Both the speaquilizer and braillex had that great advantage to them. The real problem is the pci and before that, the vesa local bus and all that. Sure, I guess the ultimate solution is to somehow add code onto a video card or something... or in this day , perhaps an externa computer which takes care of video work for the main system... I've seen some sgis that do that. Unfortunately, this doesn't seem like it would work out of the box with modern systems. although there could be a convention with some systems out there to tell it to display to something via bios or some kind of hardware arrangement. This really is the problem with virtually all the hardware out there... whether it be a tivo, some computer you walk up to or any other kind of highly computerized device. Life would be much easier if you could just somehow tell it to display somewhere else ... alternative input seems to be much easier. I did see a mac once, which was custom built for high end graphics work of a particular kind. it could have different plotters and displays connected to it over it's ethernet connection, which it was aware of as it was brought up. I'm not sure what had to be done to make that happen, but it was pretty cool. I saw some potential then. Anyone notice you can't even buy isa video cards now? and some computers don't have the slots? I guess it doesn't pay to make cards like that now when we dont settle on an archetecture for more then a few years. I've heard some rumblings of embedded rt linux doing the graphics work for some systems. that would be as close to hardware as I think you'll see. You could just add some code into the rom of the rt linux system to redirect the video read information to another port and the main processor would never know. then your bluetooth aware speech synth would tell you when things started happening? oh wait, sorry that was a dream I had last night.

Admittedly my understanding of how this works, and indeed of the hardware side of things in general means that I can't actually hazard much of a suggestion as to the way forward on this. My prompt for thinking about this was that by pure chance, I still happened to have a hardware driven Braillex display connected to a machine I was trying to install Linux on, that I hadn't realised would work with Linux. After several posts to this list earlier in the year, I was very grateful to receive helpful suggestions on how to get this working, and it is really so much easier to use, and gives acess so much earlier in the boot/install process that it seems a shame to abandon it without some sort of discussion about revisiting this solution. The hardware solution became more or less obsolete for Windows access, when screens could no longer be relied on to be a fixed size, (although thinking about it, I'm not sure why this should have been such a problem). For 25-line X 80-column screens, its very hard to beat. When I switch on my machine, I see the memory check, and BIOS password prompt, and then all the information even before the kernel is booted. Even though I've tried brltty, and found it to be an excellent piece of software, it still doesn't provide the snappy response to braille navigation functions as the hardware solution. Obviously the disadvantages are pretty numerous as well, though I'm not sure how many of these are features of the age of the technology. You have to install a video card which is compatible with the Brailex interface card. The display is then driven vai a cable which connects to the braillex card rather than to one of the standard ports. The keyboard connects to the machine via the Braillex, so that cursor routing can be carried out via the keyboard cable. All of which means that its certainly not as easy to walk up to a machine and set up access to it, as it would be using brltty or speakup etc. Anyway, this seems to have turned into vague meanderings rather than any specific suggestions, but I'm interested to know if anyone else thinks the hardware solution still has some miles left in it.
