土砲一般都是用好幾片小電路板拼湊而成.</span><br /> <span style="font-size: large;">4. 廠機內部都很緊湊; 土砲機內部常常空蕩蕩.</span><br /> <span style="font-size: large;">5. 廠機一般都是獨創線路</span><span style="font-size: large;">/外觀</span><span style="font-size: large;">; 土砲則常常仿造廠機.</span><br /> <span style="font-size: large;">6. 廠機的外觀是協調美麗的; 土砲則是土味很重.</span><br /> <span style="font-size: large;">7. 廠機外殼是專用的, 若是類似外型則會有型號/名字作區分; 土砲則是一種外殼裝好幾種線路, 除了拆開來看內部外誰都不知道裝啥線路.<br /> </span>oldhanhttp://www.blogger.com/profile/02219751893905430147noreply@blogger.com0tag:blogger.com,1999:blog-7891831236409681525.post-60785261644695718672008-02-22T14:58:00.002+08:002010-10-08T08:49:50.244+08:006AK5 轉 12AT7 轉接板, 可以快速聽一些冷門管子的聲音.<br /> 自己洗的板子完成圖. <br /> <img src="http://lh5.google.com.tw/alphatec002/R75fiy9vcLI/AAAAAAAABDg/e_5PLenFZvg/s400/PICT1124s.jpg" /><br /> <br /> 拔掉真空管的轉接板<br /> <img src="http://lh4.google.com.tw/alphatec002/R75fii9vcKI/AAAAAAAABDY/WVF8cXUOEM0/s400/PICT1123s.jpg" /><br /> <br /> 反面接腳<br /> <img src="http://lh4.google.com.tw/alphatec002/R75fii9vcJI/AAAAAAAABDQ/RhZq-t8H9FM/s400/PICT1122s.jpg" /><br /> <br /> 真空管座的 pin 腳由此 D type 電腦插座拆下<br /> <img src="http://lh5.google.com.tw/alphatec002/R75fiy9vcMI/AAAAAAAABDo/NQdOlAKZ968/s400/PICT1125s.jpg" />oldhanhttp://www.blogger.com/profile/02219751893905430147noreply@blogger.com0tag:blogger.com,1999:blog-7891831236409681525.post-84494019479341865992008-02-20T14:36:00.001+08:002008-02-20T14:39:33.879+08:00五六年級同學有玩過電腦的應該記得這部世界第一台成功的個人電腦: Apple II, 看著她多少回憶湧上心頭, 就像初戀的感覺. 許多人因為這台電腦而致富, 如今記得的人聊聊可數..<br /><br /><object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/YcjlhFVTY50&amp;rel=1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/YcjlhFVTY50&amp;rel=1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object><br /><br />看完後有點感動, Jobs 與 Woz 兩人應該熱情擁抱而不是虛委的握手而已..oldhanhttp://www.blogger.com/profile/02219751893905430147noreply@blogger.com0tag:blogger.com,1999:blog-7891831236409681525.post-75276752261219492952007-05-15T13:55:00.000+08:002023-05-03T10:59:28.349+08:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJQYGUX8a6HSGf8nUw5h6RSnES6ZUNnkGHjfs9zBAi__TDi4-qFXE9ap_skdofMEdhf_SYG2IMHUEQE2vxJZepoZvJ5GcTY2j6d6u-nax-5TtPEFx2Il16uBWKRQ5LSMu_4GwOUtNGY_8/s320/Resistor+box-1.jpg" ><img style="margin: 0pt 10px 10px 0pt;
