When you&#x27;re having a good time a &quot;few years&quot; is pretty short. :-)<p>Our RM80&#x27;s were trouble free from what I can remember. We had an air conditioned, electrostatic filtered clean room for our systems which also included some PDP11&#x27;s and PDP11&#x2F;40&#x27;s with RL02&#x27;s and RK07 disk drives. The room had very limited access and you had to wear booties. The only time we lost a drive is when one of the RK07&#x27;s went crazy, slamming the heads against the hard stops causing the heads to crash onto the disk.
