hardware OS4   hardware OS4 : ACK CPU Module Design Rationale
   posted by ssolie on 21-Jul-2006 14:44:16 (9144 reads)
ACK Software Controls has continued beavering away at their projects while Amiga fanatics continue the agonizing wait. If you have any questions or concerns, come join us in the #amigaworld channel for an IRC chat with the designer himself. Unless of course you enjoy wasting your days in web forums with yet more people that don't know any more than you do.



With that in mind, we have the following snippet of info. regarding the CPU module design rationale from a recent forum posting to wet your whistle. This is the kind of stuff that is discussed live in the #amigaworld IRC channel:
Quote:

Here is just a quick couple of notes (in no particular order):

1) Website will be up and running when products are available for retail.
2) The PowerMac Meg-Array connector pin-out is propietary and not readily available, believe me I have tried that route.
3) AmigaOne owners need CPUs and the general desire from most people I communicated with want upgradeability.
4) The other aspect of the CPU module is from a financial perspective. Putting the CPU on the motherboard adds significant upfront costs to a motherboard run. I can inventory a much larger run of motherboards without CPUs and build CPUs as necessary.
5) It wasn't that difficult to get the PV TL working with the common CPU module. That issue has been resolved. Original AmigaOne CPU modules will work with the PV TL at 133MHz FSB and the 7448 CPU modules will work @ 200MHz FSB. Please note that the main intent was that people who invest in the 7448 modules have an upgrade path. Similarly, it allows for people to move up from the AmigaOne boards at a lower cost to the end consumer.

This is extremely interesting and very promising, but does this mean that PowerVixxen TL will have a new type of CPU-board connector on the motherboard, rather than the used MegArray? What is the plan for this? Yes, soldering it on the motherboard is not a wise idea. We all agree on that

Maybe it means there's going to be a live demonstration on IRC.

No, that only means these boards are not compatible with the ones used in the PowerMac (as we already know, the A1 modules won't work in the PowerMac) and vice versa.

ACK says the CPU module will work on oth AmigaOne and PVTL. AmigaOne has Megarray connector. Thus, how can PVTL have different connector?

He mentioned the Mac Megarray conenctor was not an option. It's actually the same connecto, but he pin connections are different. You can physically fit a Mac CPU module into AmigaOne, but it won't work. You can physically fit an AmigaOne module into a Mac, but it won't work.

Okay, now i understand It will be the usual MegArray 300 CPU-board connector, but the pins will be different only to be compatible with the current A1 CPU-cards, and not the ones from PowerMac The MegArray 300 CPU-board connector itself is excellent

I'm glad that PowerVixxen TL will use it too

Any way to make an adapter or rewire the thing?

How different are they?

Can there be a hardware hack to make it work?


P.S. I'm not going to try this on my A1, Just wondering if it could be done!

If it can be done, then perhaps this might be a good way to get an Amiga One. Buy a PV without CPU, Buy a used PPC Mac cheap and hack the CPU card for use in the PV.

@nzv58l

As Adam said, the PowerMac Meg-Array connector pin-out is proprietary, which means you more or less need to buy Apple to get your hands on it, and thus no one outside Apple knows how different they are...

Some one point me to some docs (if they exist) or tell me a hack is
possible and I'm on it. The more hardware we can get in the game, the better.

Talking on IRC with Western hemisphere people may seem like fun, but they don't seem to do much during the "normal" hours of the day. They seem to wait until I'm asleep, then have all the fun.

"thus no one outside Apple knows how different they are..."

What about the 3rd party CPU upgrade manufacturers - the
meg-array Apple uses may be proprietary, but it's hardly
unknown or hard to backward engineer. They (3rd party
CPU upgrades) start at slightly under $160 for "sawtooth"
(meg-array) macs. I've got one of these G4 CPU upgrades
in the G4 mac I'm typing this on.

These people seem to have a clue. In particular, look at the solder pads at the bottom of the picture here. Yes, that's a megarray on the other (not visible) side of the board.

The name on this card leads me to believe that it also uses megarray.

(Of course, someone would have to get the Apple info from them, or get the A1 info to them. Good luck.)

OTOH, having -two- boards (adapter and cpu) floating above the Articia on my A1 sounds like a bad idea.

Note to those who can't bother to click on the links: It's Sonnet Technologies' Encore line.

EDIT: @Maczilla - boy, I really should read an entire thread before I post.

Ah good, more info about ACK's products!
My A1200 is waiting quietly in its box, soon baby, soon....

Wizz.

Yawn, it seems ACK is back to teasing us - except for those with the time & inclination to use IRC. I wish he'd just make up his mind, and either officially tell us his current progress, or just shut up. Leaking info in dribs & drabs is not the way to be taken seriously.

Either way, since he's back to working on his hardware, it seems just childish (or down-right suspicious if you're cynically minded) to still not post any pics...

Excuse me for being dense, but with all the comings and goings I don't really understand what products are coming out. Please correct me if I'm wrong, but there will be:

1. A CPU card for AmigaOnes
2. A PPC CPU card for A1200
3. A PPC CPU card for A4000
4. A standalone machine

For those of us with no AmigaOnes and broken A1200s option 4 is the best step. And indeed, from what Hyperion say, the only way OS4 will be released is with available and non-classic hardware. So this standalone computer is the most important for everyone.

Good to hear that ACK is continuing development. I will be very interested in purchasing one of these boards when they are finished.

So good to see them ignore the handful of negative comments and continue their work.

@ChrisH
It wasnt ACK who posted this news item. Adam just posted that snippet of information in a thread that were becoming a bit to speculative. That Ssolie decided to make it a news item is just a service for the ones not reading all the forums. You would find that if you had a well founded question for Adam you would probably get it answered by meeting him on his terms. That is IRC or just by mailing him directly. Ive done both and got quick and concise answers from Adam.
I know we all would like pictures but think of the consequences. Remember when Troika published pictures. Each time the pictures were analyzed by everyone and in the end they were all called a hoax by at least one person (Whether they are or not is not an issue in this thread however)
