The Turbo 601 for the IIci was also sold for the IIvi and IIvx, but there was a bug in it that limited their onboard video to a max of 256 colors. Since the T601 was designed before the release of the vi/vx, DayStar never considered anything about onboard video that would do 16 or 24 bit color. After shipping off the Turbo 601 to Daystar, it would come back with a different version of the control panel, along with allowing the IIvi/vx onboard video to work properly. I've yet to find a copy of that version of the control panel. When I picked up my "Power IIci" with a 66Mhz T601, 32megs RAM and a 500 meg hard drive (for a whopping $10) I only had a 12" Apple color monitor. The T601 control panel window was designed for a minimum of 640x480, so I poked around in it with ResEdit and found a couple window resources with text about flash RAM. I bet the fix for the IIvi/vx was a simple matter of plugging the Turbo 601 into one of those Macs with the "special" version of the control panel, enabling it then rebooting and watching the control panel flash the ROM. What I've not been able to find out is how the Turbo 601 will work (if at all) in a IIci after being flashed with the fix for the IIvi/vx. At any rate, the built in SCSI Manager 4.3 in the Turbo 601's ROM seems to be useless. When enabled and Mac OS 7.6 installed, no software that requires SCSI Manager 4.3 will run, claiming it's not present. System 7.5.0 is supposed to install the SCSI Manager 4.3 Extention on Macs that do not have it in ROM, but apparently that only applies to 040 Macs prior to the Centris 610, which was the first to have it in ROM. System 7.5.1 and up integrate SCSI Manager 4.3 into the System file if it's not in ROM, but again apparently only on 040 Macs. Installing the SCSI Manager 4.3 Extention from 7.5 does not work, with or without the ROM version on the Turbo 601 enabled. Apps that require it still insit SM4.3 is not present. Apparently they can detect the base machine is an 030, not an 040 and from that refuse to acknowledge SCSI Manager 4.3. Also, Apple's 601 Upgrade Control Panel will only _disable_ the Turbo 601. When attempting to _enable_ it, it returns an error that it only works on Macs with a 68040 CPU. Thus the Daystar control panel is the only thing that can enable the Turbo 601. The Apple or Daystar control panel will work on the Power Pro or Power Card, which were made for 040 Macs. Unlike the 030 Universal Powercache, the Turbo 601 does NOT need the control panel once it's been enabled. The PRAM is patched so that the 601 is activated immediately upon power up. Zapping the PRAM kicks the Mac back to the 030 CPU. Mac OS up to 8.6 has been hacked to install onto a IIci with a Turbo 601. Attemps to hack OS 9.x onto the Turbo 601, Power Pro and Power Card appear to have been abandoned. ===== "You never have to repair or replace what you leave out of the design."
