A few weeks ago, I told you that the Dutch magazine 'Elektuur' (which also has numerous editions in other languages) had announced the publication of a DIY phone switch project. This is just to tell you that I have just received my copy of the september issue of the dutch edition, and it does *not* contain this project. No need to try to find it... Background note: it has already happened in the past that announced projects have been delayed. They usually appear some day (this magazine has published some very sophisticated projects). /AF

I have just received the October issue of the magazine 'Elektuur' (Dutch edition). It does contain the promised project. I have not seen any other edition yet, so I can't say anything about publication in other languages. A long description would probably ruin this already overcrowded list. I'll just tell you that there are two boards: a generic analog interface and switching board, and a microcomputer board based on the 8052-AH-BASIC processor. Eight extensions, one 'foreign network' port. Software written in BASIC, modifiable by hooking a terminal to the microcontroller. Obvious weaknesses: no DTMF decoder (yet, it could certainly be added - maybe a future project); no dial tone generator (but busy is implemented). AF
