This Autopatch tape includes the TOPS-20 Monitor Table Descriptions manual. This manual provides detailed text descriptions of internal monitor tables. Each table is displayed showing its storage locations. Table and section lengths are defined. All symbols, pointers, and displacements are defined to indicate their table word offset and values. Where applicable, field symbols and their bit values or contents are defined with their on/off status. Appendix A provides an alphabetical list of monitor tables within their defined modules. The TOPS-20 Monitor Table Descriptions manual can be printed out on any available line printer. The file does contain wide examples, so plan to print on a printer that will accomodate the wide examples.
