I added a version that might or might not be more acceptable for NEC.

I have the pcb hanging down so the bottom edge of the pcb is just above the bottom corner of the laptop. That positions the usb cable far enough down that the very end of the molded boot is still below the top edge of the laptop. I don't know if this arrangement is the best, but it was easy to try and see, and doesn't interfere with either the serial or phone ports.

Here's yet another option, instead of a special cable, an adapter that just provides a usb jack, and you use whatever cable you might need.

I've already ordered the parts to try it.

I was worried about needing to figure out some kind of spacers and maybe a 2nd small pcb just to get the usb jack a little further away from the pcb surface to make room for the molding around the male usb plug, but I measured several ordinary usb cables and at least by the numbers they should all all just exactly fit. That dimension is probably part of a standard.

The direction the usb cable exits is good for M100/102/200, And works on a PC-8201/PC-8300 but the usb cable blocks the phone or sio2 port. Pointing the other way is no good because that's the serial port. I could make a version that points the usb cable straight up, which won't actually stick up that far because the pcb can extend down to the base of the machine and the usb plug can start pretty close to the table.

It could point directly away from the laptop but I personally just don't like that because it's always a recipe for breaking plugs from the leverage. But the connectors to do that exist and it would be easy to make.
