You can register your trial copy of SPCALC, Version 5.0, by returning the order form below along with the registration fee of $39 (U.S. funds, check or money order) (requires an e-mail account that will accept EXE files or ZIP files containing an EXE. An HTTP download can be arranged for those lacking a suitable e-mail account) or obtain SPCALC on diskette or CD-ROM for $39, plus $10 S/H.
