I have a Daystar 68040/40 card that I am installing in my SE30. They daystar site lists three different downloads for their 040 cards. Turbo040 software, Quadcontrol software and PowerCenter software. This card also has, I believe, 128k of backside cache on the actual card, not as a add-on daughter card. The processor has a heat sink mounted on it. Is this a PowerCache, Turbo040 or (?) card? Which version of the software should be installed? This is going in a SE/30 w/32 mg RAM, 230 mg HDD running OS 7.5.5 with Mode32 7.5 installed. It will effectively be a SE/30 EC, per Gamba's site, with a MacCon Ethernet card, IIsi Daystar PDS adapter w/120 pin right angle connector with this cad installed. Thanks.
I have not installed a Turbo040 in an SE/30 (only the IIci) but it seems to me that you want the latest version of the QuadControl CP that you can find. I think that is QuadControl 2.3.
You probably have a Turbo040. There was another line of upgrades from Daystar called the Universal PowerCache. These used a 68030 processor. That's a different set of upgrades.
There were two main revisions of the Turbo040. The earlier versions were built out of a bunch of programmable logic device chips (bunch of square chips with 'J' leads). This version has a removable 128K cache daughterboard on the back--or lacks the cache but has a connector at the top back of the card for the cache. The later version, which it sounds like you have, was the "ASIC" version. It has the 128K cache soldered down to the main board, has no daughter board and no connector on the back for a daughterboard.
There was a recently completed auction for a pair of the ASIC version here: <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2762078238&ssPageName=ADME:B:BN:US:1> The two distinguishing features of the ASIC version are the lack of the connector for the cache daughter board on the back, adn the presence of a large square chip in the middle front of the board, in addition to the 68040 CPU.
I have several of the 25 MHz Turbo040 in the earlier version and found that they upgrade to 40 MHz just fine, by removing the oscillator and replacing with one that runs it at 40 MHz. Of course, since yours already runs at 40 MHz that doesn't really matter in this case.
