Mike,

You'll find the following files on drive A: which is a read-only drive reside on the EPROM, so they are always there even without a CF disk

A>dir
A: ME       68K : GKERMIT  68K : AS68SYMB DAT : DDT68000 68K : DDT      68K
A: PIP      68K : INIT     68K : STAT     68K : AS68     68K : LINK68   68K
A: DUMP     68K : LO68     68K : ED       68K : AR68     68K : MORE     68K
A: FIND     68K
A>

The three particularly useful files are PIP, INIT, and GKERMIT. When you insert a new CF disk, you first initialize it with "init b:", "init c:", init d:", and "init e:" to clear out the directories of four 8-meg disks on CF. Then you can do "pip b:=a:*.*[v]" to see if files can be copied correctly from ROM drive to CF drive. If that's successful, then you can use GKERMIT to transfer files from your PC to CF drives.

To use GKERMIT to transfer files from you existing CF disk to PC, type:
a:gkermit -s filename <- the filename can be wildcard, so it can be *.* to transfer the entire disk to PC
on terminal emulator, look for the kermit transfer protocol and enable file receive. For TeraTerm it is File->Transfer->Kermit->Receive

To transfer files from PC to CB030, type:
a:gkermit -r
on the terminal emulator, look for the kermit transfer protocol and select file send. For TeraTerm it is
File->Transfer->Kermit->Send then select the file(s) to send.
