This might sound a bit off-topic, but we're looking for a replacement for the SAB 0529 which is a long-term-timer (up to 31.5 h, syncronised to the 50/60 Hz mains), it was made by Siemens until 1992. As there seems to be no direct replacement, we thought of using a PIC for this. So, did anyone ever made such a programmable long-timer with one of the PIC ? Any informations welcome. regards, Reelf Monsees -- BAMBERG & MONSEES GbR Systeme f|r Wissenschaft und Technik Steindamm 22 * D-28719 Bremen Fon +49-421-646775 * Fax +49-421-646785
