Computerizing the Unimat

Dear Friends....Would anybody care to share their thoughts, ideas or
experiences on converting my small Unimat SL 1000 to a Computer
Controlled Machine? Have been considering setting this up in the Mill
format to basically reproduce different fonts in plastic, or soft
metals, one letter at a time if necessary, to be used on a manual,
motorized engraving pantograph. This is all quite new to me. I don't
have much to share except questions to ask? Information on hardware,
motor, configurations or software sources & ideas would be greatly
appreciated at this time. Thank you all for taking the time to ponder
this & your patience & understanding. Pete
