MSX AX-330 with built-in Nintendo hardware ...!!

rare object

you can see a LZ93A13 , this chip is a mapper ASCII use in megarom and for making ESE-SCSI

64MB? you mean 64KB(512Kbit). The EPROMs near the ASCII mapper are indeed 512KB(4Mbit). I assume the sandpapered QFP flat chip is MSX engine, which would mean the sandpapered Philippines chip is the VDP? The 10.7386 XTAL near it is the same as for TMS VDP.

The 26.601712 XTAL on the brown pcb is the same as on official PAL NES. The UMC NES chip is on the backside of the green pcb? Oh and if you have the time, could you dump the roms? =)

The UMC chip not at the backside of the green pcb..it's at the back side of the yellow one(the back is green)...check this pic to see where it is...

I don't know how to dump the roms :o

For the MSX part, you need a tape recorder or, better, a disk drive (with interface), then some tools to make the dumps.

For the NES part, you need a NES expert ... hap ?
