Canon V-30F MSX2

Is the slot layout of this model already confirmed and are the ROMs dumped?

I will dump the roms, all three roms are in socket.

In this proto, in front panel, the text says "Home computer" (vs. "Personal computer" in production)

In Fdd frontpanel there are no drive id, and dust cover is black (vs white in production)

Inside computer, for backside cartridge slot, the plastic cover over the pcb is white( vs. black in production)

All three roms are now dumped, and can be found from:

also VRAM expansion board kicad files are there, but it is "proto" for this proto....I have ordered non-golded pcbs.

By the way, in these rom ics, there are hand written texts straight to the chip surface. In disk rom there is text "V2.0" and in sub rom, text "MSX 2". In main rom there is no visible text.

@gdx: these pictures come from the released machine.
