CP/M Firmware

[amazingcobrazil]

I have one of these boards but recently bought another one that is a bit more modern with HDMI output (I was using an adapter). I would like to know if it is possible to convert its firmware to CP/M. Is there any obstacle? If so, what would it be?

Hey there. I'm not too familiar with the HDMI adapter boards so take this with a grain of salt, but to my knowledge the only cards that have the ability to be flashed with a Z80 emulator to run CPM are the ∀2 Analog boards and the clones of it. Those boards have an extra programmable logic chip (PAL) on them to help manage the Apple bus I/O with the Pico's limited GPIOs.
