At UCLA Western Data Processing Center (709 - 1090 - 1094) we processed 
remote jobs, but card images were transmitted in to a high speed (500 
CPS?) paper tape punch, converted to mag tape using an off-line 1401, 
and fed to a batch processing OS on the mainframe.

The 7090/94 and a 1410 were connected to a shared 1301 disk drive.  I 
worked on a 1410 system that replaced the off-line 1401s by putting jobs 
on the 1301 and spooling printouts from the 1301 -- no tape mounting and 
the 1410 could have multiple card readers and printers.  (The 1410, 
unlike the 1401, could handle I/O interrupts and it had indirect 
addressing).  We had lots of hardware hassle -- the 1410 was built by a 
different division within IBM than the 1301 and 7000 machines.

Memory lane ...
