Which 68k Mac? The 030 ones use the DayStar Turbo 601. Most Quadras use the DayStar Power Pro. LC or "pizzabox" 040 Performa, Centris and Quadra boxes will need the DayStar Power Card. The Power Card came in a couple of versions and plugs into the 040 CPU socket. The 040 then plugs on top of the Power Card. The main problem with the Power Card is it blocks the LC PDS so you can be all hot with the 601 but can't have a video or ethernet card inside. I've seen a website where someone did a hack by obtaining a pair of new LC PDS connectors then stacked them to raise the connector above the Power Card. The whole works was then stuffed into a desktop PC case. :) For 601 upgraded 030 Macs, you need to use the DayStar control panel. Installing System 7.5, which is the minimum the DayStar PPC upgrades will run with, then updating to 7.5.3 somehow changes the gestalt ID to make it call itself (at least the IIci) a "PowerMac 475"! Then OS 8.0 and the 8.1 upgrade install with no trouble at all. The "PowerMac 475" would be the LC or Performa 475 with a Power Card. Apple sold their own versions of the Power Pro and Power Card, so Apple's control panel or DayStar's work. With the Turbo 601 in an 030 Mac, Apple's control will only turn the 601 off, not on. As for enablers with a DayStar or Apple 601 upgrade... 7.5.x requires an enabler on the PPC Disk Tools floppy and in the System Folder of the hard drive. Do a clean FAT install, then drop the enabler in the System Folder. 7.6.x requires an enabler only on the PPC Disk Tools floppy. To ensure proper support, do a clean FAT install on the Mac with the upgrade installed and activated using the control panel on the 68k Disk Tools floppy. The Mac will restart then refuse to boot from the 68k floppy, so pop in the PPC floppy with the enabler in the System Folder. 8.0/8.1 requires no enabler at all for the 601 upgrade. Zapping the PRAM turns the 601 upgrade off, so on an 030 running 8.1 you'll need a 7.5 to 7.6.1 68k disk with the enabler and the control panel (just will fit!) to turn the 601 back on. > Is there a list of cards and drivers that work with > a PPC based system? No super comprehensive list yet. The main troubles are with video cards. Many NuBus video cards will work with a PPC, but none of their acceleration features work. There are several video cards that have "issues" or flat out don't work with Systems higher than 7.5.2 or 7.5.3. The 24AC works fully in 68k and PPC, but with ROM 1.0 it will not work with anything higher than System 7.5.2. ROM 1.1 fixed that. ROM 1.0 24AC cards were only sold by Radius, others were initial versions sent to Apple Developers. Later Apple and Radius sold the 24AC with ROM 1.1. There's no upgrade or fix, so don't buy a 1.0 24AC unless you never intend to use it with any System newer than 7.5.2. The Apple 24*GC in a 68k is limited because its acceleration drivers don't like Systems newer than 7.1. However when used in a PPC there is an ATi extention that enables the acceleration on later Mac OS versions. It should work in a 68k with a PPC upgrade. See the pickle's Mac FAQ for more info.
