    4kb = 4000 bits. 4000 bits / 29 = 140. sqrt(140) ~ 12. A 12x12px FILT block has 4kb capacity.

    a 10px X 10px filt-aray ROM can store 100 bits!

    It's a ROM. You can't.

    How to write to it?

    That one was actually only intended to reset the line counter in order to easily write in the new adress, but I guess what you found there could also be pretty useful to know. I never even considered it when building this. Thanks for pointing it out!

    In addition to the labels: The topmost address line is actually some sort of latch that when sparked for the first time enables address override and disables it on the second spark.

    Ah, so this is actually a ROM. It's also optimised for fetching instructions, with the address being automatically incremented with each fetch. Awesome.
