* NOTE: Both the Aug 1981 and the Apr 1984 IBM 5150 Technical Reference Manuals list SW1[2] as "RESERVED",

* but the Aug 1981 edition (p. 2-28) also says SW1[2] "MUST BE ON (RESERVED FOR CO-PROCESSOR)". Contemporary
* articles discussing 8087 support in early PCs all indicate that switch SW1[2] must OFF if a coprocessor
* is installed, and the 1984 5150 Guide to Operations (p. 5-34) confirms it.
