[cctalk] Re: Print chain for 1403

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 whil

[cctalk] FTGH IBM 4245 Printer Bands

Anyone have an IBM 4245 printer? I came into a box of NOS print bands and have zero use for them. Don't want to hard them, don't want to throw them out. FTGH, pitch in a couple of bucks for shipping and they're yours. I can get part numbers and quantities if there's interest. There's about a doz

[cctalk] Re: Print chain for 1403

my recollection from being a computer operator at the time was the the earlier 1403s did NOT have an interchangeable chain. Also curious if any 1404 printers still exist. They were wider and you could shift the print mechanism to the side where there was a mechanisms to print on tabulating card
