; MXO-DB10.ASM - DYNABYTE DB 8/1 overlay file for MEX10. 06/21/84
;
; 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.
; This file adapts the Dynabyte DB 8/1 computer to the mex program.
; This version is set up to drive serial port 1. The baud rate may be changed
; to either 300 or 1200 with he "SET" command. If you need help with
; * DYNABYTE * installation you may call me after 7:00 pm @ 813-644-4060
; weekdays or anytime weekends.
; goodluck, Butch Balingit
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; Use the "SET" command to change the baudrate when desired. It starts
; out at 1200 baud when the program is first called up.
