Why CD carriers?

CD-ROMs were EXPENSIVE! For years, the price of them was so high that institutional purchases would typically dedicate an entire PC as a player for each one. (PCs were more expensive then, also). In those days, I compared that practice to buying a movie projector for each film purchased. I remember buying a used CD-ROM play only drive for $300. I remember when the first under $2000 writer (1X) came out. But, I didn't buy one until they got down to $300. Mad a lot of coasters - the success rate was under 25% For many years, I lusted after a Qubik (sp?). That was a changer designed by Keith Henson, that had a rotating carousel style tray holding 240? CD-ROMs, mounted in a square box with from 1 to 4 drives in the corners. (SCSI drive(s), RS232 control of the changer) -- Grumpy Ol' Fred cisin at xenosoft.com
