Coldfire M5485CFE/BFE: $360/$310
Custom design I/O interface: ~$1000 ??
COTSEvaluation Board
M5475EVB/M5485EVB (2 PCI): $850
M5474LITE/M5484LITE (1 PCI): $299
PCI Card (COTS/Custom): ~$1000 ??
Cisco switch: ~$200
Timing (~20 power supplies need timing)Timing on micro IOC: ~$1000 ??
Timing in VME: ~$17000/20=~$850
So Cost = Base+~$2800+optional timing
Need Ethernet cable, optional timing cable
Have to develop BSP, external regulation and EPICS support
