### [DM16L] Collatz explorer

Just a fun program that displays the collatz sequence for any number in Hex, Decimal or Octal modes. Binary mode is not supported.

I tried to use the decoder on the swissmicros help page for the voyager clones, however it appears to be broken, so I can only post the memory dump. If someone can tell me an alternative way to get a code listing, I will edit this post to include it.

LBL C starts displaying the collatz sequence for the number in the X register.
LBL A starts displaying the collatz sequence for all numbers following on from the contents of register 1 and doesn't terminate.
LBL 2 is the even case for generating new Collatz sequence numbers.

The G and C flags are used to indicate the 3X+1 and X/2 cases respectively.
