This is a rather obscure, but very powerful, piece of hardware from the mid 1980s.
Manufactured by Central Point Software.
It is, basically, a Diskette Duplication System. It has the capability to copy copy-protected diskettes.
The Copy II PC Option Board allows you to use your IBM PC, IBM PC/XT, IBM PC/AT, IBM PS/2 Models 25 and 30, Compaq, Zenith 150, Leading Edge model D or M, NCR PC 4, HP Vectra, and most other IBM compatible computers to make archival backups of virtually all IBM PC software stored on 5 1/4 inch diskettes.
If you have an internal 3.5 inch drive, you will also be able to transfer files from your PC or PS/2 Model 25 or 30 to a Mac disk and vice versa.
The Option Board and software will give your computer the same type of disk duplication technology used by many sofware duplication firms (who put the copy protection on software in the first place).
The Option Board can also be used to successfully backup Atari and Apple 5 1/4 inch software diskettes.
This CopyIIPC Option Board comes complete with all original documentation and software.
