The product is Hijaak, (c) 1987 by Inset Systems, Inc. It converts among
several graphics file formats including IFF, TIFF, PICT and others (about 10 in
all, I believe). I do not have the address or phone number (they're at work),
but will let you know later in the week if you wish. (Inset is someplace in New
England.)
