TF1260 Enable060 jumper function?

[T'PAU]

Hi,
I just purchased an Amiga 1200 including a TF1260 with LC060 CPU.
It also has a CF card with an already installed 3.1 system, so I can just dig around a bit and "learn" things, usage etc.
There's a program which activates/deactivates Fast-RAM when needed, ok.

I haven't found infos so far, on what exactly the jumper "Enable060" is for?
Is it what I think it is, to switch between TF 060 and Amiga 020 CPUs and still be able to use Fast-RAM in 020 mode?

I'm new (again, got an A500 from '89 to '93) in the Amiga world and have to figure out things step by step. ;)

A "midrange" goal will be to build up a new 3.1 (maybe later a 3.2) system from scratch on a CF or SD card with WinUAE.
Is there anything I should be aware of while installing, concerning the TF1260, to make this CF card work on my 1200 with TF?

I already found the "TF1260 Info and Installation Tips" from alenppc, which already has some useful informations!

If you remove the jumper then the TF1260 is 'disabled', I.E it is not seen by the A1200 and reverts back to a Standard A1200

Ah, ok. So the complete TF1260 incl. Fast-RAM is disabled then?

Would have been nice to compare WHDLoad games (which needs additional Fast-RAM afaik) with 020 and 060. :)
