Example to read a 2764 made by Hitachi

(21 volt pgm voltage) and
then program an Intel 2764A. Remember that a 2764A is a 12.5 volt
part and may as well be considered as a completely different part
number even though generically (in operation) they are identical parts.
BUT they don’t program the same!!!
1. Apply power to the 9000 before you insert any parts.
2. Look for the part number in the appendix. It says to use Menu
Selection number “E”.
3. Communicate with the 9000 if you are not already (at the DOS
prompt type PGMX<cr>). Type “ME” at the PGMX eprom prompt.
4. Insert the Hitachi 2764 into the Textool socket.
5. Press ^F (hold down the control key and press the letter F) to get
the “enter command line ––>” prompter and type:
Enter Command Line ––>FILENAME [R<cr>
FILENAME is what you want the file to be called on the disk. It will
automatically have an extension of “.HEX”. <cr> means to press
the “enter” or “return” (↵)key. “R” means to read the file in the Intel
Hex format (OI to the 9000). PGMX will automatically open the disk
file (if one exists already, it will not let you destroy it) and cause the
9000 to begin sending the content of the eprom in the Intel Hex
format, which is then put into the disk file. When the 9000 has
finished sending, PGMX will close the file and return you to the
eprom type prompter.
6. Remove the Hitachi part and insert the Intel part.
7. You must now change the eprom type! Looking it up in the
manual says to use “1” so type “M1” to select “q2764A>”. It is ok to
use the “q” or “i” (toggles) on any brand part (at the eprom type
prompt), but you are more likely to get an error programming using
the “q” in the prompter if it is not an Intel part. Since this example
uses an Intel part, we won’t change it, but if for instance it was a
GI

or AMD

part, you might want to type “TI” to select the adaptive
programming algorithm (i2764A) rather than the QuickPulse algo-
rithm (q2764A).
