Operations: Introduction: The AP64e Eprom Writer is a programer for Apple II, II+, IIe, III Computer. It offers very fast and easy programing methods through the fireware in board. Installation: To install the AP-64e Eprom Writer, simply plug it 0) as into any slot inside the apple(except slot follows 1. Turn off the power to the AppIe. This is very important to prevent damage to the computer and the AP-64e. • The DIP switch on the board will define what EPROM 2 you ore writing to set

3. To push the stick of textool down to the PCB side. Now the EPROM will be tightly held in the textool socket. Now you may key in a number from 1 to 6 to choice any function we mentioned before. Details are as follows: 1) WRITE: When you type”1”that means you will programing any a block of memory content into EPROMs. The next line come to the screen is: START ADDRESS ? just key in a start address of memory in hex code and hit RETURN. BLANK ? (Y/N) A. If you went to “burn” a blank EPROM, no

that means your EPROM not be written. as you need, please turn off the switch and change a new good EPROM and do again until you get a fully programmed EPROM. 2) READ: To instal the EPROM into the TEXTOOL and type 2, the follows will come to the screen: START ADDRESS ? $ Also please key in a start address of memory in hex code. Where wish to reed in from EPROMs. and hit RETURN. After one second, Read function finished: READ (Show on the screen) 1) WRITE 2) READ 3) COPY 4) COMPARE 5) BLANKCHE

which is inserted in the TEXTOOL. and hit RETURN SET MASTER ROM please do it, or you already have cone just hit RETURN, COMPARE OK! or COMPARE ERR!! CONTINUE ? (Y/N) Just key in “Yes” for continue or “No” to Stop it. If you want to compare two or more EPROMs, the first step is to read data from eprom t.o the memory location of your system as READ function and then set another eprom as master rom and do COMPARE function. 5) BLANKCHECK: To test EPROMS is blank or riot. please key in “5” and t
