There is a problem with the Unimac sliding red aluminum brackets which may or may not effect your enjoyment. On other brackets I've seen, the drive is shifted slightly to the outside of the computer case, placing the actual mechanism farther away from the CRT. The UniMac bracket actually shifts the drive inboard some, making it sit right next to the CRT. In this case, "right next" equals about 1/8", best case. The problem with this is that one of the motors in the Quantums is near that corner of the drive which is closest to the CRT. It can cause a very noticeable interferrence pattern on the screen during disk access. I have never noticed this interferrence on the outboard-shifted brackets (from MicroNet, in this case). Another gripe about the UniMac bracket is the overall sturdiness of the design. I would call the design "inexpensive to manufacture and just marginally adequate to use". The drives I have received from MacLand in Quantum boxes with UniMac software and (I assume) UniMac brackets have the "shoe" already tightly screwed to the drive. This is fine except that the jumpers to set drive ID are under that shoe and come preset to ID=6. For consistency sake, all internal drives under my control are set to ID=0 and I need to remind myself to disassemble the bracket and change the jumpers. I've forgoten this more than once!
