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

into any slot inside the apple(except slot 0) as follows

1.Turn off the power to the AppIe. This is very

important to prevent damage to the computer and the AP-64e.

2 • The DIP switch on the board will define what EPROM you ore writing to set DIP switch as following

Please Confirm DIP’ switch must beset right as above chart, otherwise EPROM could be damaged.

3.Remove the cover from the Apple. Inside along the rear edge of the circuit board, is a series of eight long narrow Sockets. called "SLOTS". Insert the AP64e into any slots except the left one with a gentle rocking-motion until fully Seated.

4.Now, turn your Apple on. Type PR#n (n is slot

number). or type IN#n lnteger Basic) From

the monitor(whose prompt character is *), you type CsØØG or s "CTRL P (s is a sIot number).

Functions: There are six. functions for AP-64e EPROM WRITER: 1. WRITE: Program any a block of memory content

into 2716, 2732 or 2764.

2.- READ: To move EPROM memory content to RAM location ,

3.COPY: Duplicate content. of master ROM Into copy

EPROMS.

4 COMPARE. TO verify 2 blocks of memory between systems and EPROMS.

5.BLANK TEST: Test 2716, 2732 and 2764 is blank or not.
