Hi, I have just got half a dozen sab 8052's pulled from old equip(ex bbc videocrypt units) and probably are programmed, as I cannot seem to get any data from siemens on these can anyone help? please excuse this post for sounding a little lame but I am pretty new to this subject. Am I right in thinking that if pin 31 of these chips is taken high or low that I may be able to control this chip and bypass any internal programming and use an external eprom? much the same as 8031/32's? it would be a shame to chuck these if they can be used, any help would be greatly appreciated.

Steve.
