Pleae don't get too excited. Yet.
Yes there is a prototype.
Yes the onboard memories work, so there's 512k ram and paged roms where the contolling software can go.
And there's a VGA test card display based on the 80 column board and a pre-loaded image.
At the moment that's all there is. The current focus is on getting reliable signals from the 5v 4mhz Z80 to and from the 3v 50mhz FPGA without damaging it. Having the VGA display is nice, but having it programmable would be nicer
Test builds of Andy's VHDL code for the VDP sugguest there should be no problems space wise fitting it into the FPGA we're using.
Other that that, I've not really looked at the SD card or the VDP or anything else yet. (being vague there so there's no premature disclosure of the super secret extras in case they never make it).
It a promising start, but only a start. Hence Dave's warnings about maybe Q3 or maybe never !
