Credit for parts of the CRAY RAM goes to Mur. You may copy any part of this save with credit.

Oh my goodness! The first person to write a 3-bit encoded BF interpreter in BF and an accompanying "BF DOS" gets a cookie! That is, if you can write a BF program to edit data based on user input. Also a cake to the first person to write and execute said "BF DOS" from RAM to write programs, using the ROM stored BF DOS, and so on.

@PortalPlay And yes, I believe that should work. I chose to decrement the second operand and increment the first as the result while you did it the other way around. Saves a character. :)

I wrote this addition program, ",>,[-<+>]<" in id:2026042. but it appears that there is a bug where the value stored in subsequent "," value inputs is NOTed with the previous input. E.g. If I input 11 in binary, trying to input 01 will store 10 in the RAM.

If I want to add two numbers, ",>,<[->+<]>." should work, right? Because after getting distracted looking at a whole bunch of esoteric languages and comig back to this, I can't even add two numbers :(

How low [level] can you go? Now someone needs to build an assembler :P

Just clear out the blue FILT inside the ROM and add place new pixels according to the diagram above.
