Intel intellec MDS-800 是大三大四時實驗室的微電腦.

是8080 CPU, 8吋 Floppy Disk-應該很少人看過這麼大的磁片吧!

有終端機 ICE (In-Circuit Emulator) 與EPROM 燒錄機.

最重要的是他有 PL/M-80 等高階結構式語言.

我還用PL/M, 來開發邏輯電路模擬程式, 把Counter 輸出的波形 從Line Printer上列印出.

那時也和其他同學,參加老師的工研院作業系統研究計畫, 把這機器的作業系統Trace出來.

也就是從這裡開始,了解了磁碟檔案的結構及Open, Read, Write, Close 及 Delete 等功能的.

他的BUS 叫MultiBus. 可接多塊SBC單板電腦 及Common Memory Board.

我也曾用它寫個波形信號產生器來作硬體電路測試用,相當好用.
