  Argh ... it worked and though it wasn't necessary I crushed it!... Ok
  moaning doesn't help.
  Well, I'm no lazy forum member and did a bit of research and found this
  by jammie.emma explaining how to mount the new vfd display:

  I've added some questions, maybe somebody could answer them so that this
  could be an instruction for other EMAX (II) users.

  [1) I'm an EMAX II Keyboard User. Is there anything different? ....]

  "You need to take out mother board and remove invertor by desoldering it

  you need to remove the front display take out the display they just pull
  of as
  they are not soldered
  you need to remove the slide connectors from the the pcb with a solder
  pump be
  very carefull as the pads are week and to much heat will make them lift

  they are in 2 rows of 7 you can leave the ones for the backlight
  connection as
  there is no connection needed for the back light as there is not one

  now you need to wire in 13 cables missing pin 3 26awg cable

  now solder pin 1 on pcb

  the numbers go

  13 14
  11 12
  09 10
  07 08
  05 06
  03 04
  01 02

  and on the vfd its

  1 2 3 4 5 6 7 8 9 10 11 12 13 14

  so solder pin 1 to pin one on vfd

  then 2 -2
  miss pin 3 -3 as thats the angle and its not used on the vfd as there is
  no
  angle on the vfd is nc any way

  4-4
  5-5
  6-6
  7-7
  8-8
  9-9
  10-10
  11-11
  12-12
  13-13
  14-14

  leave 1 inch slack of cables so that you can move lcd into place easily

  now tape up the soldered holes with insulation tape as vfd is going to
  sit over
  some of them

  place the vfd over 1 set of holes near to the back light

  [Maybe that's is just a language problem. I'm not sure where to place
  it?]

  fit a screw wit hwasher onto vfd from front

  place 1 washer and a nut and clap the screw to the vfd place washer up
  to nut
  place vfd through hole on pcb

  allign so vfd is straight and mark the pcb making sure it does not come
  into
  contact with any traces

  now mark pcb and drill with a hss drill bit

  now fit the scew and washers and nuts to the vfd and place the vfd
  screwws
  through both holes and affixe to pcb replace

  pcb front panel

  fit motherboard

  remove psu and replace all caps so that you are fully servicing the
  machine
  [what are caps and why how serving them (buttons?)]

  are you going to make it scsi compatible if so i do a board exchange
  scsi for
  non scsi board and £100

  also do the slim floppy convertors £17

  if your not confident in doing the work

  i do the vfd labour upgrade for £40

  i do the psu refurb for £40

  and if you have the scsi upgrade already i do the upgrade for £50"

  FINALLY I WOULD BE VERY THANKFUL IF SOMEBODY COULD LIST A WHOLE LIST OF
  PARTS.
  IF SOMEBODY HAD A PHOTO OF THE FINAL RESULT I GUESS IT WOULD SIMPLIFY
  EVERYTHING..

  Thank you very much!!!
