After about one hour span time since surgery room preparation to the few minutes post-surgery set of severe tests at the Intense Care Unit, the HP25C Serial # 1511Axxxxx recovered its full operating capabilities. Unfortunately, donator HP25 (ID not revealed so far) is kept frozen for later replacement as it becomes available.

Thanks to specialist advisors Ellis Easley, David Smith amongst intl. cooperators around the world not mentioned here because of a small lack of information, the offended ROM was identified as being the one at the left side of the ACT chip. A brief report mentions that the removed ROM was also tested at the donator's "guts", which showed the same behavior observed in the HP25C before transplantation: a blank display followed by a complete set of "zeroes" after any key pressed except number keys, [STO], [RCL], [f] or [g] and full operating RAM, registers and program steps. This ROM (1818-0154) is definitely toasted.

Thank you all for your attention and patience... reading this silliness.

It does not surprise me that this medical procedure
had such a favorable outcome,

seeing how such a good surgeon was in charge
of the operation.

... you know, there are so many good eyes looking after us that we must do the best to deserve them...

I am sure I'm not being original in this statement, but I'll take the risk of stealing someone else's lines: "I feel as supported by giants' sholders"! At least it sounds good an d appopriate.

Thank you!

Luiz:

Did you use local or general anesthesia?

Hi, Ernie;

Basic Procedures, form MoHPC Publishing Sparse states that a general anesthesia should be used. I "played by the numbers"... as if there is another way to play in this case!!!!

Cheers.
