Remember, it is called the 1403 because it was originally built for the 1401 computer.
IIRC there were several iterations of speed before the 360 came out, and the N1 with the power lid and sound baffling. from AI: No, not all IBM 1403 printers had interchangeable type chains: Note that while the IBM 1403 Models 2 and 7 do offer a feature known as the Interchangeable Train Cartridge Adapter, which allows the operator to easily remove and insert a chain cartridge with a different font or character set arrangement, this feature does not have a separate machine type. Yes, I had forgotten the name, we had a TN chain we used for one or two jobs. The IBM 1443 printer could also do 144 columns. With the 1404 printer, one could install blocks to print on the shortie 51 column cards. We hated doing that, it did not fit well. <pre>--Carey</pre> > On 12/21/2024 2:30 PM CST Paul Koning <paulkon...@comcast.net> wrote: > > > > On Dec 21, 2024, at 12:41 PM, CAREY SCHUG via cctalk > > <cctalk@classiccmp.org> wrote: > > > > my recollection from being a computer operator at the time was the the > > earlier 1403s did NOT have an interchangeable chain. > > Interesting.
