And once I get it working I will send you a schematic

What part of the RAM are you having troubles with specifically?

I just cant work out how to successfuly put something into it. Im using the processor with stack version.

You first put a store command onto the stack let's say
0101 - Store something from register A into RAM
Then the next thing we put onto the stack is the location we want to put it into RAM
0100 - Binary for 4

So the processor should place whatever is in register A into ram slot 4.

Thanks I will give it another go in a little while, before when I did it no spark was in the ram so I assumed it didnt work. I read something about two cycles, do i need to leave a gap in the stack? Or by two cycles does it mean 0101 0100?

First you have to put the value into a register.

0001 - Write to register A
0010 - Value to write
0101 - Store register A into memory
0100 - Memory address to be stored into

So it takes a grand total of four lines to store a value into memory. Here's how it would look in the stack:

I realised what I did DOH!

You gave me:
0001
0010
0101
0100

I did
0001
0011
1001 <-- used the wrong code
0001

That would 'splain it!
