The Firmware Verison is actually important to this discussion. There have been many firmware versions over the lifetime of the Orion. Version 1.x and 2.x have major differences. Version 3.x merged the firmware from the Orion and the Orion 2 into a common set of code. However, the Orion and Orion 2 still have their individual firmware files, and hence the slight differences in the firmware versions.

The Orion Programmer's reference manual was not always kept current with the firmware versions, so its information may not be valid for the version under consideration.

What is the firmware version installed in the Orion in this discussion? The firmware version is displayed at startup, and also by Pressing and Holding the MENU key.

In the discussion, it was stated that if the Orion was powered down and then immediately powered back up, it would still work. This is a big clue that suggests that the internal battery for the Battery Backed SRAM may have failed. There is enough bypass caps to support the Battery Backed SRAM for a short period of time even if the internal battery has failed.
