Hi Jochen and welcome.
AmForth is complaining when you upload ports-standard.frt because it
cannot find the word synonym. This is not a built-in word and so needs
to be uploaded before trying to upload ports-standard.frt
synonym can be found in this file
./common/lib/forth2012/tools/synonym.frt
To use the ADC will require some additional Forth words. Below is a link
in the AmForth documentation (if you have not already found it)
https://amforth.sourceforge.net/TG/recipes/Arduino-Analog.html?highlight=adc
The ADC unit on the ATmega328P, the mcu which powers the UNO, does have
more to offer than is made available in the above words. Whether that is
important to you depends upon what you want to do and your appetite for
reading the datasheet and modifying this set of Forth words.
(Had to add -I /home/user_xyz/.../amforth-6.9/common/lib , without it
did
not find some #require files)
tools/amforth-shell.py --help
amforth-shell.py can use the environment variable AMFORTH_LIB which
helps with this.
Let us know how you get on.
Kind regards,
Tristan

Hi, my name is Jochen,
I've tried to upload ports-standard.frt to my (arduino) uno to access
the
adc.
Did use amforth-6.9 with uno.hex and uno.eep.hex (manually, done before
reading the manual).
