From: balrog Date: Mon, 2 Jun 2008 01:33:11 +0000 (+0000) Subject: Provide basic emulation for Sharp SL-6000 PDA (Tosa), Dmitry Baryshkov. X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=89cdb6af04c16c5476221b1f2d25d8337ebbb391;p=qmiga%2Fqemu.git Provide basic emulation for Sharp SL-6000 PDA (Tosa), Dmitry Baryshkov. This adds basic support for emulating Sharp Zaurus SL-6000 PDA (tosa). Currently it provides only basic support: no kbd/lcd, sound, ts, etc. But it's able at least to boot Linux from CF.
