 With Forth we can poke around in all internals using the Forth commands, read and write IOs - even mess up the CPU – so please be careful as you might have to restart the Forth and loose the work done before.
 And this is done using only 2 commands, added especially to this eForth version:
-**PEEK**  -  Read the contents at memory location  xx
+  *PEEK  -  Read the contents at memory location  xx
-**POKE**  -  Overwrite contents at memory location xx with new data yy.
+  *POKE  -  Overwrite contents at memory location xx with new data yy.
 And if you have now licked blood and have the appropriate know-how and tools, you can flash in the extended version of this eForth - but then the bootloader will be overwritten.
