If the indexers were well written I wouldn't even notice they were running, but I've seen several of these things come and go over the years and they're always lousy.
Fun fact: if you have an espresso machine with a PID controller that does RS-485 and connect that to a USB serial adapter, you can hook your espresso machine up to Typica. That's a lousy idea as a full time thing but it's nice to have as an option during the initial controller tuning since factory recommended settings tend to be garbage and if you know what you're doing you can get better results than your controller's auto-tune features.
I should probably pull the PID controllers and USB adapters out before the old machines are hauled away. Neither was original to the machine and I can always use more test hardware.
I haven't measured the ground color but the default pre-programmed roasting plan it comes with gets the coffee to a 58 exterior on the gourmet scale which is right on the standard sample roasting spec. I'll need to mess around with this to get something a little closer on the timing to my standard and I'd like to also see about matching my standard for evaluating the potential of a coffee sample for espresso preparation among other things.
