The = schematic on the CTS256A-AL2 (the text-to-speech controller chip) showes = an optional TMS4016, a 2K x 8 SRAM, used to expand the buffer between = the 2 chips. Does anyone know where I might find a pinout, or better = yet, a datasheet for it? A search on Google yielded nothing useful. I = have a couple of HM6116's and was wondering if I could substitute one of = them? =20 Thanks, Duane -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
