- :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.
- :Files Required

- :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.
