Nexterm SV-II [Computer and Networking , Junk ]

某所よりシンクライアント端末 Nexterm SV-II [TUL TC3500]をゲット。CPU は VIA Eden 533M、メモリ 128M SO-DIMM それに 32M CF。スペック的にはしょぼしょぼ。そこはそれ、千円札１枚であそべるおもちゃということでひとつ。中をみるとセカンダリの IDE らしきコネクタがでている。2.5inch IDE-HDD のものとそっくり。試しに HP t5730 から取り外した 1G のフラッシュメモリを挿してみるとぴったり収まり認識された。右の写真で手前側の緑の基板がそれ。CF は抜いている。外装からすると色々カードの類が装着できそうだが、それらはオプションなのか付属していない。

試しに OpenBSD-4.6/i386 をインストールしてみた。

dmesg はこんな感じ。

128M メモリはやはり結構厳しくて素の puppy linux だとやっと、FreeNAS は現行版だと起動に失敗した。今どき SO-DIMM は却って高くついてしまうから増設は微妙なところだ。
