INITIAL CHECKOUT/SAMPLE SESSION
The sections that follow are designed to provide an initial checkout of the hardware/software
installation and setup and introduce you to some of the features of the TZ terminal emulation program.
1. If necessary, power-up the PC and wait for the boot process to complete.
2. Double-click the TZ icon (if you have installed the TZ Program as an icon within Windows Program
Manager).
or
At the DOS prompt (in the directory containing TZ.EXE, DISTEST.HEX, and TSTRST20.HEX), type
“TZ COM
n ” (where n is the number of the COM port to which you connected the Monitor serial
cable), then press ENTER.
3. Power-up the system.
If powering up the board from a separate power supply:
Set the voltage to +5V.
If powering up the board from your PC:
Type “V” at your keyboard.
4. Type “H” (for Help) at a Monitor command prompt to see a list of commands.
5. Type an “L”. The screen should show “Enter File Name:”
Note: Only if using the TZ emulation program only. Not available if you are using a dumb terminal
or running a PC communications program other than TZ.
6. Type “DISTEST”, then press ENTER. You should see an incrementing count. Its final value should
be followed with the message “Intel hex lines—Done” and a new Monitor command prompt:
“Z80185>”
Note: Refer to Chapter 3: “Using the Debug Monitor” if you do not get the “hex done” message.
7. Type a “U”. The screen should display the following message: “Disassemble Starting At (just
CR = from PC):”
Press ENTER to indicate that you want to disassemble from the current Program Counter value,
which was set to the start of the DISTEST program as it was downloaded.
The screen should now show a new prompt “Number of Instructions:”
8. Type “16”, then press ENTER.
A screen full of assembly-language instructions should appear, followed by another command-
line prompt.
