Ditto for the 386BSD BSD/386 line of  code. I think they were added in the patch-kit phase, not the original Jolitz code phase. FreeBSD 1.0 Beta had them in 1993 for sure, as did NetBSD of the time.

I have a memory of them on 0.98pl13 on Linux as well, but that version sticks in my head as a proxy for anything between 0.96 (the first one I tried) and 0.99 (the last before 1.x Linux). This would be approximately 1992 or 1993.

I've not done the deep-dive into the ancient code bases to see if I can suss out when they arrived.
 

Virtual consoles were added to Linux in Version 0.12.  They may have been available in 386BSD and FreeBSD 1.0 but it looks like they were not configured by default until FreeBSD 1.1.
