Talk:IBM 7-track

Table alignment
Hi RTC, thanks for the great data on the old tape units. I see you changed the formatting a bit. Does the table on the right and text on the left not work on your screen? -- Austin Murphy 13:12, 25 July 2006 (UTC)


 * All I added to the format was a because the section on the 726 was flowing one word on a line down the left edge of the table, making it unreadable. I didn't touch the table formatting itself. -- RTC 16:25, 26 July 2006 (UTC)


 * The effect is that, on my screen now, instead of text on the left and table on the right, there is blank space on the left and table on the right. What you are saying makes sense.  I need to come up with a better layout that doesn't have one word to a line on smaller screens and large blanks spaces on larger screens.  -- Austin Murphy 17:41, 26 July 2006 (UTC)

Old tape drives
Another article on IBM 9 Track should probably be started for the drives that they introduced starting on the System/360. But I don't have much info on them yet... -- RTC 16:34, 26 July 2006 (UTC)

Other manufacturers and computers
I know DEC sold IBM compatible 7-track tape drives for their 36-bit PDP-10 computers, the KA10 and KL10 processors for sure. A bit of research just now indicates GE and then bought by Honeywell's 36-bit computers also used 7 as well as 9 track tapes as a vaguely remember WRT to the Multics version. No way these companies bought drives from IBM, although the difference between a 7 and 9 track drives once the latter came out would be as little as different heads and related electronics.
