Ah I never saw the 8" ones, jsut the ones that were probably like 5.25" or

Awesome! The 44Mb (and maybe 88Mb?) ones I dealt with were as a young lad 
working at a government contractor on a Navy base. The command there used 
them for the secure messaging computers. They would toss the classified 
ones in the safe and have me fix the unclass one, write down what I did 
then do the same on the classified ones.

When I was young DOS kid I always thought the removable cart "hard drives" 
seemed better than a normal hard drive because ou could expand it. Didn't 
know about access times. Later had a zip drive, they were cool.

I still have a few Zip drives and a Jaz drive somewhere, freebs picked up 
along the way years later.

I did have a SCSI 100Mb zip in a music sampler box that click of deathed 
on me when I needed it the most.

Young and dumber (maybe) I had sampled a few clips from the movie 
"Contact" of the little girl saying like "CQ CQ this is blablabal" and 
what not. On the EMU sampler you didn't need midi device to drive it, 
there was 10 number buttons on the front you could assign it to. So I 
assigned these girl-on-the-ham-radio samples to the buttons, threw it in 
the car with something programmed to xmit on the hamfest repeater freq and 
an inverter... with the idea I would toy with the hamfest hams and give 
them some excitement. Arrive to the Virginia Beach hamfest and sure enough 
the zip drive click of deaths on me. It was never ment to be.
