To chime in on the 68pin SCSI adapters/drives issue: The 68-to-50pin adapters work fairly well in external SCSI boxes ...IF the adapter + drive fits in the box. (There are some smaller inline adapters, and some shorter right angle adapters.) That's only partly the problem with use of those as internal drives in compacts.
For the compacts, another problem is termination ...a lot of the later SCSI2 drives (typically, these will be 68pin ...and 80pin SCA drives aren't terminated btw ...the SCA adapter boards are quite a bit more complex then the simpler 68-to-50s, and include provisions for termination), terminate with voltages that aren't compatible - or some kind of voltage levels issue can just be a "who knows?" one to anyone but an engineer - and they won't work internally UNLESS you ALSO use a passive terminator. I haven't come across a "known working" 50pin drive that didn't work internally though. --- brandon davis --- -- sacramento, ca -- ----- Original Message ----- 3.

The "easiest" to find have the connectors at either end of a small circuit board making the length of the adapter about two inches long. Works fine if used in something like a 6100. In other machines the extra length may interfere with proper installation of the drive. The better kind of adapter has the connectors on either side of a vertically aligned circuit board making the board fit close to the back of the drive. This type only adds about 1/2 inch to the length of the drive. Personally, I have only been able to find this type of adapter for the 80 pin drives. -- Compact Macs is sponsored by <http://lowendmac.com/>.
