Custom Overlays

[HP-Collection]

Before publishing the new "HP41 Modulliste" I would like to understand for what these different custom overlays are. They are produces / sold by Michael Fehlhammer but it seems that he can not explain for what modules (versions) they were produced (Thanks Michael for your help, I really enjoy your work and your help). Maybe someone of you can answer this question:

Ram Editor RAMED --> ?
Rom Editor HEXEDIT --> ?
Assembler ( modern version ) --> for which assembler (David Assember, Assembler 3/4 or Focal Assembler)
PowerCL Launcher --> für Power_CL Bank-Switched (CAT2
-POWERCL"4X) ?
PowerCL Launcher (blau) --> PowerCL Extreme (CAT2 -PWRCL EXT) ?
SandMath --> for which versions?
SandMath 2 --> for which versions?
SandMatrix --> for which versions?
HP 41Z Keys --> seems to be clear
Polynomial Calc --> for POLYNOMIAL ROM (-POLYROM /
-ORTHOPOL) ?
3dVectorCalc --> for Vector Analysis ROM (CAT2
_VECTORS 1C) ?

The easiest respond for me would be the CAT2 of the module the overlay is for.
