[sdiy] working with EPROMs

[mark verbos]

Hi guys,


I've been looking at some 70s delay schematics that use EPROMs to create all of their timing signals for the converters and rams and everything and it makes me wonder how you create the data for those. 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?


Thanks,

Mark
