- ; 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.
