works on any Apple Mac, or Power Mac, except the 128k, 512k, and plus.  Requires System 7 or later and 4 MB ram.

I bought this new in the 90's for a mac, I never used it, it;s been on my shelf in 6 housed and never out of the box.

Took it out of the box for testing and powered it up to be sure. It works.

14.4 fax modem for older macs. (note the mac serial connector)

Still has the AOL and Compuserve floppy disks with it.
