Dear Joe, Can you give me information about the manual? Where are you? can give me your mail address? Best Regards, Hi, I picked up a couple of blue three ring binders with Perkin Elmer logos on them. Both have manuals in them. One is for PECESS Software Packet for a UV/VIS/NIR Spectroscopy and has some printouts with BASIC listings. The other has a manual for Command Descriptions Reference Manual for CDS-3 Application program. Does anyone want them? I'll trade for something I can use like HP manuals, Tektronix 4041 manuals or ???? Joe.
