マイコン独立大作戦
ＣＲＴ/VGAIF+KEYIF+SDCARDIFボードの製作
～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
ＷｉｎｄｏｗｓパソコンにＵＳＢ接続して使う現行方式はそれなりに便利ではありますが、ときとしてＷｉｎｄｏｗｓ
のしがらみから開放されて、小さいながらも独立した一個のパソコンとして機能したいと思うこともあります。
昔はそれが普通のことだったのですが、安価なＣＲＴディスプレイが生産中止となって久しい今日ではそれ
は叶わぬことと諦めていたのですが…。

●ＬＯＧディレクトリの修復（３）
前回の続きです。
前回はＳＣＴＲＤ．ＢＩＮを実行することでユーザーズエリアの先頭クラスタ（＃２）はセクタ№２８３になることを確認しました。
前回も書きましたように、これはこのＳＤカード固有の数値で、同じ２ＧＢのＳＤカードでも個別に少しずつ№が変わります（たまたま同じ№になることもあります）。
ユーザーズエリアの先頭クラスタ＃２はＺディレクトリに割り当てています。
前回はそこまで説明しました。
クラスタ＃２のＺディレクトリはＷｉｎｄｏｗｓからアクセスするためのＦＡＴ１６フォーマットです。
その次のクラスタ＃３にはＣＰ／ＭフォーマットのＺディレクトリを置いています。
クラスタのサイズは６４セクタ（４０Ｈ）ですから、クラスタ＃３の先頭セクタ№は２８３＋４０＝２Ｃ３です。
セクタ№２Ｃ３を読んでみました。

という調子で順番にセクタを読んでいきましたが、その過程を全部ここにＵＰするのはあまりに冗長ですから途中は省略することにします。
ずっと順番に１セクタずつ読んでいきましたら、ついにセクタ№３０Ｆでゴミが現れました。

途中におかしなファイル名があります。
ここが目的のセクタのようです。
［総合第１５６回］の画像では０２２４１９０１．ＬＯＧを表示したあとゴミが表示されて、そこでハングアップしてしまいました。
このセクタのゴミを取り除けば多分正常にＤＩＲＬコマンドが実行できるようになると思います。
念のため次のセクタ№３１０も読んでみました。
