Some time ago I told you, that we're not dead yet, but.. that's not entirely true. Long story short - I was sniffing the GPIOs with a logic analyzer to see how the new code works and suddenly I have shorted out mains to the chassis. Boom, flash, circuit breaker engaged, but it was too late. Logic analyzer is partially vaporized, my laptop doesn't start anymore (at least my hard drive seems to be intact) and the logic board of DW6k is dead as well... I don't know yet if the analog boards are fine, but first I will try to fix the digital one (mostly off the shelf low cost chips) and try to estimate the damage. upd7810 is fried, no clue about other logic chips. Fail of the week, huh?
