Pep is not included in the distribution nor, as far as I know, is
available in any form. Self 4.1.2 does have some "left overs" from the
Pep experiment, however, such as support for 32 bit integers and new

Which paper do you mean? There is Ole Agesen's 1997 one and Mario
Wolczko, Ole Agesen, and David Ungar's 1999 workshop paper:

I would say that Frost was more ambitious in that it was intended
originally to become a commercial product while Pep seems to have
always been viewed as an experiment. Other than that, I would say that
both efforts were very similar.
