E9BUF.BAS - A PROGRAM TO DEMONSTRATE THE USE OF THE BOOT MODE
REQUIRES THAT THE S-RECORDS FOR BUFFALO (BUF34.S19)
THIS PROGRAM HAS BEEN RUN BOTH ON A MS-DOS COMPUTER
ON THE HC11 BY PROGRAMMING AN HC711E9 WITH
BUFFALO 3.4
BE AVAILABLE IN THE SAME DIRECTORY OR FOLDER
USING QUICKBASIC 4.5 AND ON A MACINTOSH USING
QUICKBASIC 1.0.
'STRING TO USE FOR HEX CONVERSIONS
'NUMBER OF BYTES IN BOOT CODE
'BUFFALO 3.4 IS 8K BYTES LONG
'INITIALIZE BOOTCODE$ TO NULL
'# OF BYTES IN BOOT CODE
'CONVERTS HEX DIGIT TO DECIMAL
'HANG ON TO UPPER DIGIT
'DEFAULT FILE NAME FOR S-RECORDS
'GET 1 CHARACTER FROM INPUT FILE
'FLAG IS EOF FLAG FROM SUBROUTINE
'RETURNS DECIMAL IN X
'BUILD BOOT CODE
