Talk:IBM 726

I commented out the following text:


 * Aluminum strips were glued several feet from the ends of the tape to serve as logical beginning and end of tape markers. Write protection was provided by a removable plastic ring in the back of the tape reel.

This was true on the IBM 727 and later drives, but may not have been true on the 726. I saw in one document a mention that the 726 used steel tape leaders. -- RTC 05:34, 12 July 2007 (UTC)

parity
As well as I know, 7 track tapes were used as either even or odd parity. Even parity meant that the character with all zero bits couldn't be written. S/360 drives can read/write either way. Gah4 (talk) 00:32, 7 January 2019 (UTC)
