PREPARING ZCMD FOR RCP/M USAGE
                    (EPSON QX-10 AND CP/M B2.20)

Installing ZCMD on the Epson QX-10 is a relatively easy task,
especially when the ZCMD.HEX file is already prepared.  The task is
presented below as a series of numbered steps.  Just execute each step
in numerical order and no problems should be encountered.


1. Copy the following files to a seperate 'work' disk.

   a. STAT.COM
   b. DDT.COM
   c. CPM2.SYS (B2.2n) using COPYDISK to copy system tracks.
   d. SETUP.COM (for B2.2n)
   e. ZCMD.HEX

2. Use STAT.COM to make CPM2.SYS read-write:

   A>STAT CPM2.SYS $R/W <RETURN>

3. Use DDT.COM to load CPM2.SYS in memory:

   A>DDT CPM2.SYS <RETURN>

-----------------------------------------------------
++ STEP #4 IS *ONLY* FOR CPM B2.20 ++

4. At the '-' prompt enter the following:

   S1FCD <RETURN> 	(screen will display following):

   1FCD  ED  00		(You enter the 2 zero's and then RETURN)
   1FCE  B0  00		(You enter the 2 zero's and then RETURN)
   1FCF  3E  .          (You enter a dot and RETURN to end changes)
-------------------------------------------------------

5. At the '-' prompt enter the following:

   IZCPR.HEX <RETURN>	(reads filename into FCB)

   R2800 <RETURN>	(loads ZCPR.HEX at indicated offset)

   ^C			(Enter control C to exit DDT)

6. Use SAVE command to save modified CPM2.SYS file:

   A>SAVE 205 CPM2.SYS <RETURN>    For CP/M B2.20
   A>SAVE 177 CPM2.SYS <RETURN>    For CP/M B2.25
   A>SAVE 196 CPM2.SYS <RETURN>    For CP/M B2.26

7. Press the RESET button and ZCMD will become active and permanent.
   The A0> prompt should apppear if all went well.

8. SETUP must be evoked to set new defaults for the modified CPM.

   A0>SETUP <RETURN>   	(Set the following options):

   A. DISPLAY OPTION	

     3. BIT 7 MASKING			DISABLED

   E. DISK SUBSYSTEM

      1. DIAGNOSTIC ERROR MESSAGES	DISABLED

      2. STANDARD DISK ERROR RETRY	DISABLED

      3. RAM DISK 			AS DESIRED

   G. SERIAL PORT

      2. LINE PROTOCOL			NONE

      6. BIT 7 MASKING			DISABLED

      7. INTERRUPT DRIVER		DISABLED

9. Exit SETUP with 'P' option to make changes Permanent.

10. ZCMD is now ready for RCP/M usage.
