Thou shalt have no other gods before the ANSI C standard 1362

2741 was beefed up selectronic typewriter (golf-ball) ... it was in self-contained desk high package .... basically something like a computer table ... with the typewriter embedded in the table. it was 134.5 ... slightly faster than 110 to be incompatable line-speed.

here is picutre of 2741 looking somewhat down from the top.

(with respect to the above ... i have a 2741 apl golfball sitting on top my display). i started long history of pretty continuous home online access with a 3rd party "portable" 2741 (two 40lb suitcases) in mar. 1970 ... but soon got a "real" 2741 at home which i had into the late '70s.

when i was undergraduate ... i came up with this neat terminal identification sequence that could handle tty, 2741, and 1052s ... the mainframe terminal controller actually had a command that you could dynamically buttign the terminal-type specific line-scanner to any port. so i had this magic code that ran thru a bunch of sequences to figure out the terminal type w-o having to pre-specify it. it worked when the terminals were hard-wired connected to specific ports ... but i also wanted to have a single phone pool with single dial-in number for all terminals. that was when the local hardware people pointed out that they had taken a short-cut with the terminal controller ... and while you could buttign an arbitrary line-scanner to any port ... specific speed oscillators were hardwired to ports ... aka a specific port was hardwired for either 110 or 134.5 ... even tho on could use tty, 2741, and-or 1052 linescanner on every port.

so that somewhat kicked off a project to reverse engineer the ibm channel interface and build own channel interface card to put in interdata-3 and program the interdata-3 to emulate an ibm terminal controller (the interdata-3 had software linescanner and was programmed to do automatic line speed detect).

somebody wrote this up as helping spawn the plugged compatable controller bussines ... and i'm getting blaimed instigating it.

later ... when the future system effort was started ... some amount of the documentation says that it was targeted as having a much higher degree of box integration as a countermeasure to the plug compatible controller business

while FS was eventually cancelled ... there is some stories that at least some motivation for cloan mainframe processors were engineers that wanted to keep on producting 360-370 machines ... while the corporation was saying that they were going to have as bigger transition from 360 to FS architecture than there had been from pre-360s to 360 architecture.
