I need a device that is capable of "playing" a string of about 40+ DTMF tones. This device must play these tones to a speaker, and be very inexpensive. I've looked at Intel's 8051, but the price is a bit steep at about $5.50 each. Does anybody have a cheaper solution? I hope to find a device for about $1.00 per unit. A 4-bit microprocessor might work. Any help available would be appreciated. Please reply directly to: HTCINK@teleport.com Thanks, CW PS. I am willing to pay a small amount -- ---------- REPLY TO: chris at htcink@teleport.com ----------
