Sorry; I didn't realize anybody was working on this.

Interestingly enough, I cannot find a Vrc4172 in my MP 800.  Could it
be a different chip?  On the CPU daughterboard which has the Vr4121
(or D30121F1), there's another chip which is labelled "D82310S 1003
9915KU250".  I think a Vrc4172 would be labelled D31172.

Where can I find an explanation of these labels?  Google didn't help.
