    as i can somewhat understand the workings of a rom i need help actually MAKING one

    i basically need help understanding how to take a "Blank" one and edit it so that say input A results in output B

    if you can help that would be great

    EDIT: as i look at an existing rom i can see the workings better but i still need help understanding how to edit each little "piece" to get a certain result

    if you have ever made a counter or a number pad before then this should be easy.

    i havent, i couldnt exactly master this before WIRE so i thought as this is now sort of "fair game" with everyone starting on it at close to same time and WIRE looks much simpler so id just learn now

    EDIT like if some1 could just make one "unit" from the rom and have all the inputs/outputs labeled and label which ones you edit then i should be fine

    lol k.

    lets start with something basic


    spark the PSCN on the blank ROM one by one then spark the PSCN on the ROM with data one by one.try and find out why the ROM with data is different then the blank ROM ;)

    ok i see the "ear" thats deleted to allow it to forward the and i have a bit of a feel for it but if i say wanted to add another row would i just use the small shape with the "ears" seperated by one pixel wherever it touches or are the pixels that seem to space it apart part of the units?

    it's something like this .

    the bottom 2 are inputs and the top 2 are outputs.

    if both ears are intact and you spark the bottom left one then it will go to the top right output but if the left ear is removed it will go to the left and right outputs while the right input will only go to the left output.if both ears are removed then both inputs will exit thru both outputs.

    ok that makes more sense and finally are you able to add another row to the whole rom? i tried it but it had a tendancy to end up powering the entire rom

    EDIT: ah i found the problem i was connecting part of the new row in the wrong place

    thanks for your help tho its greatly appreciated

    yes you can.


    this one has 1 extra input.the one on the far right is a complete one.the outputs can also be expanded

    i can also give you an example of one with extra outputs if you want.

    yea i see how to expand now, it was just a matter of making sure it all lined up correctly

    and heres what i was trying to do with adding another row


    this way you can have a binary output :P
