- Hopefully, source we _will_ have soon. If Russell sends me the disk then
- I can put up on an ftp site for other people to download.

- I think it ought to be well within the capabilities of somebody who knows
- a reasonable amount about the ARM family, has the hardware, and has some
- experience of the kernel.

- Yes; I have a SyQuest drive in my (Internet-connected) machine.

- Not even much of that. As things stand, the screen mode is set up by RISC
- OS and left alone by Linux. It would be nice to have a way to change it,
- but it's not vital.

- Basically yes. There are things like alignment errors that will need to
- be fixed up -- as far as I know, the ARM3 is currently unique among Linux
- machines in that it absolutely _cannot_ do an unaligned access. The Intel
- will do the access happily; the Alpha and the SPARC (and the ARM6+ with
- MMU on, I think) will fault and you can emulate it in software, but the
- ARM3 will silently discard the low address lines. Other than that,
- someone will need to write an installation system and the rest is just a
- question, as you say, of compiling things up.

- Indeed. With this (and X as well) we should liase with the NetBSD people.

- It could do. Things like BBC BASIC and Norcroft C might be beneficial to
- be able to run under Linux, and I don't think it even ought to be too
- tricky.

- That certainly does seem to be the state of play at the moment.
