[TUHS] NFS at 40

[Charles H. Sauer via TUHS]

Yes. Dell SVR4 definitely included Lachman NFS. I booted Dell SVR4 earlier this evening and saw 1987/8/9 Lachman copyright notices. Lachman NFS might have been bundled in SVR4 by USL.

For (Dell) SVR3, I’m pretty sure Lachman NFS was separately licensed. Dell SVR3 development was before my time there, so I don’t know for sure.

As I think has been previously discussed on TUHS, I was part of IBM licensing NFS directly from Sun to be included on all IBM platforms, not just AIX. For AIX for RS/6000, there would have been no Lachman involvement. I assume that was also the case for AIX/370 & AIX PS/2.

I also assume that other large companies, HP, Digital, … would not have used Lachman, but worked directly with the Sun code.
