This is the Firmware for the Novation AppleCat II Modem. We don't know too much about what this Firmware allowed the AppleCat II to do, but we do know how hard it is to find today.
The ROM file is also available >HERE< for free if you wish to burn your own.
Tip from Kevin Rauer (6-14-6): The AppleCat II Firmware allows one to interact with the modem via a 'PR#x' (x=Slot Number) command to initialize the card. Then using control characters you can control the modem. A good Site with files for the AppleCat is: >The Novation AppleCat ][<
Despite the APPLE-CAT II's popularity, its early years were faced with incompatibility with most telecommunications programs, as its native API is considered proprietary by today's standards. To increase compatibility without re-coding these programs, Novation released a firmware upgrade kit (an EPROM package) allowing the modem to emulate the Hayes Micromodem II, including the MMII's IN#x control codes. At the APPLE-CAT II's peak, compatibility with its native API increased, and MMII emulation became less of a necessity.
