- This is the unabridged discription to on how to make your keyboard
- for your Amiga 500 detachable (like it's 1000, 2x00, and 3000 cousins)
-
- What upsets me the most is the fact that is is so easy to disconnect the
- keyboard, it probably would have taken about 1 hour of designing, and
- only the cost of the keyboard case (probably about $1 a machine) to
- make the 500 with a detachable keyboard...
-
- What you will need (this is going to be a fairly lengthy discription, sorry
- about the bandwidth...)
-
- a Torx Screwdriver size 10 (The ones used to adjust the car's headlights
- are too big (size 15 and 20)
-
- Phillips screwdriver (Preferablly size #2)
-
- Wire splicing equipment (electrical tape, solding iron, whatever you
- usually use to splice wires...) You will have to do about 8-9
- of them
-
- A 2x00 or 3000 keyboard case, find someone who had a keyboard go bad and
- buy the case off of them, check at your local users groups or
- talk to a C= dealer and see if anyone ordered a replacement
- recently (Heck the C= may even have one you can buy), about
- $10 is a fair price I think... You can fake it with a IBM
- case, but, you are going to be doing some SERIOUS cutting to make
- it work. You might also try and call up C= directly and not
- take 'No' for an answer, ask to talk to their boss...
-
- A drill with a small bits... This is only if you want to have the power
- and drive light in the 2x00 or 3000 keyboard case...
-
- And Also a wire (preferablly coily to give it that detachable keboard
- look) with at least 8 (nine would be nice though) seperate
- wires in it, get it how ever far you want to "detach" your
- keyboard (within reason)
-
- You are also going to have to figure out some place for the Keboard wire
- to come out of... either through the hole in your case you are about to
- create or out a corner of ther case (that you will have to cut out)
-
- Disconnect everything from the computer, and turn it over
-
- Take the Torx (size 10) screwdriver and remove the six screws on the bottom
- of the case, and turn it right side up, and remove the top... Mine was
- _EXTREMELY_ dusty on the inside, spend a bit clearing it out (to be nice to
- your machine)
-
- The keyboard is EXACTLY the same as the one in the 2x00 series, matter of
- fact the 2x00 series even has the holes for the power and drive lights
-
- It is connect by two things, one a bundle of 8 wires, grasp the wires
- about 2-3 inches above the metal shielding and gently pull straight
- up, with a little but of left and right "rocking" and it will come
- right out, and then dissconnet the uninsulated ground wire from the disk
- drive with the phillips screwdriver. If you don't care about the Drive
- and power light, remove these from the keyboard, and cut the 7 and the
- 8 wire on the connector (to the motherboard), and also disregard the
- comments about cutting drive and power light holes in the keyboard case.
-
- Voila! Your keyboard is now free. If you have got a working 2x00 keyboard,
- and just want to use it, then dispose of your 500 keyboard (note, you
- won't have the drive and power light). and hook up the 1-6 wires
- accordingly to the connector by splicing, and put the case back on and
- your done.
-
- Before you splice any wires, make sure you have the proper wire(s) with
- a Ohm meter...
-
- If you are going to use the 500 keyboard, you are going to have to open up
- the 2x00 case and cut out two "prongs" that stick out, one by the keypad
- hole, and one by the Left Alt key. Then cut out the holes for the Drive
- and power light by matching up the holes from the top of your 500 case
- to the top of the keyboard case and drilling and filing.
-
- Then splice the wires together on the keyboard end (first match the
- appropriate wire on the connector to the motherboard to the keyboard
- cable you bought (with the eight or nine seperate wires in it), and
- then "splice" the other end to the connector, here is where the problem
- arises. If you don't want to mess with the big unisulated wire, then
- cut it off or solder it off or something, if you feel as if it is there
- for a reason (for what I'm not sure, because the 2x00 does not have one,
- and your keyboard for the 500 already has a ground. I suppose if is to
- get rid of any static charge that may build up, but, the keyboard case is
- all plastic anyway...), then splice it into the "ninth" wire and hook up
- the other end to the original ground location on the disk drive. I don't
- see any real problem with not having this wire hooked up, mine works fine
- without it... but, I suppose it is there for SOMETHING. What, I don't know.
-
- After that, plug in the connector and test it out to see if it works, if
- it does, tape the wires down or something so that if you move or pull on the
- keyboard, it is not pulling directly on the connector to the motherboard.
- If not, check to see if you plugged it properly to the motherboard.
-
- Put the case back on the 500 and you are done. There is still the problem
- about the hole in the "face" of your 500, I am going to put a plastic
- sheet back there sooner or later, but for now, I am just going to put
- some velcro on the back of the keyboard and stick it over the hole when
- I am not using it. (the keyboard that is)
-
- Email me any questions, or post them on the net...
-
- For my next trick, I will turn this ordinary cockroach into a soldier for
- Saddam...
