Procedure for install a new CF disk
Install CP/M-68K in new CF track 1
- Insert a CF disk in the adapter. WARNING: the content of the CF will be erased.
- clear the memory from 0x15000 to 0x20000 with the program “clrcpmmem.s68 ”. Use the “send text file” command of your terminal program to upload. This program will auto-execute when file loading is finished. When program execution is completed it will display “S record execution completed” and prompt for more inputs. Please note that source & listing are included in the zip file, only upload the file with .s68 extension.
- upload “CPM15000.s68 ”. This is the CP/M-68K CCP and BDOS. Wait for the input prompt after about 15 seconds.
- upload “tinyBIOS.s68 ”. This is the BIOS specific to the Tiny68K
(11/14/17, link is updated with rev5 BIOS)(3/20/18, link is updated with rev6 BIOS) - lastly upload “writeBoot.s68 ”. This will write CCP, BDOS, and BIOS into track1 of CF disk.
- execute the monitor 'bo' command. This will copy the software in track 1 to memory starting at 0x15000 and then jump to it. A checksum will be displayed which should be '0C0DCC9E' and CP/M 'A>' prompt should be displayed. A CPM 'DIR' command may display random data because there are no meaningful directory structure in the CF at this time. When 'DIR' command is executing, the tiny red LED on the 44-pin CF adapter should flicker indicating access to CF.
Below is a screen shot of the installation of CP/M-68K in track 1 of a new CF
Load CP/M-68K distribution files into RAMdrive
Cycle power or press the reset button. Upload the RAMdisk image 't68kram.s68 '. This will take 30 minutes to complete. t68kram.s68 contains the files from CP/M-68K ver 1.3 distribution disks plus microEMACS, gkermit, and BASIC executables. All executables are in relocatable format and will be converted to .68K executable format.
Copy the CP/M distribution files into the new CF disk
when the RAMdisk image load is completed, execute the monitor command 'bo'. The CP/M should boot with a 'A>' prompt.

Test the newly created CF disk:
When copy is completed without any errors do the following quick tests:
A: switch to drive A as the default drive
ME README.TXT Executing microEMACS to edit README.TXT. The command summary is documented in ME.TXT. Test drive it and exit without modification with ctrl-x ctrl-c key sequences.
ME HELLO.C Create a C program–Hello World in microEMACS
main(){
printf(“Hello World”);
}
ctrl-z to save and exit microEMACS
C HELLO Compile the Hello World program
CLINK HELLO Link the Hello World program and generate HELLO.68K
HELLO Execute the Hello World program, should see Hello World
CB68 ASCIIART Test the BASIC compiler
LINK68 ASCIIART,CB68.L68 Link the BASIC program and generate ASCIIART.68K
ASCIIART should display the following screen:

AS68 -U -L -S 0: FCOMP.S Create a file comparison program for subsequent testing
LINK68 FCOMP Link the file comparison program and generate FCOMP.68K
GKERMIT -S README.TXT Use gkermit to transfer a text file to PC. In the terminal program enable 'receive file' with kermit protocol. Hardware CTS/RTS handshake must be enabled otherwise file transfer will not be successful.
INIT B: initialize drive B
B: Drive B is now the default drive
A: GKERMIT -R Transfer file from PC to drive B. In the terminal program enable 'transmit file' with kermit protocol. Transmit the “README.TXT” file that was received previously.
A:FCOMP README.TXT A:README.TXT Compare the file received with the original. Two files should be the same.
This concludes the quick tests. Your Tiny68K with CP/M-68K is in operation!
This is the CP/M68K v1.3 distribution files. They can be loaded individually or multiple files using gkermit.
