Martin is working on a PC-->SAM bus interface, but the IDE drive doesn't need that -- in fact, it *may* only need port decoding logic, depending on how many drives stick to the original 8/16 bit switchable standard. If not, it requires a couple of Input/output latches to convert 16bit data to 8... not a great hassle. We're gonna release one at about 80 quid which will have a 512k SAM OS in it, and assemblers, shells, the works. I'd like a UNIX system on it -- any takers? (Don't worry about the C compiler -- we'll sort that out later) It's already got CP/M in the ROM. Si Cooke
