Any mine reports:
MEM - 22423
VER$ - bbbbbb

I'm also assuming to upgrade I just need to copy the correct file onto a USB thumb drive and boot from it? =)

While it is not quite that simple unfortunately, it would be possible to replace the system ROMs there is a pin on one of the ROM ports that disables the system ROMs. During development of the 75 the operating system ROMs where on an external EPROM board. I have one of these EPROM boards and it does not appear that they used this signal line, as that signal line is not connected. I also have a prototype card set for a 75 and the system ROMs are not populated on it.
