Nice one Stedy..
 I spent ages the other day trying to find  E123&E125 on the top side of the mobo!
 Brain must have been firing on 3 cylinders, as I didn`t think to look underneath !   :crazy:

Well, I did all the fixes on my 2B board tonight..
 A little tip for adding the 470R pull up by the ROMs..
 I found it #@~ing impossible to solder the other end of the resistor to the via on the board.
 I simply used a thin piece of insulated wire, and soldered it to the bottom side of the +5V on the floppy power connector, and then soldered that to the resistor.
 There`s probably a much easier and neater way, but I went for the quick fix !

Edit.. Sorry, I`m speaking outta my arse..I didn`t read Ian`s site properly  :roll:
  Don`t bother doing what I just described, it doesn`t do anything.. as the connection at the cap near the ROM is the +5v...silly me, I thought it was the trace I needed from Alice .
