Hi,
I have bought a Genitizer GT-906 drawing tablet at a garage sell. The working area is 9" x 6" and it is attached to the serial port. It works good for me using the driver software "FormAldiHyd".
It is very usefull for DPaint for example but it has no sensor how hard you press the pen to the surface.
Unfortunately the minium requirements for FormAldiHyd are a 68020 and Kickstart 3.x so it may be a problem to use this with an A1000.
