6. Verify the customized S-record file, C32B1.MX, by entering the command shown

below. The -DC000 offset is required to relocate the verification from the $E0000

base address of the S-records to the RAM change area at $4000.

CPU32Bug>VE -DC000<CR>

Enter the terminal emulator’s escape key to return to the host computer’s operating

system (ALT-F4 for ProComm). Then enter the host command to send the S-record

file to the port where the BCC is connected (type c32b.mx >com1, when the BCC is

connected to the com1 port).

After the file has been sent, restart the terminal emulation program by entering EXIT

on the host computer. Then enter two <CR>’s to signal the CPU32Bug that

verification is complete and the terminal emulator program is ready to receive the

status message.

Verify passes.

7. Verify the main S-record file, C32B23.MX, by entering the command shown below.

No offset is required.

CPU32Bug>VE<CR>

Enter the terminal emulator’s escape key to return to the host computer’s operating

system (ALT-F4 for ProComm). Then enter the host computer command to send the

S-record file to the BCC (type c32b23.mx >com1, when the BCC is connected to the

com1 port).

After the file has been sent, restart the terminal emulation by entering EXIT on the

host computer. Then enter two <CR>’s to signal the CPU32Bug that verification is

complete and the terminal emulator program is ready to receive the status message.

Verify passes.

CPU32Bug>

8. Follow the PROGBCC utility (available on FREEWARE) directions for

reprogramming the BCC EPROM using the two S-record files, C32B1.MX and

C32B23.MX.
