Re: [TUHS] Unix quix

[Heinz Lycklama <heinz@osta.com>]

Jon, your dates are correct on MERT. I think UNIX v6 was introduced
in 1975. So we may have used v4 in 1973 and then upgraded to V6
later on in preparation to the general release of MERT 0. Clem, you may
be able to confirm this from the MERT 0 manual you borrowed from me.

Thanks.

Heinz
