x2yz would be a terminal type device (e.g. 2260, 3270) x3yz would be a disk type device (e.g. 2301, 2311, 2314, 3330, 3390) x4yz would be a tape type device (e.g. 2400) x5yz would be a card type device (e.g. 2540) x7yz would be telecommunications type device (e.g. 2701, 2780, 3780)
In all cases x=2 would be "second generation," i.e. System 360; x=3 would the "third generation," i.e. System 370. x=1 would be first generation and is a different numbering scheme -- e.g. 1052 is a console, 1403 is a printer. IIRC the S/360 CPUs were, e.g., 2040 for the 360/40 and the S/370 CPUs were, e.g., 3155 for the 370/155 Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Seymour J Metz Sent: Sunday, March 21, 2021 12:49 PM To: [email protected] Subject: Re: z/TPF questions > The 3215 was the s/360 console printer keyboard No; the 1052-7 was the console typewriter for various S/360 models. The 3210 and 3215 were console typewriters for low end S/370 models, eventually replaced by special models of the 3270, e.g., 3278-2A, 3279-2C. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
