hello,

we have got old 8031 based card. As availability of 8031 is a problem we need to replace 8031 with upward compatible 8032.
the difference between two is we get extra timer, interrupt & 128 bytes extra RAM.

Will it be ok if I blindly replace of chip 8031 with 8032 ???? With out looking into olddddddd software and testing.

What about 89c51 & 89c52 ?? As we are using these chips for our new development.

have a fun & enjoy
