IBM, in contrast, tried to coerce perforated tape into the unit record mold. I recall that there were legendary difficulties reading on a 1620 tapes that lacked the necessary record separator codes. I think the symptom was overflowing buffer and wrapping memory. I don't know if it stopped when the READ instruction was finally overlaid. I don't recall whether the deficiency was in the control unit or the FORTRAN runtime system. >> One of my first real jobs was hooking a 33ASR to an 029. So the AT&T toll information could be 'punched' for the billing system. The AT&T tech couldn't view the IBM manual and the IBM CE couldn't view the AT&T by copyright/legal working agreement. We put an eight pin terminator strip on the wall between the two machines. Didn't work. Well, what's you DTR---finally the IBM guy needed a break and laid his manual to the page on the 029. We decided we need a break too and laid our manual on the chair to the page-funny thing after the break was over. The thing started to work! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
