Ouch! Yeah, I used that version back in the day as well, but then came an update or two of Plover, which required a higher version of the Mac OS than I had installed at the time, so I fixed that, updated Plover to 3.X, and now I am happily using version 4.X.
Of course, I kinda miss that green P from back in the day, shown here in a still from Shabba Ranks' "Mr. Lover Man" video ....
