Someone should get one, rip out the Z80 and replace it with a Z180 or a compatible successor. Heck, maybe add a Z80000 chip just for funsies, because, why do when you can overdo?
Then rip out the 9938 VDP and replace *that* with a 9978, to get all the latest graphics modes and such.
@vertigo why rip out the VDP when you can already slot in a Sunrise #Graphics9000 or #Tecnobytes #V9990 #Powergraph; both expansion cards based on the #Yamaha #V9978 VDP?
This expandability was one of the beautiful things of the #MSX standards.
Precisely because it's a cartridge. That makes the hardware prone to breakage, and blocks the port from other peripherals you might want to use. The VDP sits at a different I/O location, so system firmware can't talk to it. Etc.
Replacing the VDP internally fixes two of these three issues (and a ROM swap the third).
