Is the silkscreen wrong on the power connector?

[derkom]

Is the PWR2 connector on the TF536 labelled backwards?
The pin labelled GND definitely appears to be connected to VCC on the 68k, and +5V is connected to the ground plane on the board.
Possibly this problem was referenced here?

Edit: Text kept for posterity and appropriate levels of embarrassment for myself. Do not pay any attention to this. I was wrong. Silkscreen is correct.

Very probably.

Dont trust my silkscreens.

Silkscreen is fine. I program the CPLDs with that polarity, so it must be correct.

The power labels on the 536 rev2b are correct, TF fixed this on an earlier revision. The image is deceiving as +5V looks like it is surrounded by GND but is actually connected to an internal power layer. The +5V on the 68K is connected to GND via a decoupling/smoothing capacitor, not directly.

Oh gosh, this is why I shouldn't work too late at night. Of course that is a decoupling cap, and for some reason I just didn't realise it last night.

Apologies to all. Nobody listen to this thread and accidentally hook it up backwards.

No worries there Pal, there isn't one of us that hasn't popped a board with the wrong polarity
