This is the list of components and prices (AUD 2013) which was required to update the electronics so the Boxford 125 TCL would run on Mach3 and Windows.
Breakout board C11 $129
Index pulse board C3 $26
Gecko stepper drivers G251 $68 x2
Relays, relay bases, parallel port cable, Estop button ~$80
Power supply $30
Wireless MPG from China Ebay $129
Heat sinks and adhesive $20
Other cables, connectors, power sockets ~$100
PC (an old Dell, running XP Pro, perfectly adequate for Mach 3) free
Flat screen free, wireless keyboard and mouse free.
Support arm for Screen $60
It all adds up to $AUD910. Plus the original $1500 for the lathe. That is pretty inexpensive for a quality CNC lathe. I am told that the Boxford retailed for about $30,000 in 1985!
