Have you tried the software? I think its the same software for 1400/presto/CombiNation etc. They have the same screen and program set-up.
Yes, i tried the software and it basically works. The problem is, i can't edit anything because the front plate demands a firmware update first. I did not dare updating the machine for the fear of bricking it

If you start the program for editing the recipes, it says that you are using the software with the wrong machine type, although it seems to work.
I know that there is a specific version of the software for the Prestolino, but had no luck finding it on the internet so far...
