I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Additional notes, comments on style, and whatnot are welcome.
(It may be sensible to send anything in the last two categories
directly to me, rather than to the whole list.)
Does anyone know (remember) which Unices had .../bin/[ be a link
to .../bin/test. I remember this being the case, but it is not so on
any recent Solaris. It is the case on my Mac, so in at least one BSD
derivative. I looked through a 7th edition tarball from the archive
and it's not the case there. So my guess is that it is a BSDism, and
it probably was the case in SunOS 4 and before, and I guess on at
least 4.2BSD & later.

Sorry! I think I was actually talking about a different Bell title. I
checked my past orders and found the following:
Author: Bell, C. Gordon; Newell, Allen
Title: Computer Structures: Readings and Examples
Author: Siewiorek, Daniel; Bell, C. Gordon; Newell, Allen,
Title: Computer Structures: Principles and Examples
Both of these contain many architectural case studies (each book
covers a different set). And both should be findable in this list:
I also have Computer Engineering but it's a different book! Sorry
again about the confusion.

I just bought a copy on eBay a couple of weeks ago, and have just read it
cover to cover. A bit dry at the start, but fascinating...I starting using
PDP11s back in 1972. (an 11/20)
And used what I think was the first v6 UNIX system in England...
Having long ago got rid of my collection of ageing British (super)
minis, I realise I'm missing them, though I'm not sure why. I can't
pretend any more that something running 4.2BSD is really practical,
so I'd like to get something really impractical, like a pdp11.
What I'd like to be able to do is run 7th edition or thereabouts and/
or 2.11BSD on something which is not too large (so full-height 19"
racks are out). I'm not interested in emulators. It looks to me
like there are such systems - for instance the recently-discussed
11/23 (or 11/73) looks practical, other than being in Utah.
So I guess I have two questions:
Firstly is this a practical thing to do in terms of reliability of HW
etc? I finally gave up on the previous lot of machines at least
partly because disks &c were just so flaky that it was too painful to
keep things working (also we're talking full-height 19" racks in some
cases so they were a bit, well, big). I don't want to spend my life
trying to source ancient disks etc (though I'm clearly not expecting
things to be as reliable as good, new modern kit).
Secondly, does anyone in the UK (may be there is no one but me, of
course...) have any hints where I might look and what I might expect
to pay. I've looked on ebay but I'm a little nervous of what I might
get that way.
