Getting Started with ZZ80MB rev2

This guide assumes the assembly of rev2 of ZZ80MB is completed and components populated as shown in the last picture of ZZ80MB pictorial assembly guide. This guide shows how to program the EPROM and how to load software in the CF disk.

Picture below shows how ZZ80MB should be connected

Set jumper T1, T2, T9 and T10 as shown in Figure 1.

Set the terminal emulation parameters to 115200, Odd parity, 8 data bits and 1 stop bit. Power up ZZ80MB and send Tinyload.bin. Be sure to check the “Binary” box. The terminal will display the following message:

TinyLoad 1
G xxxx when done

Uncheck the “binary box” and leave it unchecked for the remaining operation; send progSST39F040.hex. When the load is completed, type “G 8000” ← upper case 'G', and 8000 will not echo back.

The following message will be displayed:

…………………………………………UX
G
ZZ80MB Programmer for SST39SF040 ver 0.1 10/1220
SST39SF040 will now be erased
Enter Y to proceed, all other keys to abort

Type 'Y' ←upper case 'Y' to erase SST39F040, then send 'ZZ80MBmon.hex'. The program is completed when “Programming is done” message is displayed. Below is a programming session as displayed on the terminal emulator.

TinyLoad 1
G xxxx when done

SST39SF040 erased, ready to upload the image file
……………………………………………………………………………………………………………………………………………………………………….UX

Programming is done

Move jumper T1, T2, T10 and T11 as shown in Figure 2

Set the terminal emulation parameters to 115200, Odd parity, 8 data bits and 1 stop. Apply power and the following sign-on message should be displayed.

The following is step-by-step procedure for preparing a new CF disk for ZZ80MB. Note for Windows TeraTerm users, here is a ZZ80MB macro that will automatically install all software in a new CF disk.

The CF disk must be initialized before CP/M files can be stored. Use the monitor 'x' command to initialize CF disk:

type 'xA' followed by carriage return to initialize drive A ← note the drive letters must be in upper case.

type 'xB' followed by carriage return to initialize drive B

type 'xC' followed by carriage return to initialize drive C

type 'xD' followed by carriage return to initialize drive D

>x clear disk directories
A -- drive A,
B -- drive B:
C -- drive C,
D -- drive D,
A press Return to execute command>x clear disk directories

A -- drive A,
B -- drive B:
C -- drive C,
D -- drive D,
B press Return to execute command>x clear disk directories

A -- drive A,
B -- drive B:
C -- drive C,
D -- drive D,
C press Return to execute command>x clear disk directories

A -- drive A,
B -- drive B:
C -- drive C,
D -- drive D,
D press Return to execute command

At ZZ80MB monitor command prompt, send 'cpm22all.hex' to ZZ80MB

type 'c2' to install CP/M2.2 BDOS/CCP/BIOS in reserved space in the CF disk

Once the CP/M2.2 is installed, the first file to load in the CF disk is the file transfer program, XMODEM:

At ZZ80MB monitor command prompt, send XMODEM.HEX to ZZ80MB

type 'b2' to boot into CP/M2.2. The XMODEM image is in RAM memory, so

at CP/M prompt, type 'save 17 xmodem.com'. This will create a file named XMODEM.COM with size of 17 records.

Use XMODEM to load a decompression program, unarj.com:

At CP/M prompt, type 'xmodem unarj.com /r', and then open the workstation's xmodem menu and send unarj.com.

At CP/M prompt, type 'xmodem cpm22dri.arj /r' and open the workstation's xmodem menu and send cpm22dri.arj.

Assuming CP/M2.2 resides on drive B,

At CP/M prompt, type 'b:' to switch to drive B

At CP/M prompt, type 'a:unarj e a:cpm22dri' to decompress CP/M distribution files to drive B.

xmodem unarj.com /r
