The Sparc 5's and 20's actually use a drive cage like the ones fitted to the
Ultra-1's, and 2's in that it accepts two SCA SCSI (ie. 80 pin) drives
fitted into special mounting frames, but the caveat is that the SCSI
controller is *not* wide, it's only narrow, so yes, you can use just about
any 3.5" SCSI drive that you care to install, buy you won't get blinding
performance.

I think it's only the Ultra-1/140E, 1/170E and the Ultra-2's which had wide
SCSI on-board, so they probably do run a 16 bit SCSI data bus to the SCA
cage.

Craig.
