/* Technical */
We can know more about this hardware.
 
The hardware only has RAM and not ROM, therefore the device needs software programmed into the RAM to use it.
 
== Technical ==
 
* Has a write only I/O port &FBFB/&FAFB (partially decoded. A10=0, A2=0). A8 controls ROMDIS/RAMDIS signal. Cleared by RESET.
* Freeze button seems to trigger normal interrupt (not NMI?)
* Seems like there is rom and ram access.
* The unit has a switch for load/save, looks like A12 is driven depending on that.
