- Martin,
-
- It seems to me you have done extensive troubleshooting...have you
- contacted Utilities Unlimited about your SCSI problem? You are aware
- that your Emplant has a lifetime warranty, right? While I have found
- that their product has occasionally been less than 100%, I have found
- that their customer service is excellent.
-
- The Mac Pro emulation is up to version 1.3 now and while your mileage
- may vary, I have found it to be an excellent product. Of course, a MMU
- is required for Mac Pro, so you would have to consider the cost of that
- upgrade before spending the $34.95 (?) on Mac Pro.
