I was just thinking again about Micropolis, due to it being mentioned in this thread, and realized that they were located in Chatsworth, and CMI was also located in Chatsworth. Not that there was any connection between the two, AFAIK. Anyone here ever used a CMI drive? After the IBM fiasco with CMI drives was first being discussed, I personally stayed clear of all CMI drives. I delayed getting my IBM PC AT until things played out, and I was guaranteed of getting a non-CMI drive. I guess that was enough to cause the company's demise, as it wasn't long after that where I never heard of them again.
From my perspective, Micropolis was a well trusted brand, and CMI was bottom of the barrel. Complete opposites.
