There is a similar program which runs on a PC called OligoMutantMaker.
It is available by anonymous ftp from:
Host fly.bio.indiana.edu
Location: /molbio/ibmpc
FILE -rw-r--r-- 8540 May 14 1991 oligo.doc

I am including some information about the program below.
Happy New Year,

INTRODUCTION
OligoMutantMaker simplifies the designing and screening of
oligonucleotide-directed single amino acid substitution experiments by
searching for nucleotide sequences which introduce a restriction
endonuclease recognition sequence into the codon substitution site of the
mutant.
The program utilizes the redundancy of the genetic code to generate all
possible nucleotide sequences for a given amino acid substitution
(including nucleotide sequences in which silent mutations are introduced
into the 5' and/or 3' codons immediately adjacent to the substitution site)
and determines whether any restriction endonuclease recognition
sequences are present. Any nucleotide sequence containing a restriction
site is displayed/printed along with relevant information about the site
such as its restriction enzyme(s), the random frequency of the enzyme's
recognition sequence(s), the prototype of the enzyme, isoschizomers of the
enzyme, and the unit cost of the enzyme from various biochemical
suppliers.

ADDITIONAL INFORMATION ABOUT THE PROGRAM
Restriction Site Location:
OligoMutantMaker searches for restriction sequences which have at
least one nucleotide in codon #0 (i.e. the codon to be substituted). Since
the longest recognition sequence (GGCCNNNNNGGCC--Sfl I) spans thirteen
nucleotides, it is necessary to enter 27 nucleotides (twelve nucleotides on
either side of the three nucleotides which comprise codon #0) into the
program in order for it to function.
"Silent" Mutations:
The program utilizes the redundancy of the genetic code to generate
all possible nucleotide sequences for the given amino acid substitution in
codon #0 (i.e. the codon to be substituted). In addition to searching for
restriction sites which match these nucleotides sequences, the program
also examines those nucleotide sequences in which "silent" mutations have
been introduced into codon #-1 and codon #+1 (i.e. the codons immediately
upstream--or 5'--and downstream--or 3'--from codon #0, respectively)
and determines whether any additional restriction sites are created. Only
those "silent" mutations which can be created by a single substitution in
the nucleotide closest to codon #0 (i.e. the third--or "wobble"--nucleotide
of codon #-1 and the first nucleotide of codon #+1) are examined.
Therefore, only five nucleotides (centered upon the middle nucleotide of
codon #0) are subject to substitution.

Miscellaneous Notes:
OligoMutantMaker recognizes 164 different restriction sites which are
are cleaved by 126 different restriction enzymes.
Price comparisons are based upon the smallest low concentration order
available from each supplier.
OligoMutantMaker does not search for cleavage specificities generated
by methylating DNA with a selected restriction endonuclease (see NEB
1986/87 Catalog p32 & p123 for further details).
OligoMutantMaker does not note enzyme specificities resulting from
star activity (NEB 1986/87 Catalog p86 & p121).
