At this adress you can find a programmer for the PIC16C54/55/56/57 the files you need is uppboard.pdf, pic5xv02.zip and upp.zip (schematics). ftp://ftp.unina.it/pub/Other/electronics/ftp.armory.com/PIC/DaveTait/index.html I've built it, but I have only tested to program PIC16C54 with it. I hope this will be some help for you.
