DayStar Turbo601 for IIci?

[Lee Adamson]

I may have a line on a Turbo601.  The seller isn't sure what model it's for, and I am not turning up much on the web about how to determine whether or not it will work in my IIci.

Do any of you have any advice?

Thanks, folks.  I really appreciate it.

Yeah, that should work. What terms are you Googling? "Daystar Turbo601" or even just "Turbo601" gives me several pages describing what Macs it works with.

I was under the impression that there were different models, for different models of Mac.  Was there only one?

There are supposed to be different versions and the one I have got came out of a IIvx where it was working just fine.

That same card works just as well in my IIci and IIsi. Not sure what the actual difference between the different versions really is.

There are ones for 040 pds and ones for 030 pds such as in the iici or iivx. I have one it my iici, it’s pretty neat. It even changes the startup sound to PowerPC. The 040 card will fit in more machines but in my opinion the 030 card is worth more do to it being more rare.

Well, the price was pretty good so I went ahead and bought it.  I'm pretty sure it's for the 030 PDS, but I guess if it doesn't work in my IIci I can figure out which Mac II it's actually for and try to resell it at a little bit of a loss.

Thanks guys.

So now I am going deeper down this interesting rabbit hole....

Does the cache still work when you have the machine in 68030 mode via the control panel, or will it run dog slow like a IIci without a cache card installed?  I assume I'll have to switch back to 030 mode to run AU/X.

Are there any socket-level type upgrades that could potentially replace the 601 with a 604 (I think they are bus-compatible, anyway)?  I mean it would be kinda silly in a way to run even the 603 at such a low clock speed, but the increased pipelining and such might still give a significant performance improvement, perhaps even 2x.

The 040 cards were called the PowerPro, not Turbo. Apple also rebranded those as the Apple Power Macintosh Upgrade Card, though they only sold the variant that ran at a maximum of 66MHz. It was clock dubbled from whatever the 040 ran at, so only in machines like the Q800 would it run at the full speed. Which is why I moved mine from a Q700 to a Q800, besides the fact the 700's not currently working.

The 601 is a QFP type IC. I'm not sure if any of the later QFP PowerPCs are pin compatible, but replacing one of those would be pretty dang difficult.

Easy way to tell before you get it, the '040 PDS PowerPro will have a much thinner black connecter while the '030 PDS is a thicker connector and (at least on the ones I've seen) white in color.

That's the more common 040 PDS connector PPC upgrade.
