Getting Started with CB030, Rev1

This guide assume you already have a fully assembled CB030 rev1 as shown in the picture above.

The console serial port is the CP2102 USB-serial adapter soldered directly to the CB030 board. Set the terminal emulator to 38400 N-8-1. Hardware handshake is not absolute required to operate CB030; the processor is fast enough to support Kermit file transfer without handware handshake.

CB030 requires regulated 5V, 1amp. The power plug is 2.5mm X 5.5mm which is not compatible with the more popular 2.1mm X 5.5mm connector.

Apply power to CB030 and the following message will display after about 1 second delay:

Please refer to CB030 Monitor manual for description of various monitor commands.

To run CP/M68K from the monitor, type 'bo' and the CP/M68K A> prompt will display

Drive A is read-only drive reside on EPROM. It contains the formatting software, 'init.68k' and file transfer file, 'gkermit.68k'

Drive B-E are 8-megabyte read-write drives reside on compact flash disk. The assembled and tested CB030 includes a CF disk already formated and loaded with CP/M68K distribution files.

A new blank CF disk needs to be formated first and then loaded with CP/M68K files. Since drive A already has the init.68k and gkermit.68k, it is easy to format and transfer files to a new CF disk.

To format a new CF disk, type:

init b:

init c:

init d:

init e:

CP/M will ask you to confirm, press 'y' to go ahead with the format command

To transfer file(s) with gkermit to a read-write drive (drive E in this example), type:

e:

a:gkermit -r

Select kermit protocol in your serial terminator emulator and send one or more files (in TeraTerm: File → Transfer → Kermit → Send, then pick the file or files to send).

First, change to a new drive and copy CP/M files to it:

pip b:=e:*.*[v] ← this command copies all files from drive E to drive B with verify

To run microEMACS, type:

me hello.c

The microEMACS screen editor will open with a blank screen, type:

main()

{

printf(“Hello World”);

}

ctrl-Z to save and exit microEMACS

To compile the Hello World program, type:

c hello

To link the Hello World program, type:

clink hello

to run the new Hello World program, type:

hello
