+====== Disassemblers ======
+  * [[https://www.dropbox.com/s/vskoqoxn3kme4ek/RP2040-das%20uni.f?dl=0|RP2040 disassembler]], compact universal RP2040 disassembler.\\
+Note that the check on CFA's in ''%%skip-cfa%%'' is only correct for ITC code.\\
+For other systems this word need adaptation.\\
+  * [[https://www.dropbox.com/s/0ubyr344j7a1q7k/noForth-T-das.f?dl=0|noForth, resident noForth disassembler]].
+An example of its use, disassemble ''%%DUP%%'', ''%%?DUP%%'' & ''%%DROP%%'' in noForth:
+<code>
+das dup
+EDC:    1F09  sp 4 # subs
+EDE:  ` 600B  tos sp 0 #) str
+EE0:    C804  ip { w } ldm
+EE2:    CA10  w { hop } ldm
+EE4:  F 46A7  pc hop mov
+name ?DUP
+EF8:  + 2B00  tos 0 # cmp
+EFA:    D1EF  -22 to 20000EDC bne
+EFC:    C804  ip { w } ldm
+EFE:    CA10  w { hop } ldm
+F00:  F 46A7  pc hop mov
+name DROP
+F14:    C908  sp { tos } ldm
+F16:    C804  ip { w } ldm
+F18:    CA10  w { hop } ldm
+F1A:  F 46A7  pc hop mov
+</code>
+^Command     ^Example            ^Purpose                              ^
+|''%%DAS%%'' |''%%DAS DUP%%''    |Disassemble from the word ''%%DUP%%''|
+|''%%MDAS%%''|''%%<addr> MDAS%%''|Disassemble from ''%%<addr>%%''      |
+Each time the space bar is hit, a new line is disassembled. When any other key is hit the disassembly stops!
+Note that the noForth version is slightly more advanced. It recognizes a header and prints its name.
