[TUHS] UNIX V 6.9999999 ?

[Jason Stevens]

While cruising olduse.net I came across this puzzling entry in net.general


            Department of Computer Engineering and Science

                    Case Western Reserve University

                            Cleveland, Ohio



        We would like to announce our connection to Usenet. We are a

private university located in Cleveland, vacation spot of the midwest.



        The department's primary facilities consist of:



        VAX 11/780: hardware: RM05's, TU77, DZ-11, DH-11 (able), 2.5 Mbytes.

                    software: 4.1 BSD



        PDP 11/45:  hardware: RM02, DS330 (RP04), RK05, RX02, RS04(solid
state)
                              cache45 (able), DH-11

                    software: UNIX V 6.9999999



What is UNIX V 6.9999999?? I suspect it's v6 with a bunch of patches, but
not quite v7?  I've seen from some Russian stuff that they prefered v6 on
pdp-11's as it "ran faster" than v7 and needed far less ram/disk space... I
know it's 30 years too late to ask them what it is but I figure someone may
have actually ran/used 6.9999999...


Thanks

That is kind of what I'd imagine... In 1983 I thought 160kb was infinate
storage.. lol

You mean both of them?

[TUHS] UNIX V 6.9999999 ?

Ah that makes sense, I could totally see that happening.. Esp with the cost
of hardware back then!  It is insteresting reading about people haveing
600MB of storage back in 1981.. I can only imagine how much it'd have cost!

Thanks again!

Back in the V6 days, I was known as Mr Unix 6-and-a-half, because I'd 
spliced all sorts of V7 features into V6 - notably XON/XOFF, and there was 
no way that V7 would run on the 11/40,

I rewrote the Calcommp and Versatec plotter drivers to use the block 
interface, and they went like a bat out of hell.

Sigh...  We had fun in those days.
