I've got the motherboard finished and I'm checking the voltages before I insert the chips and everything's kind of high, but I suppose that's to be expected with no load.
Code:
Should be What I'm reading
--------- ----------------
+5 +11.13
+9 +11.90
-9 -9.71
-16 -18.85
+16 +20.00
The one I'm most concerned about is that 11v reading on the 5v line. How's that ever going to come down to 5v with a 15 ohm resistor across the regulator? Any suggestions before I risk blowing all my chips?
Grant, do you have an unpopulated board laying around that you could check the voltages on?
Thanks
Geoff.
