Ah, the 1990's. When they wouldn't trust us to insert a CD-ROM into your drive without placing in one of these convenient 'caddies' in order to prevent the usual man-handling. This one housed my ancient copy of TurboTax 1995, which is still encased, safely, in all that plastic. If only I had a drive capable of accepting caddies like this. Oh well. I can just open it up and get out the old CD-ROM, if it wasn't over 13 years old, therefore useless to file taxes I'm not liable for anyway.
