Re: PSA to SparcBook 2 Users
Yea I received a Sparcbook 2 and saw this damage knock some SMD components off the entire OTHER SIDE of the board from the leaky cap. Got it going again with cleaning and repair work though. I had a SB3 fail in its power supply module due to shorted tantrums on the output side of the supply which cooked the coil and switching driver chip. Luckily most of these components were available from digikey at the time and I rebuilt that entire supply rail and the system came up OK. -Connor K On 9/22/2020 14:45, null via cctalk wrote: No, this applies only to Tadpole Series 2 and potentially Series 1 machines (although I have not observed the latter) Series 3(/3000) are completely different internally.

Re: PSA to SparcBook 2 Users
Apologies if this is easily found info but is there a good guide on getting into the tadpole systems? I recall my last time felt futile and I read some warnings from folks smarter than me suggesting its easy to break but not properly disassemble.

No, this applies only to Tadpole Series 2 and potentially Series 1 machines (although I have not observed the latter) Series 3(/3000) are completely different internally.

Re: PSA to SparcBook 2 Users
You flush electronics with Indian Pale Ale? Too many TLAs. This isn't a problem on the model of SparcBook you sold me, is it?
