Graham, Parallax software has always been available for free download - first on the BBS and now via ftp. You are welcome to download the Parallax SX-Key software (includes editor, assembler) if it suits your needs. My understanding is that Ben's programmer software will read the Parallax file format with embedded fuse data. ftp://ftp.parallaxinc.com/pub/parallax/sxkey_v1_02.exe (296K) ftp://ftp.parallaxinc.com/pub/acrobat/sx-key_manual_v1_0.pdf (2.1M) sx tech support mailto:sxtech@parallaxinc.com Regards, Russ -------------------------------------------------------------------------- Russ Miller mailto:rmiller@parallaxinc.com Parallax, Inc.
