There are 2 programs that I know of, both commercial.  A very simple one is
called "Plasmid".  It can list upto 50 restriction sites and will put them 
where they belong on a circular map.  It will also mark off genes and other
markers, e.g. ori, on this map.  The drawbacks are the limit on number of
sites and that it will only do circular maps.  You must know ahead of time
the exact positions of these sites, and the total size of the plasmid, e.g.
total size 5637 bp; EcoRI at 57, PstI at 135, EcoRI at 457, etc.  Each is
considered a site with a total of 50.  It will use LPT1 only for dotmatrix
printers and can use COM1 for laser graphic printers.  I believe it costs
not more than $50.00.
The second one which does a whole shebang of things, almost everything except
turn itself on and enter the data is from the company DNASTAR Inc.  They are
located at 1228 South Park Street, Madison, WI 53715.  Phone (608)258-7420
Fax (608)258-7439.  They say they can customize their system for anyone.
The whole system costs about $1800.00 but will do all from sequence analysis
of nucleic acids and maps to protein analysis, structure, etc.  Expensive,
and for those who do not have access to mainframe systems that can do this.
It is, I must say, easier than the mainframe programs.
Hope this helps.
Take care.
