Well... I'm not sure about the 16 channel mods... namely because IO will still run at standard SAM speeds (well, IO to any ASIC driven port will... below 248, I think it'll run at full speed). The cost? Well, we're still working on that. Let us build up a prototype first. I'd say that under fifty pounds is overly optimistic... and under 80 may be possible, but probably unlikely. >Next question, how's the >hard-drive (or dos) coming along?

Well the hard-drive is currently undergoing timing testings to try and work out why I'm getting spurious data reads back if I don't read the DRQ bit between each data read. Time to build up a new prototype I think. Nev's hard drive isn't much further along either - I've heard that this is because he's relying on being able to write the DOS in SAM C (he doesn't like machine code). Also, he's recently hit problems with his interface seemingly being only compatible with the first drive he tested... probably the same probs that we've been having.... As for the DOS, I'm designing new instructions, and trying as hard as possible to work out how to make the DOS sectional so that you can use BOOT 1 for a mini-just-get-it-going DOS, BOOT 2 if you want all of the extras (BOOT 2 will be a 32k dos, boot 1 a 16k one). If anyone has any ideas for new DOS commands, and/or hook codes I'd be more than happy to hear them. I'm also going to try to put in support for Steve Taylor's LOAD * command too, if I ever get around to hacking his code. Time is short, alas.
