You are missing the coprocessor, which is specific to the wildcard. So far as I know, it is what makes the combo exceptionally rare in the revision 2 combination. Still, keep that card, put it in the safe and revisit the valuation in about ten years, I expect it to be 10 fold value for just the card by 2030.

I found another PC with a Wildcard 88 in it - no coprocessor of course, but It functions pretty well. It looks to have been taken care of VERY well too. What was worth the $46K bucks? the wildcard or the coprocessor in it? By the sounds you made it seem like the 8087-4 was as unique as the wildcard Armygreywolf.

The coprocessor that was originally sold as a companion in the wildcard is specific to it. I believe its called the D8087-3 for the 4mhz revision 1 cards also known as leading edge non-E cards. I found one D8087-3 being sold in the russian federation for 2800 USD in January, but I need the D8087-4 which isnt even in the wiki or cpu world. Its for the Leading Edge E model, which was a wildcard that ran at a little over 7Mhz. Yes there are 8087 and C8087s but neither works in a wildcard 88.
I have bought two leading edge systems since March and unfortunately neither had a 7Mhz revision 2 but ONE had a coprocessor, so now I do have a D8087-3, alas it doesnt work so no sweet Kia Optima for me. Still, it has maybe 2k in value, It's hard to judge and I am wholly unwilling to see what happens to one on ebay.
Because of how the processor was made, essentially a glued on die straight to a fiberglass PCB...it is incredibly susceptible to failure simply by handling as they have aged. It's sad, as this was one of the most unique efforts Intel ever undertook in those days and paved the way for system on chip designs later on.
