What damage might I do?

    I have a 16c84/f84 programmer (very uncommon make) which works fine. I want to program a 16c71 which looks like it connects the same as the 16c84 except it has 4 channels of ADC that can be programed to use 4 of the I/O pins.
    Am I likely to damage the programmer? I just don't have the courage to give it a go!
    I know the chips are a bit old but I have quite a few of them and I don't want to waste them if they can be used.
    Perhaps someone who knows a lot more than me can set me straight?
    Thanks

    Different programming algorithm. Old PICStart+ programmers could support the ancient OTP 16C71.

    Thanks for the reply.
    Now I see the problem with the 16c71, it's OTP. CLUNG!!
    Ok, only option is to update to the 16F876 or 877 or above. Trying to avoid starting again with programmer, software, PCBs etc, but looks like there is no other practical option. Thanks again, will repost with how-to questions. Guy
