8Bit Bamboo Core Inside | Redstone Computer

Here it is, the finest in Panda technologies, the Bamboo Core Redstone Computer.

Ok, so the whole bamboo part is just a play on my name, but this is a fully functioning redstone computer

This project is about 65% Complete.

It processes 8bit data, has 6 bytes of RAM and 32 Bytes of ROM (16 Opcode/16 Operand)


  • 0: N/A
  • 1: NOT
  • 2: OR Constant
  • 3: OR Memory
  • 4: AND Constant
  • 5: AND Memory
  • 6: XOR Constant
  • 7: XOR Memory
  • 8: ADD Constant
  • 9: ADD Memory
  • 10: SUB Constant
  • 11: SUB Memory
  • 12: WRITE Output
  • 13: WRITE Memory
  • 14: LOAD Constant
  • 15: LOAD Memory
  • 16: BRANCH Unconditionally
How it works
Full in-depth breakdown upon completion
Left to complete
  • Link opcode decoder to ALU/Memory/etc
  • Finish Accumulator
  • Implement load to accumulator from memory functionality
  • Build user-interface command centre
  • Write test program

Any feedback greatly appreciated, hopefully shouldn't be long until project is completed.

Love this CPU Panda, looks really good. I'll be keeping an eye out for updates as well. You've got a subscriber :)

Wow man, your doing great, i can't believe how much progress you have made recently, i knew you had potential but glah!

This is a great looking computer ! and its a much more computationally powerful device then your calculator, but it's lack of conditional branching means it's still not Turing complete.

I am already eager for updates; best of luck [url=../../member/thesneezingpanda/][img=avatar]../../forums/download/file.php?avatar=196415_1322772360.png[/img][/url] .

I'll have to do some research into conditional branching, I'm not overly familiar with the concept. I would presume that it acts like a conditional statement in high level languages, jumping if a criteria is met, say the accumulator = 0. I'll have to do some more research, but it's something I'll add

You got it ; )

A single conditional comparison ( acc=0 for example ) IS actually enough to perform any calculation, but it may be very slow for certain ones ( where you might be for example trying to classify a number as being in a set of numbers, eg < 10 )

BTW, i made something your gonna like last night; ill upload it as a project after work.

Again, nice work.

Ok, it'll be an interesting challenge designing the COMPARE function, but it does mean I'm going to have to add a fifth bit to my opcodes to allow for the conditional branching :/

I look forward to this mysterious build :)

Actually, you've left yourself with some options; for example is opcode 0 unavailable or simple unused, if so you cauld use that as a compare function, or you cauld even memory map Your output device, leaving opcode 12 available : )

Love the project, and can't wait for whatever's next !

On nice : ). But I think he's a do-it-yourself kinda Panda...

Description says 75% complete, progress bar says 65%. Pandas are known to be indecisive.
