 # Setting up the Electron (experimental!)

 You'll need an Electron with Plus 1 (or equivalent - I'm uing an Acorn
 Plus 1) and Advanced Plus 5 (or equivalent - I'm using the Retro
 Hardware New AP5).
 
-You'll need a Tube USB serial adapter (see above). The adapter
-requires modification: carefully bend up pin 9 of the PLD, so it's
-clear of the socket when plugged in. Note that the modified adapter
-won't work with a second processor. (A future update to the hardware
-will fix all of this stuff...)
+You'll need a Tube USB serial adapter (see above). The PLD needs
+reprogramming with the .jed file here:
+https://gist.github.com/tom-seddon/07d9f2942590899044a161edd5fe891a,
+and please also note the instructions there. (The reprogrammed PLD
+will be fully compatible with BBC B, B+ and Master as well.)
 
-Connect the Tube serial board to the AP5's Tube connector, use the
-jumper to select Comms mode, and connect the device to your PC.
+Once set up, Connect the Tube serial board to the AP5's Tube
