Very, very nice... are you planning to sell this (in either kit or assembled form)?

>> OK, maybe a simpler question: how do I copy the B: drive to another compact flash so that I can test that device?

The way I do it is with "dd" on a Linux system. I think there are "dd" work-alikes for WinDoze, but I don't know anything about them.

1. figure out the length of your A: drive in 512b sectors. Call it 'X'
2. run "dd" as follows: dd if=<my_CF> ibs=512 of=b_drive obs=512 skip='X' count='X'
3. if your system swaps bytes, you might have to add conv=swab to the above to swap bytes.
4. at that point you have the "B" drive in the file "b_drive" (I'm assuming that the count of 512b sectors in A == B).
5. copy "b_drive" (the file) to a new CF with: dd if="b_drive" ibs=512 of=<new CF> obs=512.

If you can set up the cpmtools application, you could extract the individual files from "b_drive", if you'd like to.

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.
