; M7NC-1.ASM -- NCR DECISION MATE V overlay for MDM7xx. 07/01/84 ; ; You will want to look this file over carefully. There are a number of ; options that you can use to configure the program to suit your taste. ; ; Edit this file for your preferences then follow the "TO USE:" example ; shown below. ; ; Use the MDM7xx "SET" command to change the baudrate when desired. It ; starts out at 300 baud when the program is first called up. ; ; ; TO USE: First edit this file filling in answers for your own ; equipment. Then assemble with ASM.COM or equivalent ; assembler. Then use DDT to overlay the the results ; of this program to the original .COM file: ; ;============================================================================= ; ;NOTE: The use of the MDMLNK.COM utility makes the following process much ; simpler.
