I was re reading the RR Craftsman articles using the C/MRI., that relies on "any old windows based boat anchor computer lying around" for doing the sensing and signal/switch operations. Since it takes so long for older system to load up and get going, wondered if there was any newer "almost instant on" windows computer like Raspberries etc so minimize wait times until you can operate trains protypically?
For what its worth I use Custom Signal system that is almost instant on and, while not as versatile or flexible as C/MRI, is ready when I am.
