Is there any reason why the unhenhanced firmware ROM routines (copied
into a single EPROM of the right form factor) wouldn't work in a
platinum iie? I have access to an EPROM burner, which I've used
already to burn a 27c256 with the firmware that the machine came with
+ a copy of the "enhanced debugging monitor" with a switch to toggle
between the two, so I was hoping to repeat that process except with a
copy of the Senrio PROM images if/when they are available. I'd also
need to building an NMI switch as well but that looks pretty doable.
