As mentioned here is a battery backed up T200 capable REXCPM. Hardware worked right away, set up in M100 mode using the same M100 firmware we use today (with a new CPLD pinout).
You can see the little Li batt. It charges to around 3V. I'll see how many days it holds a charge for. I'll go ahead and install in my CP/M computer so I get some run time on it. To use in a T200, you need to sneak the A15 signal into REXCPM. That's why there is a 4th pin on the pin header, in case anyone was wondering.
