Title: Does the PCE bus power out/in pass through the voltage regulator?
Post by: soop on February 22, 2017, 08:45:10 PM

So just wondering if any of the pins on the external bus pass through the 7805 on their way in/out.  I plan on connecting a 12v battery to the power in, and then hopefully getting 5v out to power a cheapo MP3 speaker that usually run on 2 AAs.  I'd guess 5v is probably in range, where 12v could fry the amp.  I'll power the LCD screen from the bus too.

Haven't you found a screwdriver yet?
