; MXO-SB12.ASM - Intertec Superbrain overlay file for MEX10.  09/25/84
;
; 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.
;
;NOTE:
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; Use the "SET" command to change the baud rate, word length, parity,
; or stop bits for the main port. 
;
; Added a LISTST routine so the print buffer stuff would work.
