Umm, yes it did. V7 and pre2.6 BSD both could be booted and run from paper tape as well as RP02s. Required all 4 core plane mobys installed on the PDP chassis and the SAIL modified address multiplexor hardware, but it would work. 2.6BSD and higher required at least one RP03. I think what Rich is referring to is the common practice of Lesser Mortals (ie ordinary users) were often forced to store their programs on paper tape because most sites couldn't afford enough disk to do permanent online storage. You did a lot of 'cat < /dev/ptr > /tmp/foo.f' in those days. Paper tape was widely used for program storage and data storage, especially if you were privileged to have a HSPTP/R unit (the 300 ips one). /dev/ptr and /dev/ptp were your Very Good Friends. Otherwise you were stuck with 110 cps /dev/tty. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
