Ripley's Believe It or Not!
Stern, 2004Depending on if the upper address lines are tied high/low on the board, you can simply quadruple the image size and then burn it to your 4mbit eprom. If the upper address lines are floating on the board, you would need to either modify the board or the eprom itself to pull them high or low.
On windows:
copy /b image.bin + image.bin + image.bin + image.bin image_4x.bin
To create an image 4 times the size of the original. Then you would burn image_4x.bin to your 4mbit eprom.

Oh! That means that I can still use the 27c4001 since it is a 4mbit. I got to try it 
This is very cool!! So using the above command, I can create a new file with 4 images. Then write to chip...
It works! WOW thank you for the info.

Not sure how to check this, but the above command worked great.
