I used these two chips to build an RS-232 speech synthesizer for a school project a few years back, and was reasoanably pleased with the results. I recall using a 3.58MHz color-burst crystal rather than the 3.12MHz one specified, and it worked fine. And while I used the recommended 10MHz crystal, I believe it just sets the speed on the controller chip and should work at a nearby frequency such as 8MHz (not guaranteed, just a guess). When it worked, it worked well. Creative spelling often allowed it to pronounce almost any word correctly. Unfortunately it badly slurred r's as I recall (ie, "three" came out as "thlwee") but this is so obviously wrong that I'm sure I damaged the chip slightly during handling (since I never bother with any precautions). I intended to do more with it, such as programming my own EPROM, but somehow just never got around to it.... ______________________________________________________________________________ ___ , , ,;,;;;, / Y /| /| Charles Flaig ;/@-@\; | |/ __, ,__ |/ flaig@csvax.caltech.edu | ^ | | /^\ / | | | / /\ /\ \=/ \____/| \_/|_/\_/ \_/ \_\/_/_/_/ "What, you think they PAY me for this?"
