:Bringing CP/M 2.2 up on the Thinker Toys Single Density Disk Jockey

1. Modify TTCBIOS.ASM for your console and other I/O

2. Make sure that MSIZE is set equal to 20 in both TTCBIOS.ASM & TTBOOT.ASM

3. Assemble both TTCBIOS & TTBOOT

4. You will need a copy of a 20K version of CP/M 2.2, use SYSGEN to get a
   copy off of your master CP/M disk and save it as a COM file:

	A>SYSGEN
	SOURCE DRIVE (OR RETURN TO SHIP) B
        SOURCE ON B, THEN TYPE RETURN
	FUNCTION COMPLETE
	DESTINATION DRIVE NAME (OR RETURN TO REBOOT)

	A>SAVE 35 CPM20.COM

5. Now we can insert our 'customized' boot & cbios into this 20K version
   of CP/M using DDT.COM:

	A>DDT
	DDT VERS 1.4
	-ICPM20.COM
	-R
	NEXT  PC
	2400 0100
	-ITTBOOT.HEX
	-R880
	NEXT  PC
	2400 0100
	-ITTCBIOS.HEX
	-RD580                  (for systems larger than 20K this value will
	NEXT  PC		 change. Use the value of OFFSET from TTCBIOS)
	2400 0100
	-^C
	A>SAVE 35 CPM20NEW.COM
	A>SYSGEN CPM20NEW.COM 	(Put a clean disk to receive the new CP/M 2.2
	SYSGEN			 system into drive B)
	DESTINATION DRIVE NAME (OR RETURN TO REBOOT)B
	DESTINATION DRIVE NAME (OR RETURN TO REBOOT)
	A>

6. You should now take your 'new CP/M 2.2 disk' from drive B, insert it
   into drive A, and boot your system.  

7. Your CP/M 2.2 Single Density Disk Jockey system should sign on.

8. Now try saving files with the save command and see if they appear in
   the directory.  Try using ^C to Warm boot.  If everything works ok,
   you're on your way with CP/M 2.2 on the DJSD system.

:Author / Programmers Credits


	Full credit should be given to the original cbios and hardware
creators:

		Thinker Toys
		5221 Central Ave
		Richmond, CA 94804

	
	The original CP/M 1.4 cbios was re-written / modified for CP/M 2.2
and minimized to fit smaller area provided by CP/M 2.2 (compared to 1.4) by:

		Jack Burge
		518-A Fifth Street
		East Northport, NY 11731


	The MSIZE, DELTA, CCP Equates to allow easy changing of the system
size came from excellent software written by:

		TKI   (The Kendall Institute)
		Bruce Kendall
		334-A Camille Ct
		Mountain View, CA 94040
	

	All I did was put everything together, patching TKI's equates into
software re-written by Jack Burge.  These equates by TKI REALLY simplify
changing system size.  The ideas and design of the section 'Bringing CP/M 2.2
up...' is from Bruce Kendall.  I liked Bruce's design, so I used it.

	I also created this hlp file and accept a small credit for the ease 
with which this software can now be implimented following the instructions
in this file.  It wasn't so quick or easy for me.  I'm trying to make it easier
for others.  I hope I have succeeded.
