They have IBM-PC compatible slots. Since it would be Unix rather than MS-DOS, one would need to write a Unix device driver to support I/O to/from the board(s) in the multi-tasking environment. (If anybody has done that for the Apollo I'd like to hear about it!) In that context it would help a lot if the transputer board would support interrupts and DMA. As far as I know, Microway and Definicon do not, but the CSA boards do. The Inmos B008 does, but the B004 does not. I'm not sure about Parsytec. Any others? - Moshe Braner PS: I do hope Niche is revived!
