But in between those [Batch vs. Terminal], there was an era of 'interactivity, but not as we know it', when computers supported interactive work by teletype. Not really. To start with, these were complete different usage scenarios. Batch didn't turn into terminal use - or got replaced by it. Batch is like mass production on industrial scale. It still ...

I believe the only way we can answer this question is by members finding 'the earliest' such description. DEC's first CRT terminal device, the DEC VT05 terminal (1970), had tab stops fixed at 8-character intervals. The DEC VT50/VT52 terminals (1974) had tab stops fixed at 8-character intervals. The DEC VT100 terminal, (1978) which replaced the VT52, had tab ...

A few pieces: Why does one so often hear of payroll, specifically, being an early application of such systems? It seems to me this is partly because the payroll of a big company involved a lot of repetitive calculation, but also because it's particularly amenable to that sort of processing: multiply hours worked by hourly wage, output pay due that worker ...

For a relatively late example which you could run today under an emulator, I would suggest dBase II, a database program for 8-bit microcomputers. As the Wikipedia article goes into, it was based on an earlier program for mainframe computers. The CP/M version worked with dumb terminals, and I bet at least some early users had printing terminals. This ...

First, Payroll is really apt for batch processing. It runs once a week or twice a month in general, and it tends to be all done at once on "payday". So each week the operators key in the time cards, then they process them, they run and audit the reports, then they cut the checks. Big, meaty processing tasks done in bulk, vs high density transaction ...

I was a student pilot in the late 60's and teletypes were used as terminals to the weather services. I would consider that an end user interactive system. As I remember, it was line command driven and the speeds were slow enough that there were lots of abbreviations used to cut down on the characters transmitted. This was confusing and could easily lead to ...

[No time for a real answer (got to push my narrowboat from Wolverhampton to B'ham), but ...] This page (which is a marvellous collection of TTY manuals) does have at least two charts (7171WD, 7172WD) showing their encoding/population side by side (caution, strange PDF settings).
