I can remember as a consode operator running a 360/30 in 1401 compatibility mode (dialing in the card reader address and loading in the 'CID' deck). I can also remember settubg the 'F' switch to signal the last reel of tape being read in on a 2401 tape drive.
We also ran that machine in normal '360' mode, IPLing DOS off the 190 disk. --- On Fri, 5/29/09, Jim Bohnsack <jab...@cornell.edu> wrote: > From: Jim Bohnsack <jab...@cornell.edu> > Subject: Re: IBM 1401 > To: IBMVM@LISTSERV.UARK.EDU > Date: Friday, May 29, 2009, 11:39 AM > No, the IBM 2671 paper tape device > was a reader only.
