Interesting. I never used much IBM hardware, and always assumed that their terminals used EBCDIC and not ASCII.
The HP 2648A terminal also had a "block mode", and the RTE screen editor used it. It was one of the first screen editors I ever used (in 1984). (I had used WordStar on CP/M as early as 1979.)

- monocasa 2y agoTheir mainframe terminals do, and that's one of the conversions their script has to make. The 3151 was designed to integrate with other systems where ASCII was already prevalent.
- unoti 2y ago> I never used much IBM hardware, and always assumed that their terminals used EBCDIC and not ASCII. Generally this is true. But around this era I used a ton of 3151 terminals on AIX, IBM's version of Unix. They were connected to the RS/6000 line of AIX machines. Good times! These machines, as Unix machines, talked in ASCII to their terminals. There was a whole line of port concentrators which would like you connect something like 32 ASCII terminals to a little block about the size of a modern ethernet router, and you could connect 4 of so of these blocks to a device in the main machine.
- anonymousiam 2y agoGood info. I've also used AIX, but more recently (after 1995). By then, I think EBCDIC had lost the standards battle.
