Well here is my mill. It is a Bridgeport Boss5. It was once an AH-HA retrofit. I replaced the computer and original AH-HA control card with a new computer and Mach3 with a G100. I kept the AH-HA stepper drivers and power supply. One reason I got rid of the HA-HA control was the lack of ethernet, CD drive, USB or anything other than RS232 and crappy floppy drive. It was great 10 years ago, but not anymore. I replaced the Floppy with a USB hub on the pendant. Now I can use a USB camera, a mouse, or a Shuttle pro pendant.
