Hi All ,I Have a Maximus programmer v 1.04 which I bought a few years ago from Mrpcb. I need to replace the 16 pin Ic - but the numbers have been erased from the chip. Does anyone know what this Ic is,or where a schematic diagram can be obtained? Many thanks
Thanks for the updated info regarding the 4049ube. Could you tell me where you got yours as I have tried locally and also a few of my suppliers ,none of them have the ube version only the standard buffered 4049
The UBE spec may not be crucial, it was just what I found in my cmos/ttl chip collection, probably from Farnell/CPC or RS components. The main thing is that it makes a reliable oscillator using the ceramic resonators of 6 and 3.58 MHz, if you use a socket it won't hurt to try any of the 4049's available.
