Just to be clear - you +know+ for a fact there are DIP switches inside, but you only +surmise+ they are for creating fault conditions? As mentioned, I was thinking either pricey components or possibly some sort of anti-theft device.. opening the door exposes a feature that allows the unit to be tethered to a bench. This is before the days of commodity EEPROM, so it's not like they need to write-protect firmware, resident software, etc. On Wed, Feb 17, 2016 at 5:33 PM, william degnan <[email protected]> wrote: > I've got one too, but please don't contact me about it.
