Welcome to the MCA Area 51 website!

On this website, you will find information relating to various projects I am working on related to IBM's PS/2 computers with the MCA bus. For the uninitiated, MCA stands for MicroChannel Architecture and PS/2 stands for Personal System/2.


I wish to thank many people for supporting these efforts. First, my wife for her patience and understanding of my fondness for the IBM 9595. Second, members of comp.sys.ibm.ps2.hardware, namely, Charles L. for tolerating my questions and Louis O. for being ardent in his quest for MCA superiority. Third, Kevin B. for being open to re-hosting this information. Finally, those few companies who still sell and support the MCA bus - they do exist, just requires diligence.
