• ISLEから借りていたメモリの代わりに予備品の256MBメモリ(Buffalo, メモリチップはELPIDA製)を取り付けてテストしてみた。 vcheckは正常にできるが、DSPボードテストでメモリにエラーが出る。

• メモリ予備品の初期不良かもしれないので、もう一枚購入してみる。

[20081017]

• 新たに購入した256MBメモリをとりつけてテスト。全く状況に変化なし。vcheckはエラーなし。
• ISLEで使用しているメモリをつけてみる。結果、エラーなし。

• 原因が分からないが、相性の問題かもしれないので、 ISLEのと同じTranscendのSO-DIMMを購入してみる。 スペックシート

[20081024]

• TranscendのSO-DIMM TS32MSS64V6F (32MBx8=256MB)を装着

• cd /usr/local/dsp21ksf/bin
  export DSP21KSF=/usr/local/dsp21ksf
  ./dspbad -d0 -i1 -tn
  ./dspbad -d0 -i1 -td
  ./dspbad -d0 -i1 -tp
  

  いずれもエラーなし。 vcheckも問題ない。

[20081027]

• デュワーについている真空計の内部を清掃した。

[20081028]

• モレキュラーシーブのベーキング(使用済みのものの再生). 2時間
• モレキュラーシーブと真空計をインストールして真空引きを行おうとしたが、 真空計が"Error Hi"の表示.

[20081029]

• 真空計を再度分解して組み立て. エラーは出なかった. 9:00真空引き開始

• 10/29 09:00 5.0e-3 torr

• 途中から真空ポンプDCUにE698というエラー表示。マニュアルによると、"TC does not respond"
• 停止させようとしたところ電源OFFボタンが効かなかった。カバーを外し、内部のコントローラ電源を落としたらターボ分子ポンプが停止した。
