[HECnet] NOTES system?

[Clem Cole]

the ANSI spec was started before the vt100 project.   I once had an mid ??1970's??? draft.   but iirc it took a couple of years to go from draft to final spec.   

decent started the vt100 using the vt52 sequences but because it was based on a micro (8080 iirc) there was a push to write ANSI compliant firmware.   when ANSI was not finalized dec decided to put both modes in and ship. 

again I've forgotten the details.   as I recall the vt100 does not do insert and delete properly.   again my memory is the first fully ANSI   conforming product was the Ann Arbor Terminals Ambassador   which was About 3 or 4 years post vt100 release.     Clem

we had a bunch to test with which is why I remember that detail.

And yes, the VT100 predates ANSI, but it's not really incompatible, but there are a bunch of DEC private sequences, that are not in the ANSI spec.
I'm not aware of any incompatibilities with the ANSI spec, but feel free to point them out to me.

What's the history of the ANSI spec?   I've always   just assumed that it codified what was being used in the industry already.
