What are you trying to accomplish exactly?

Are you trying to repair a device where the EPROM is broken (and can't 
find another one which you can clone or so?). Any info on the specific 
device/schematic/EPROM you can share which would allow us to help you 
better?On 11/11/10 3:27 PM, mark verbos wrote:

I have a burner, but the only way I know of to create the binary files is with the Wiard/Darwin Grosse WAVE256 application. I mean, if I made some graph paper with 256 lines each way I could draw the timing that I want and then enter it line by line into WAVE256 in the "Numeric" section, but there has to be a better way. My googling has not gotten me anywhere. Does anyone have any suggestions? Chris Moore, the man behind  Ursa Major, mentions punch cards in his history section, but there must be some software...other than just HEX editors... right?
