If you recived a Fully Assembled BlueSCSI after April 1st, 2021 then this was done for you. If you have a kit labled 1.0-b you can make these modifications to become a 1.0-c.## Steps### Disconnect `TERMPOWER` from 220 Pull Up JupmerUse a cutting tool to cut the small trace between the `TERMPOWR` and 220 Pull Up Jumper pictured below.Make sure continiutiy from `TERMPOWER` to the diode still flows correctly but is disconnected from the jumper.image::images/1.0-b-bodge-1.jpg[]### Connect 5V to 220 Pull Up JupmerNow we will provide pull up from the 5v provided by the BluePill.image::images/1.0-b-bodge-2.png[]### Complete!Thats it! 5v to the Pull Up resistors will now work when powered externally.
