I hope you will mirror these two files to iBiblio under
a new p4/ subdir. Historically, it's very interesting
(although obviously P5 is better). I mean, Pemberton's
whole book about P4 is still hosted on his website! (This
old code is explicitly "public domain".)

Note that I kept .EXEs in a separate .ZIP since antiviruses
are overly zealous (esp. for Windows). There are several
reasons for also having a Win32.EXE. I wanted to prove
it works on something other than DOS/DJGPP/GCC. I also
wanted something that will still run under ubiquitous Win64
systems. I also wanted something that will successfully run
in DOS under Japheth's HX or if stubbed (stubit) via WDOSX.
