No, fortunately not. The LA30 was notorious for having a very bad and very
unreliable keyboard. Some GT40s had that same keyboard as well, I don't
remember if that changed later. The keycap shapes were different too: larger
and more square with sharper corners.
I don't remember the VT05 well enough, it may have been like the LA30 or
different yet again.
The VT52 keyboard technology shows up in other VT variants of the same family:
VT55, VT61/t, VT62. It is also used in the LA36. Similarly, VT100 style
keyboards show up in other devices of that era: Gigi for example. And the
LA120 may use that generation of switches, I don't remember anymore.
