A function specific EPLD for the PS/2 Micro Channel Bus adapter

A description is given of VLSI devices that solve the complex interface problems between the Micro Channel Bus protocols of the IBM PS/2 system and add-on boards. One of the VLSI devices described makes use of programmability to allow system designers to customize their own interface through on-chip EPROM (erasable programmable read-only memory) bits. To make the task of interfacing to the Micro Channel straightforward for the system designer, accompanying software called McMap is provided. It is a table-driven program that will lead the system designer through the specifications. A custom version of his or her own interface can be specified through programming of the on-chip EPROM arrays. Adapter description files required by the PS/2 system are automatically generated for the user to install the board
