IC question and hamfest finds

Hi, Mike Haas came down from jacksonville and we went to the first day of the Orlando hamfest. Mike scored big time! No less than 6 different TRS computers. Several are like new and in their original boxs with all the books. He also bought several other interesting toys! I picked up all five of the original E&L BugBooks. Only on looks like it was ever touched. The others are all in PERFECT condition. I also picked up another HP 3468 digital multimeter with the HP-IL interface. :-) Also several NEW manuals for the HP 85 computer. Also several Tektronix manuals relating to HP-IB programming using the Tektronic 4051 computer. Also found the user's manual for the Tektronix 4662 plotter that I have to go with my 4051. Also found a 1982 Tektronix catalog, you can guess what it shows :-) Other finds include some kind of CPU board with a 1802 Cosmac CPU, a HP 97 manual and a Heathkit 4804 Byte probe. However the most surprising find was five boxs full of Intel 1702 EPROMs. In one box I found several ICs marked "AMD AM9217APC". I can't find a reference to them, does anyone know what they are? Also they say "Proto" below the IC number. Does that mean that these are prototypes? Joe
