Abstract
Abstract Modem cartridges and connection for program cartridge type computers are disclosed whereby a modem cartridge may be used in place of a program cartridge to provide the modem function between the computer and a telephone line. The modem cartridge is constructed to be interchangeable with an ordinary program cartridge whereby the modem may be electrically connected to the computer bus in the same manner as the read-only memory in a conventional program cartridge. The modem cartridge however, is provided with additional connection points which are accessible when the cartridge is in place in the computer to provide connection to a conventional phone line modular connector. The connection between the modem cartridge and the modular phone line connector may be provided by cooperatively disposed wiper-type contacts operative between the modem cartridge and contacts supported on the computer chassis positioned so as to not interfere with conventional program cartridges, with further connection being made between the contacts supported on the computer chassis and the modular phone line connector being made in computers having the manually operable cover over the program cartridge region by a thin, flat cable extending out from under the cover. Operating software or firmware for the modem may be contained in the modem cartridge or separately loaded into the computer from tape or disk.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
148 words
Modem apparatus for program cartridge type computers having at least one cartridge receptacle for receiving and electrically connecting to program cartridges, each of a predetermined mechanical and electrical connection configuration, comprising first contact means for fastening to said cartridge receptacle so as to be disposed adjacent to but not restrict the insertion and removal of a program cartridge of said predetermined mechanical configuration therein a modular phone connector coupled to said first contact means for coupling to a phone system a modem cartridge containing a modem, and having said predetermined electrical connection configuration and a mechanical configuration so as to be receivable in said cartridge receptacle to electrically connect said modem and said computer, said modem cartridge further having second contact means cooperatively disposed on said modem cartridge so as to make contact with said first contact means when said modem cartridge is inserted into said cartridge receptacle.
Claim 2
Dependent Claim
148 words
Modem apparatus for program cartridge type computers having at least one cartridge receptacle for receiving and electrically connecting to program cartridges, each of a predetermined mechanical and electrical connection configuration, comprising first contact means for fastening to said cartridge receptacle so as to be disposed adjacent to but not restrict the insertion and removal of a program cartridge of said predetermined mechanical configuration therein a modular phone connector coupled to said first contact means for coupling to a phone system a modem cartridge containing a modem, and having said predetermined electrical connection configuration and a mechanical configuration so as to be receivable in said cartridge receptacle to electrically connect said modem and said computer, said modem cartridge further having second contact means cooperatively disposed on said modem cartridge so as to make contact with said first contact means when said modem cartridge is inserted into said cartridge receptacle.
Claim 3
Dependent Claim
21 words
The modem apparatus of claim 1 wherein said modular phone connector is coupled to said first contact means through a cable.
Claim 4
Dependent Claim
30 words

Claim 5
Dependent Claim
28 words
The modem apparatus of claim 1 wherein the thickness of said modem cartridge over said second contact means is greater than program cartridges of said predetermined mechanical configuration.
Claim 6
Dependent Claim
48 words
The modem apparatus of claim 4 wherein said first contact means contains first contacts which are slightly recessed with respect to the body of said first contact means, whereby said first contacts will not be engaged during insertion and removal of program cartridges of said predetermined mechanical configuration.
Claim 7
Dependent Claim
62 words
The modem apparatus of claim 1 wherein said first contact means comprises an approximately C-shaped body disposed in said cartridge receptacle to span the thickness of said modem cartridge, so that opposite portions of said body are facingly disposed to opposite sides of a modem cartridge inserted into said receptacle, whereby said modem cartridge will be positioned by the cooperatively disposed body.
Claim 8
Dependent Claim
172 words
Modem apparatus for program cartridge type computers having at least one cartridge receptacle for receiving and electrically connecting to program cartridges, each of a predetermined mechanical and electrical connection configuration, comprising first contact body means for fastening to said cartridge receptacle so as to be disposed adjacent to but not restrict the insertion and removal of a program cartridge of said predetermined mechanical configuration therein, said first contact body means having at least a first pair of contact means therein a connector means for coupling to a phone system a cable for coupling said connector means and said first pair of contact means, and a modem cartridge containing a modem, and having said predetermined electrical connection configuration and a mechanical configuration so as to be receivable in said cartridge receptacle to electrically connect said modem and said computer, said modem cartridge further having second contact means cooperatively disposed on said modem cartridge so as to make contact with said first contact means when said modem cartridge is inserted into said cartridge receptacle.
Claim 9
Dependent Claim
172 words
Modem apparatus for program cartridge type computers having at least one cartridge receptacle for receiving and electrically connecting to program cartridges, each of a predetermined mechanical and electrical connection configuration, comprising first contact body means for fastening to said cartridge receptacle so as to be disposed adjacent to but not restrict the insertion and removal of a program cartridge of said predetermined mechanical configuration therein, said first contact body means having at least a first pair of contact means therein a connector means for coupling to a phone system a cable for coupling said connector means and said first pair of contact means, and a modem cartridge containing a modem, and having said predetermined electrical connection configuration and a mechanical configuration so as to be receivable in said cartridge receptacle to electrically connect said modem and said computer, said modem cartridge further having second contact means cooperatively disposed on said modem cartridge so as to make contact with said first contact means when said modem cartridge is inserted into said cartridge receptacle.
Claim 10
Dependent Claim
30 words
