I have a MacPlus, with 4MB RAM, that used to run off a Jasmine 100MB HD. That drive finally gave up, and I'm trying to utilize the SCSI2SD v5.5 as a replacement. I've been Googling different forums, and can get a .dsk with a partial 6.0.8 system to boot and run (off a 2GB image), but if I try to modify that by doing a full 6.0.8 install, or upgrading to 7.1 (I have the install floppies), I get error messages. The same source (SavageTaylor.com) has a 7.5.5 image, but that won't boot. There are specific settings for the MacPlus to be able to use the SCSI2SD board, and I've applied them.
