You are getting a cold restart for sure. That is the result. What causes a cold restart? Memory corruption, specific bytes in upper ram. When the computer does a restart from instruction 0000, it will eventually look at a specific byte to decide.. warm reboot or cold reboot? So something is causing the machine to reboot and when it does, it is a cold reboot. What software is in use? TELCOM? TSDOS? If you could describe a sequence of failure that would help. > > On Monday, February 6, 2023, Cedric Amand <[email protected]> wrote: I'm really not convinced my problem is REX related, at least not yet Is there a process, a type of crash, or something known to basically crash > the Model T and wipe it's RAM (and reset the clock !) ?
