Use of RCL pin 21

[shalseth]

First of all, thanks for this project. Looks like it's exactly what I need, and I appreciate the effort.

I have ordered a nwx287 to replace a Dallas DS12887.

I'm unsure about this: "Important: some mainboards seem to use /RCL pin 21, so cut it first if you are sure, that your mainboard doesn't use it."

Is there any safe way I can find out if my main board uses the RCL pin or not?

Any risk not cutting and, and testing first?

The machine is a DEC Venturis 5100, Pentium 100, SIS 5501 chipset.

I'm closing as I guess it is sufficient to check the pins on the original module in question
