Once around a parsec

I've no need for the numerical pad on my AT keyboard, so how to remove it?
This is plan:

• redesign the case
  I want to keep the nice design on the side, so i made a hole in the middle, indeed, take a look to pics or it didn't happen!
  result is a case without numerical pads, and without the leds! done
  drew some hole for leds, and audio jack/spk switch
• make 1 part circuitry, multiple parts
  So, Goupil(Cherry in fact) has made a looong pcb that contain all, on the side i remove, there's the CPU & ROM, Quartz that interpret all of this.
  No contact is open contact!, so it is for a cut
  I'll have to solder cables between all parts missing from absent keypad. Huge job to list and draw all necessary connections! but done! and re-checking twice..
  
• making the keyboard beep!
  As there is no numerical pads, the VerrNum led doesn't do anything usefull,
  solder across it a jack, or directly a speaker inside case with a switch
• so was VerrNum
  well, VerrNum is missing too of course, and it could be use for 1-bus input, so jack it into stereo with its' led
• making it usb!, and hub, and power hub!(1A!?!)
  We'll see..
• ZX spectrum mode
  for zx mode, a simple hijack on the 4*8 connectors of the zx spectrum, and through a PIC/etc do simple onwire conversion, the whole being activated by a switch. Kinda need some stabylo for the keys makeup!
