Then 'moo-lah' ever forth shall it be. LOL!
"Zorkmid(s)" has always been a monetary reference to the original PC DOS game of "Zork" . . . .
(A testament of my age.)
I am not involved in this 'Zorkmid' pedal venture.
Your DC jack is properly wired, but the input jack is not a TRS or switching type. To prevent the battery from draining when the pedal is not in use, the typical method is to wire in a TRS or switching jack for the input in such a manner so that when there is no plug inserted into the input...
For directly transferring the BIN/HEX patch files to a 24LC32A EEPROM, I've found the easiest is to get an EZP2019 SPI Programmer from eBay or Amazon. Some reading on how to use it is required. There is also a lot of info in the PedalPCB WIKI for FV-1 stuff. This does NOT address the use of DA's...
To "negate the reading means to simply put a negative sign/symbol in front to it. Most NPN JFETs have a negative Vgs(Off) value.
TBH, I've never bothered with IDss values -unless they are outside of spec for the specific JFET.
