA1240 or ACA1260?

[Blinx123]

Can u name a single piece of software that makes such an assumption?

I have never met a program that did such a thing.

I don't think anyone assumed that except you.

Tons of ppl used LC and EC parts and I never heard of them not working.

Supposedly, Quake will not work without a fully functional FPU. Can anyone confirm this?

[Blinx123]

The first five revisions are far from rare, are they?

Talked to a distributor today and they still had eighty 50MHz CPUs with MMU and FPU in stock.

Guy warned me not to use these without dedicated cooling though. At least not when I'm overclocking them to 66MHz.

I was also looking around for inexpensive 128MB sticks, but couldn't get a definite answer on whether 60ns RAM (of which I should still have a few sticks) is good enough for serious OC (as in an 80MHz 060).

As nice as 50ns sticks would be, they're kind of out of my budget.

First five revisions of what? the 68060? There are only 4 masks of the 060 from what I can tell.
I'm not sure if having the latest greatest revision is all that big of a deal either. From all of the 68060 turbo cards I have seen and all of the photos I can find online there seem to be a fair amount of them with the "buggy" revisions.

Here is the errata sheet if you actually want to check for yourself:

Ok.

Thanks.

I assumed there were six revisions since the last one commonly goes by "68060 Rev6"

I am curious, is it the limitation of the actual 68k that it cannot continue to 68070, 68080 and so on and that it cannot go beyond 50 Mhz like 230 Mhz or 1 Ghz or is it the limitation of the Amiga classic itself that forces the maximum limit of 50 Mhz for all 68K except with forced over clocking?

You could probably clock a 68060 to 230MHz or 1GHz, but then it really wouldn't be a 68060 anymore.

A shrink alone is certainly not enough. You would have to redesign vast parts of the pipeline.
In the end, it would turn out to be somewhat like an Intel Core 2 Duo (Pentium 3).

As for not continuing to 68070/68080/etc. Blame Motorola for going PPC.

Lastly. It's probably worth mentioning that a 68060 isn't just a souped up 68000 (your first sentence seems to insinuate that).

Chimming in to say that I've just been offered a Blizzard 1260 (well. Blizzard 1240 modified by Stacho, actually. But that shouldn't make a difference, aye?) with a Rev 6 68060@77MHz.

Waiting for some pics now, then I'll decide whether to buy it or not.
But looking good, so far.

[Blinx123]

That would  do nicely.

It sure would.

I mean, it costs quite a bit more than all the other accelerators I've been offered before. But then I realize that labour isn't free either and it would probably cost me quite a penny to let someone rework a 1240, as well.

I hope I can easily remove the coolers though.
The seller placed two on there (one on top of the CPU and one below it) and I'm quite positive that I won't be able to keep it that way without towerizing my Amiga 1200.

Which reminds me of another fun project.
Modifying a standard ATX tower, so it will suit a Amiga 1200 plus busboard, accellerator and RTG.

Has anyone done something like that before?

[Blinx123]

I'd be interested in why they added the coolers.

"They" didn't.

The seller did it by himself.
As he explained it to me, he's kind of a cooling junkie and very fond of his Rev 6 060, so back then he didn't want to risk screwing up his CPU.

I asked him to do some tests on it and post a video. He doesn't have Quake and while he was more than willing to find some wads, I told him that there was no need and that ScummVM (Sam&Max) would be plenty enough.

Always wanted to play Sam&Max on an Amiga. This will be interesting.
Probably still not enough horsepower for another personal alltime favourite of mine, The Feeble Files.

Pics and video are in:

What really got me though, is the fact that he said something to the extent of the CPU not being a Rev 6, after all. Apparently, while the markings on the CPU point to Rev 6, it's recognized as a Rev 5.

EDIT: There were some other pictures of the trapdoor, but that stuff is like the SAW V of Amigas. Don't think I would want to do that to my trapdoor (drilling a large hole into it).

I wonder if I should just slightly rise my machine (by adding some large metal feet to it) and tuck away the trapdoor. Surely, the amount of dust can't be that tremendous.

[Blinx123]

Sounds like the ticket.
BTW - That cooler on the '060 looks a little small (and no fan).
If possible, I'd replace it.

If I end up buying it (still have to think about it, since it's only a Rev 5 and a bit more expensive than the Rev 6 carts with 64MB 50ns EDO Stachu used to sell), I'll probably just switch the coolers.

I don't really see the sense of having an inward facing fan, while the CPU itself basically starves from the lack of aforementioned fan.

BTW: Is there any way telling whether a CPU has been socketed or not? For an Amiga newbie like me, it's always hard to tell from the photos and I almost always forget asking the seller.


EDIT: WhichAmiga reports a Rev 5, indeed.
Is there any known issue with WhichAmiga and Rev6 CPUs or is it really a Rev 5 then?

[Blinx123]

I have decided to take this guy up on his offer.

However, I'm still in contact with three other sellers. So if anyone is looking for an Apollo/Blizzard, PM me.

On another note: I've just received an offer for a Mikronic Z3i for 150 euros + shipping.
Might this be a worthwhile future update?

EDIT: Ok. It cost me quite a lot of money, but I'm 80% there.
After waiting 12 years for my Amiga (about the same amount of time people in the USSR waited for their cars. Lol), it took me less than a month and approximately 700 euros to source nearly all the components I ever wanted to have.

Bought 2*128MB 50ns Superslim EDO (the last the Ebay seller had in stock) today (they cost me about the same as my 16GB high-end DDR3. Ouch), already sourced a Z3i for a possible future upgrade to Cyberstorm(PPC) or UltraPPC (if that ever comes out and supports Amiga 1200 busboards) and am about to drop some money on Amiga OS 3.9.

Am I one lucky son of a bitch or is it money that plays a huge part here? Personally, I'd have imagined it to cost about two to three times as much as it ended up costing me. Going by what someone on here said, the Micronik alone should've cost me quite a dime.

The only thing that is now left finding out is whether I can install a Micronik Z3i and a Mediator at the same time or not.
This and I'll need some documents on how to successfully mod an ATX midi/big tower, since I really don't want to spend money on something as generic as the Amiga specific towers.
