I need help with placing a value on a Cray YMP/EL8
fully loaded with
complete documentation and software (boxes is over 50 pounds) with it.
If this is for a tax purposes, and this was a donation to your "museum"
you should not be attempting to declaring its value.
This should be done through an independent appraiser, like Sellam, by the donor.
