Re: The big red button
I once had an "internal" UPS on ISA bus with a lead-acid battery (industry standard by then) stuck inside the mid-tower PC case and secured with 2-sided adhesive tape... It ran flawlessly for almost 6 years until the electrolyte dried a few weeks before a power outage... And it had almost no monitoring capabilities (more than 20 years ago)... That piece got to rest a while in a "spare" equipment for 2 more years before some beancounter decided that the residual value was NIL.
