AAA! What's happened to my Blizzard1260??

Might a perfect match for the 64Mb chip work on the SCSI Kit?

My *theory* is that most problems related to the
SCSI kit are due to memory conflicts of some kind
(especially problems with overclocking the 1260
and non-working SCSI). I have 2 identical 64 meg
SIMMs to test my theory with as soon as (if) I get
a SCSI kit...I would *guess* that using matched
SIMMs is probably better.

Also, there appears to be a 45mhz oscillator on the
SCSI unit itself, does anybody here know exactly
what that controls? Perhaps changing the frequency
could help the SCSI unit to "sync" better with
an overclocked 1260...? (just taking a wild stab here:)

dont mix 60 and 70ns simms

Maybe that's it. My new chip is 60ns, my old chips are unlabeled. The 16Mb is at least as old as 1997, the 32Mb I don't recall when I got, but 60ns SIMMs are a more recent invention, yes?

There is normally a marking like "-60" or "-6" on the chips on a simm that indicates their speed.  I.i. 70 ns would be "-7" or "-70"

i now have 256mb in my blizzard ppc

cheers

How much is cheap? I have a matched pair of 32M 60ns EDO in my BlizzPPC and haven't been able to find hardlt anywhere that still sells them larger - the ones that did sold 3.3v SIMMS only...

If you got a matched pair of 64Ms 60ns I'd be interested to hear about it :-)

When I bought a Blizzard 1260 card, I also got two 64 MB EDO SIMMs. They work perfectly together. I also own a Blizzard SCSI-kit

Wow, that was a really nice experience!
It really felt like an thiller movie. Reading the first post, suspecting the worst. And then scrolling down things clear up, fortuately!

Ok, more ontopic. I bought two, single sided, SIMMs of 128Mb each a couple of years ago for an absolute bargain. Since I don't have a SCSI controller on my 1260 I only can use one of them. But it sure works great!!

Hmmm... The old chips are 60ns, too. So I guess different speeds isn't the problem. I'll try fiddling around a bit more (maybe by freak coincidence I'm having those power problems when the 32Mb chip happens to be in).

If not, I'd better try to find a matching SIMM...
