LINCtape

LINCtape

(storage)A formatted, block-oriented, high-reliability,random access tape system used on the Laboratory Instrument Computer. The tape was 3/4" wide.

The funny DECtape is actually a variant of the originalLINCtape. According to Wesley Clark, DEC tried to "improve"the LINCtape system, which mechanically, was wonderfullysimple and elegant. The DEC version had pressure fingers andtape guides to force alignment as well as huge DC servomotors and complex control circuitry. These literallyshredded the tape to bits if not carefully adjusted, andrequired frequent cleaning to remove all the shedded tapeoxide. That was amazing, because the tape had a micro-thinplastic layer OVER the oxide to protect it. What happened wasthat all the forced alignment stuff caused shredding at theedge.

An independent company, Computer Operationsbuilt LINCtapedrives for use in nuclear submarines. This was based on thetape system's high reliability. Correspondent Brian Conversehas a picture of himself holding a LINCtape punched full of1/4" holes. It still worked!
