Hi The chip is a "CML" chip and they are on the web , you may need to fill out a short question or two then download. You may also use an older chip(obselete but used equip will have) being the fx315 which is very easy to impliment and is run by a 1 meg chrystal.binary method of programming-very easy. Good luck( I feel sorry for the OM who takes over my repeaters when the time comes-he will be scratching his head for a VERY VERY long time.)
