Insert a TRSDOS diskette in Drive 0. Insert the Bedlam tape into the cassette
recorder. Make sure the cassette is fully rewound and the "Play" key is down. Press
the Reset button on the TRS-80. TRSDOS Ready will appear on the screen. Type:
TAPE (S=T,D=D)
and press [ENTER]. Press [H] in response to the Cass? question. The screen will
show:
Device = Tape to Disk
Press ANY key when Cassette ready
Press the [ENTER] key. The recorder will start and in a moment, you will see the
word BEDLAM at the bottom of the screen. The loading ** will flash in the upper
right corner of the screen. After Bedlam is saved to disk, TRSDOS Ready will
reappear. Type:
RELO BEDLAM/CMD (ADD=8020)
and press [ENTER]. After TRSDOS Ready appears, type:
LOAD BEDLAM/CMD
and press [ENTER]. After TRSDOS Ready reappears, type: [D][E][B][U][G] and press
[ENTER]. The screen will fill with numbers and letters. From this point on, do not
press any key unless you are told specifically to do so.
Press [M].
The program will respond with M ADDRESS? =. Type: [B][D][3][0] and press the space
bar once. The M (in front of the number just typed) told DEBUG that you wanted to
Modify memory, starting at address BD30. Look at the fourth line from the top of the
screen. Notice the solid white block over the first two digits (after BD30). Address
BD30 presently contains a two digit hexidecimal value. You are going to change that
value and the value of the numbers that follow.
[ENTER] is used to leave the Modify mode. Do not press Enter unless told to do so.
Type the following line exactly, without any spaces. (The numbers are shown here
separated in groups of four for ease of entry, since that is how they appear on the
screen):
