Interesting sighting on Geekhack:
"I was expecting SKCM "ivory" switches (earliest tactile SKCM switches, about the same stiffness as salmon switches), as that's what the ~1986â1987 versions of these typewriters had, but this version turns out to have plate-mounted Alps plate spring switches throughout the main section, with double-acting plate spring switches on the spacebar, return, and back space keys, and a mix of SKCL green and double-acting SKCL switches on the lock key and on the side function keys.
That explains why the later typewriters used a mix of SKCM and double-acting plate spring switches. I assume the switch from plate spring to SKCM was for cost cutting, but maybe someone at Canon or Alps just preferred them.
Keycaps are spherical, mostly doubleshot, with pad printed legends on all the window keys (except the lock key). They were originally white on gray, but now are yellow on brown."
