Grease---wonderful :)  Looks like fun when you get it all ticking over.

My last run-in with Houdaille Strippit was for Great Dane Trailers--they 
had some sort of 8-bit CP/M controller interfaced to the punch via 
RS-232.  They wanted to move to a PC platform and use their current 
software, so I rigged up an emulator with an emulation for the UART they 
were using.  They were happy with the result.

Old CNC iron is a lot of fun.  I've supplied replacement drives for more 
EDM gear than I can remember.  The only problem is that I keep getting 
promises for 'artwork" from these guys and they never get around do it... :(
