- A/D, D/A, and digital I/O capabilities. However, the last time I checked they
- had little explicit support for the SGI. We ended up memory-mapping the board
- (their model DT1492G-8DI, 16 bit DIO, 8 channels of differential 12-bit A/D
- @ 250 KHz total, 2 channels of 12-bit D/A @ 130 KHz/channel) into user
- memory space (both registers and memory buffers) and writing our own
- user-level drivers. An SGI support guy gave us the base driver for the
- board from which we developed our drivers, but I'm not sure if I can still
- locate him. I do have the original driver he gave us, though.
- The general company info is:
