This was a lesson learned in the times of LPT and COM ports, where factory-made peripherals and DIY boards alike had to pull peculiar tricks to get a few milliamps, often tapping data lines.

"We initially hoped that a higher dose at 4 milliamps electrical stimulation had a better effect than a lower dose as well as the sham group, but we did not see that." In the United States ...

Even though the drop down for units showed mA (milliamps) and MA (megaamps), every time we tried for milliamps, it reverted to mega amps. On the plus side, you can group the calculators together ...
