When they offered to upgrade the firmware for free, I could not part with it during the school year, so by the time summer came around the free firmware upgrade offer had expired and I had to pay an additional $135.00 to have the firmware upgraded getting rid of the exp(ln(2.02)) bug. So the total cost was about $535.00

Mine still has that bug.

With so many of them having had the firmware update back in the early '70s, I wonder if the existence of that bug in a 35 nowadays actually adds to its value?

Absolutely YES!

It isn't logical that a known-defective machine is better, and arguably can be defended as these are theoretically more rare than fixed ones, but it makes perfect sense that they're worth more to an HP collector as this little bug embodies so much of what makes these machines so treasured: vintage, algorithms, candidate for a free bug fix from HP, etc. I still want one to augment my other 35 that does not have the bug...
