; M7H8-2-1.ASM -- Heath/Zenith H8/H89 overlay file for MDM7xx.COM ; ; 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 Heath/Zenith equip- ; ment with 2651/2661 PCI serial I/O. Much of the information contained ; here is not in the main file. If not using the Heath H8, H89 with ; 2651, or 2661 PCI I/O, but with the 8250 serial I/O, then use M7H8-1. ; ASM overlay. If not using Heath/Zenith equipment, some of the rou- ; tines here will illustrate what you could do with your equipment. ; ; ; Use the "SET" command to change baudrate 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 DDT to overlay the the results ; of this program to the original .COM file: ; ; A>DDT MDM7xx.COM ; DDT VERS 2.2 ; NEXT PC ; 4A00 0100 ; -IM7H8-2-1.HEX (note the "I" command) ; -R ("R" loads in the .HEX file) ; NEXT PC ; 4A00 0000 ; -G0 (return to CP/M) ; A>SAVE 73 MDM7xx.COM (now have a modified .COM file) ; ; NOTE!: Be sure to check the NEXT address above with what you get ; when you load MDM7xx.COM with DDT. If the two addresses ; differ, you need to adjust the number of 'PAGES' to SAVE ; by the amount of the differance. If the address you get ; is larger, then add the differance to the number of pages ; to SAVE. If it is smaller, then subtract the differance. ; ; = = = = = = = = = = = = = = = = = = ; ; 13-MAY-86 - Revised to work with H8 / H89 2651/2661 PCI USART - WEA ; 06-APR-86 - Updated to work with H8 2651 I/O.
