I do not own any Japanese saws, however, Should be able to manage a rectangular hole, to accommodate a zip drive.

Personally, not a fan of the powermac 6100 or any machine with same form factor.

I have this idea of having a zip disk 7.5.5 /w OT 1.3

and one loaded with MacOS 8.1

Trying to figure out if this is a bad idea…
