The 601 upgrades for 68k Macs require a minimum of System 7.5. Apple's 601 upgrade control panel is designed only for 040 Macs. If you use it on an 030 with 601 upgrade it will only turn the 601 off! You have to use DayStar's control panel to turn the 601 on in an 030 Mac. System 7.5.x requires the 601 enabler on the hard drive and the PPC Disk Tools floppy to boot. Mac OS 7.6.x does NOT require the 601 enabler on the hard drive but does requite it on the PPC Disk Tools floppy to boot. Mac OS 8.1 does NOT require the 601 enabler at all, but on 030 Macs with the 601 upgrade you should keep a standard HFS partition with 7.6.x or a 7.6.x PPC Disk Tools floppy with 601 enabler so you can boot and switch the 601 back on in case of a PRAM zap or using the control panel to switch to 030 mode. Installing the Turbo 601 into a IIci changes the Gestalt ID to match an LC475 with 601 upgrade, thus Mac OS 8.1 installs without complaint and runs quite well even on the 66Mhz version. (It thinks it's a PowerMac 475!) Any idea what happens if the adapter is used to install the Turbo 601 into any LC 030 Mac??? (Should be the same adapter as used for the 030 PowerCache in an 030 LC.) Installing the Turbo 601 in a Performa 600 will restrict the built in video to 8bit color unless you can scrounge up the final version of the DayStar control panel. Officially you had to send the upgrade to DayStar for a ROM upgrade but poking around in the control panel with ResEdit reveals dialogs with stuff about waiting while the flash ROM is updated. My theory is that all DayStar did was stick the cards in a Performa 600 and fire it up with the final control panel revision then ship it back with a floppy with that version of the control panel. Just some of the things I learned living with a Power IIci that thinks it's a PowerMac 475. ;) ===== "The earth swarms with inhabitants.
