Hello Everyone Recently I desoldered several old PCB's I got around 25 mysterious chips that seem to be manufactured by Texas Instruments. They are labeled 81C285T on what (usually) is the part number line and 210895 on the date line (August, 21, 1995) in a 16 SOIC package. I also got what i apparently a pin for pin compatible chip marked as INB627, 1821-0895, by Motorola? from an identical PCB from another [same model] board. I cannot find a datasheet for either of these chips (yes, google has failed me) and it would be greatly appreciated if someone could send me a link to it also would fall more so under the category of [OT] ? --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
