; MXO-II12.ASM-- InterSysytems VIO and H-Z19/29/49 file for MEX. 06/08/84 ; ; 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 places particular emphasis on using the InterSystems VIO with ; the 2651 PCI and the H-Z19. Much of the information contained here is ; not in the main file. If you're not using the above named equipment, ; some of the routines here may give you some hints for your MEX patch. ; ; Use the "SET" command to change baud rate when desired. ; ; Edit this file for your preferences then follow the "TO USE:" example ; shown below. ; ; ; TO USE: First edit this file filling in answers for your own ; equipment. Then assemble with ASM.COM or equivalent ; assembler. Then use MLOAD to overlay the the results ; of this program to the original .COM file. ; ; ; = = = = = = = = = = = = = = = = = = ; 06/08/84 - Changed to MEX labels MXO-II12.ASM - Len Moskowitz ; 06/04/84 - Changed to VIO/Z19 - MXO-II11.ASM - Len Moskowitz ; 05/23/84 - Corrected clear-screen error - Biff Bueffel ; 05/19/84 - Converted for MEX10 - MXO-H811.ASM - Biff Bueffel ; 11/11/83 - Renamed to M7H8-1.ASM, no changes - Irv Hoff ; 07/27/83 - Renamed to work with MDM712 - Irv Hoff ; 07/01/83 - Revised to work with MDM711 - Irv Hoff ; 06/22/83 - Revised to work with MDM710 - Irv Hoff ; 05/27/83 - Revised to work with MDM709 - Irv Hoff ; 05/15/83 - Revised to work with MDM708 - Irv Hoff ; 04/17/83 - Revised to work with MDM707 - Irv Hoff ; 04/04/83 - Updated to work with MDM706 - Irv Hoff ; 02/27/83 - Updated to work with MDM705 - Irv Hoff ; 02/17/83 - Updated to work with MDM704 - Irv Hoff ; 02/07/83 - Updated to work with MDM703 - Irv Hoff ; 01/27/83 - Updated to work with MDM702 - Irv Hoff ; 01/10/83 - Updated to work with MDM701 - Irv Hoff ; 10/03/82 - First version of this file ; ; = = = = = = = = = = = = = = = = = ; BELL: EQU 07H ;bell CR: EQU 0DH ;carriage return ESC: EQU 1BH ;escape LF: EQU 0AH ;linefeed ; YES: EQU 0FFH NO: EQU 0 ; ; ; VIO base address and port offsets.
