No problem.
Seems that you're about to get it back to business in less than 148 days.

I replaced the HC148 and... everything started working again! I would like to find a way to repay you for your patience, competence and availability: how can I do it, Mark?
m k:

You had stamina to go through it, so now the collective can learn and hope that next case is easier.

E,
