Re: [CAD_CAM_EDM_DRO] EMC Encoders

There are boards out there with ISA slots
I just bought a Soyo Socket 7 board from
Tiger Direct for about $69.00 and
an AMD 450 I got off ebay for $23.00
The board has 3 ISA slots, baby AT size.
EMC BDI loaded up fine with this board.

32meg memory - (had it laying around)
Vodoo3 1000 video board (found that on an airplane)
old 486 case, power supply, 1.6 gig hard drive, 4X CD ($8.00 Surplus)
14" SVGA monitor ($8.00 from the rescue mission store)
CPU Fan ($6.00 tiger direct)
EMC BDI ($10.00)

Total Cost less than $150.00 for a controller
that does 300ipm rapids Not too bad :)
