I recently acquired some incremental rotary encoders when a local
disk srive manufacturer shut down. I have two unused HP 1000 pulses/rev
encoders and one ROD 800 made in germany by "DR JOHANNES HEIDENHAIN".
This is about 6 inches diameter and two deep. I believe it to be a 18000
pulses/rev incremental encoder. I have a calibration note for it too.
Mail me if interested.
Mail to either                        
Printf@cix.compulink.co.uk  Should work.
Printf%cix@ukc.ac.uk        2nd best  
Printf@cix.uucp             last hope.
