A question re go71

[rprosperi]

I've been thinking about getting go71b for a while; now that there is some discussion among users here, I have a couple questions:

1. Is it correct that that go71b comes with the MATH ROM and FORTH ROM pre-installed, and that they are permanent? There are screens shots showing portions of VER$ results that do not include the FORTH ROM (some do, some don't), but the text (which is definitely incomplete and confusing) seems to imply these modules are somehow installed (along with the HP-IL module) in Port-5.

2. What, if anything, does the HP-IL module allow you to do?

3. Is it correct that one can import/export 71B files between IRAM ports and an Android folder, but those files must have the .LIF header prepended to them (to provide file header details)?

4. There is a comment "show lex-ID and min-max tokens #" - does this simply mean the HELPLEX file is preinstalled?

5. I have a Moto Z Force with 5.5" (diagonal) LCD. Is go71b usable on a screen this small?

And thanks Didier for the detailed walk-through of configuring memory. Having used other emulators of Olivier's it makes sense and I'm sure I would have eventually figured it out, but your steps make it trivial plus I want to add that I too am impressed and wanted to convey thanks for the huge effort to make such a detailed tutorial. Not an easy thing to do on mybb!
