Hi All,

Long shot, but does anyone out there have manuals, schematics, PAL dumps, or any doco around the Daystar 33/030 Accelerator II?
Searching the web I've found very little info - even Daystar's Internet Archive pages are sparse. A couple of ads and tests in MacWorld March '89 are about all I've found.

I managed to get very lucky and find one in a Mac II I picked up to restore.
After initial problems the card is up and going now - but worried something will die and no resources to fall back upon.

33MHz 68030 and a 68882 in a Mac II you say.... :geek:

It is very similar to the PowerCard 030 (IIx variant, 50MHz), but its shape differs slightly.
I asked questions about this card on "the other forum" before finally managing to identify it myself.

I have a Daystar manual that seems to cover several models, but it will take me a little while to find it again.
That said, it doesn't answer all your questions.

Oh wow - a scan of a manual hold be awesome if it's got any Accelerator II info.

Searching for PowerCache I did find these...
