The front bottom left corner of the 88780 is visible through a hole in the box, and is visibly mangled. I'll take more photos as I unbox it tonight. Based on the service manual, it appears that option 800 requires: * buffer PCA 07980-6xx14 (512K) or 07980-6xx34 (1M) * read/write/formatter PCA 07980-6xx31 Were there any other hardware changes for option 800? If not, one wonders why HP documentation is adamant that it cannot be field-upgraded to option 800.
