I tried very hard to search for stsplus through many archie searches, and only found one site which carried it. I hope that by making it available on World it will be easier to obtain. 73, Scott, WY1Z =============================================================================== | Scott Ehrlich Internet: wy1z@neu.edu BITNET: wy1z@NUHUB | | Amateur Radio: wy1z AX.25: wy1z@k1ugm.ma.usa.na | |-----------------------------------------------------------------------------| | Maintainer of the Boston Amateur Radio Club hamradio FTP area on | | the World - ftp.std.com pub/hamradio | =============================================================================== -- =============================================================================== | Scott Ehrlich Internet: wy1z@neu.edu BITNET: wy1z@NUHUB | | Amateur Radio: wy1z AX.25: wy1z@k1ugm.ma.usa.na | |-----------------------------------------------------------------------------| | Maintainer of the Boston Amateur Radio Club hamradio FTP area on | | the World - ftp.std.com pub/hamradio | =============================================================================== ------------------------------ End of Ham-Space Digest V94 #37 ******************************
