1. A customer of ours is just trying to extend the lifetime of a legacy product with a lifetime buy of an obsolete PowerPC processor they use in a module. Turns out they were not the only ones on the hunt and this chip is no more. They were now offered the security-enabled variant where apparently a few hundred are still somewhere on a shelf in some warehouse. Thankfully (hopefully?) it will be a drop-in replacement with no change in hardware or software. Famous last words, I know. “Security-enabled” always raises some back hair with me.

   We bought the T962A years back. First run, it smoked and stunk like hell. Fifth run, the fuse holder got so hot it melted.

   There was no cold junction compensation and there was no ADC front end.

   Although there’s a crystal, the timing was about 20% off to start and would slow down during the profile due to inefficient code. Each run would heat the controller, and would occationally cause the thing to lock up with the heating elements hard ON. Even when it wasn’t locked up, the hot melt would MELT and the LCD would slowly disappear.

   After the thing caught fire, we took it apart and reworked heat shielding, fixed the dangerous wiring and made our own external controller. The damn blower kicked in at the wrong time during one very expensive UVC array build and we stopped using it.

   We took its controller and put it on a $20 toaster oven. Works like a dream.

   If anyone could recommend a REASONABLY priced professional oven with an exhaust vent please tell. We still can’t find a desktop oven for less than $1k. There’s no reason they can’t sell a good one for $500
