Does anyone know how to get or make a keyboard adapter that will fit a A1200 tower?
I do know that a few commercial versions are available but hard to find and very costly.
I would be very thankful for any help!

Since you have a tower, you can simply use external Amiga keyboard and connect pins 13 and 14 of the keyboard MPU to corresponding connections on the keyboard connector. You also must get 5V and GND from somewhere (I used PSU molex connector). The keyboard reset won't work so you can solder a header to pins 10 & 9 of TP1 on the motherboard and use the reset switch of the case.

Sounds simple enough for you can you draw picture or a schematic.
If you know of a site that has this schematic please let me know.
I'm not sure of the pin numbers on keyboard connector and on mobo connector. Need to do some research before I dive in!
I do appreciate your help and THANK YOU!

@Ellis: Please check out http://mysite.verizon.net/jartz/amiga/kbd_conn.html
As for reset, just locate test point labeled TP1 on the lower left of the motherboard. The two leftmost pads are ground and reset respectively so simply solder a 2-pin header on those and connect your case reset switch to the header.
You might want to use a 44-pin PLCC socket for the keyboard MPU so you do not have to do any direct soldering on the chip.
