I think the L100 HAS the mouse/PS2 on its mini-dock It does but there's 2 problems. Firstly, mine didn't come with a mini-dock, only the EPR. Secondly, even if it did, thats a pretty bulky thing to have to carry around. I'd rather cut the connector off a small mouse, replace it with a flat connector and be able to plug it into the libby like what Xin has done. Ditto with a little keyboard adapter (so I can commandeer a keyboard when I need one). > if > that works I'll also make an attempt at bringing out the USB lines (I'll > have to find somewhere to take a few volts from to supply the USB power > lines though).

But I hope for your sake I am wrong The EPR has the USB port and probably the USB power circuitry but I noticed that the docking connector has USB out lines which sorta implies that the USB smarts are actually on the libby side of the docking connector. Of course, I don't know if there's any buffering circuitry or whatnot in the EPR ... I also found the serial lines on the docking connector so I might also try bringing the serial lines out to a flat connector as well and see if I can't get it to work with my Palm folding keyboard or a chording keyboard (imagine strapping the libby to your belt or non-dominant forearm and typing with the same hand using a chording keyboard ... all you'll need is a spectacle- projection system and a couple of extra LiIon battery packs and you've got a wearable computer!). IIRC Windows's accessibility options does allow for a serial port keyboard replacement which I might be able to convince to work ... I don't think I'll need an RS-232 line driver given the palm folding keyboard is port-powered anyway. Failing that there's always the option of doing a serial ASCII to PS/2 keyboard converter in a PIC16F84 ... hehe - Raymond ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives -------TO UNSUBSCRIBE------- Reply to any of the list messages.
