Would you like to share with the rest of the class?

It looks like a BPPC card with some sort of custom heatsink?? Fess up man! what is it?! :biglaugh:
-
Looks like an A1200 card with a thumb hole in it to push the card on to the mobo connector. :drink:
-
it seems some help is need. part in the middle is old.
one of these processor has a future the others does not.
watch out for anything thats patent pending.

I'd guess we're not the only ones needing help here.

I'm guessing from that picture that you've made a board that adapts a PPC chip to fit on a BlizzardPPC board.
But honestly the first picture you posted is just a photo of a BPPC with a custom heatsink.
If you want us to have a *clue* what you're on about you could just explain it in simple english!

He has never managed to do that.
His posts always give me a massive headache

do not post any comments under this link. the processor speed has not been set yet. ram is now 256Mb (modifyed ram module)

what makes you think i did not do it,if so tell me who did it then?
i think the second upload says it all.

Your posts in this very thread perhaps? :)

like what i wont tell you what it is,i was just messing around so this is what it is.
it's a BGA socket for the CPU.
so if the CPU go's faulty,no problem just undo the four screws change the CPU under 1 min.
blizzard ppc card is classed as unknow for now,as the CPU as not being set this is due to BVSEL as being added in and has not being tested yet,but has pass test upto 300Mhz but with a little bit of luck should work above 300Mhz.

He wasn't saying you hadn't done *something* he was replying to the comment that said you've never managed to make sense in a thread about your projects.

Ah now that makes much more sense.
Which set of pins did you add the socket too? The outer ring QFP or the BGA? How are you clocking it that high and what effect does it have on the rest of the board?

it's a BGA drop in replacement.
effects: none when running OS4.0 100% perfect
problems: some of the cooling system is missing/not ready can't run for a very long time.
warp-up under OS3.9 has a problem drop back to 74.666Mhz (298Mhz) with 68 or 68.666Mhz for 68k processor (10PPM).
important: must have the right ram modules i found most will fail even if it marked 50ns,i did two modification to get it to work.

OOPS
iv found the problem its now gone from a dream to something that is now real im posting here with the new speed.(BETA)

Why not just use this?

Assuming you don't give a fig about the stability of 3.9, what's the fastest stable clock speed you could get? 400mhz? 433?

OS3.9 was never the problem **it's warp-up games only**.
but now that the problem has been fix,i will retest.
it does not matter what the final speed is,i just want to see a improvment.
but first i wiil finish my motherboard modification pcmcia LED. it now has card detect,this now shows me proper insert of the pcmcia card,this does not mean the card is compatible,i have to wait until the LED change colour from red to green? i say green as 1 card shows yellow when inserted.
in other words this A1200 motherboard can detect if the PCMCIA cards are compatible with A1200 motherboard regardless if drivers has been loaded or not.(BETA).
NOTE: i can not test every card but all cards here that shows green or yellow works. any card that shows red is already known not to work.

@delshay
I'm really interested how you managed to solder the socket to the card?
also what type of modifications did you do for the ram modules?
adding a waitstate on the card? or something on the ram module?
-
UPDATE:
with the fix warp-up games is err kind of working again got lock-ups about say anything between 20 and 30 mins.
but this was done under OS3.5 with the 68k set at a new speed 69.666Mhz with the PPC processor unchanged.
but there are a few things i can do to try and dial this out but the whole project remains BETA but the speed should be 70Mhz for 68k and 320Mhz(80Mhz osc) for PPC. if it passes all test then everything moves to stage two.

How are you doing that? Nice mod!!
