BROWSE IS A COMMAND-LINE PROGRAM TO ACCESS THE SUBROUTINES. THEY
ARE CALLED BY THE FIRST KEY AFTER THE PROMPTS; NO CR IS NEEDED.
MANY FUNCTIONS NEED THE P(PARAMETER), B(BEGIN ADDRESS),E(END
ADDRESS) OR T(TO ADDRESS) SET UP FIRST BY KEYING P,B,E or T AND
THEN THE HEX CODE AFTER THE PROMPT. THE M VALUE IS THE CONTENTS
OFTHE T ADDRESS LOCATION. THE FOLLOWING COMMANDS ARE
IMPLEMENTED:
# COMPARE Displays the differences between the programs
between Band E and the same lengthstarting
at T. P=17 on Console,or 03/12 on Host.
@ Run the program at B000
* LD-HOST Loads a .F8D format program from host at P baud
into memory at B, which must agree with S=XXXX.
P values are 03(300),12(1200) or 96(9600).
~ Run the program at 600
+ INC-ADDR Increment B to address following next' lA'
- DEC-ADDR Decrement B to address following previous 'lA'
1 19200 Run from Console at 19200 baud
2 1200 Run from Host at 1200 baud
3 300 Run from Host at 300 baud
4 SAY-TIME Says the 24-hour time.
7 Run the program at 700
S Run the program at 8050
9 9600 Run from Console at 9600 baud
< lKRAM Enables lK RAM for writing
= lKRAM Shows state of lK RAM
) lKRAM Disables lK RAM for writing
I HEX-DUMP Show block of memory in hex starting at B
A STO-STR Set P=42 and clear memory first. Input to memory
at B in ASCII until a AZC' 1A') is keyed. E is set
to address after the' lA'.
B SET-B Last 4 hex digits form B address
C COpy Copies up to 4K from B to E, inclusive, to T
unless T ) FF00. T is. set to next free address.
D BACKUP Dumps memory from B to E, inclusive in hex to Host
at P baud in .FSD format.
E SET-E Last 4 digits form E address
F FILL-MEM Fills memory from B to E inclusive with zeroes.
The location at B gets a 'lA' code.
G EXEC-DC Runs the program pointed to by th~ B address
H HEX-DEC Converts input in hex to decimal for each '='
Goes to address 0 for a CR.
I PATCH Search and replace in range B to E. P=00 for hex
or P=50 for text. Key S for search string. For hex
separate bytes with spaces. End search string with
a comma. Key R for replace string. A CR starts the
search. For each match key R to replace, or CR to
go on to next match without replacement.S bytes
max string length.
K TABLE Displays B to E in various formats depending on P
In particular,P=00 for hex and P=40 for text.
L EXT-LOAD Loads .FSD format files into memory at B from
host. This command must ,be executed from the Host.
B must agree with S=XXXX
M SET-M Inspect and change memory at T. Put in hex to
change. Key CR for next location, Up-arrow for the
previous location. Key. to return.
N DRAWCHAR Reads ZRT-80 character generator EPROMS. Shows 15
characters enlarged,starting at B. Commands ·are CR
for another 15,'-' for previous 16,'.' to return.
P SET-PARM Last 2 hex makes P value
Q DISTRIB Displays distribution of values between Band E-1
If p=00 hex,P=01 unsigned decimal,P=02 signed
decimal,else in characters and hex for non-print
Location 4C2C should be '80'
R RDSOURCE Loads .F8S files into memory at B from Host at P
baud (03=300, 12=1200 or 95=9500). B does not have
to equal the @XXXX. XXXX goes into T and actual
end address goes into E.
S SOURCE Dumps from B to E inclusive to Host in .F8S format
at P baud.P=03 for 300,P=12 for 1200,P=95 for 9500
or P=17 to display on Console.
T SET-T Last 4 hex becomes T address
U LD-INTEL Loads memory at file address plus B address from
Host at P baud.P=03(300),12(1200) or 95(9500).
The file is in Intel hex format. Errors are put
into memory at T to avoid loading host.
W BITCOUNT Adds bit values f1"~om B tCI E irlclusive 1"~ega1"~dless
of bit position in byte. P=00 counts 1 bits,P=0l
c':ltmts 0 bits.
X DISP-STR Set P=A0 to display text fromB address tQ next
'lA'. Set P=18 for Console to/from Modem. P=19
stores modem data also at B. Many other valid P
values. Return with a AZ.
Z EPROM-WR Dumps memory from B to E into EPROM, starting at
EPROM location T. For P=00 copying is forwards,
or P=FF to complement addresses to the EPROM.
[ EPROM-CP Loads memory at T from addresses B to E-1 in EPROM
in burn socket. P=00 for forward copy,P=FF to
complement EPROM addresses. (Not made here).
A STOINTEL Dumps from B to E at P(03,12) baud in Intel hex
format, addresses starting at 100.
_ PORT Puts P into port 1, then the most significant byte
of B into port 4, puts port 0 into the LSB of B
