[HECnet] Questions about the E11 version 0.9 release

[Gregg Levine]

Hello!
In going over my collection of things PDP-11 I came across a some what
startling discovery. That of this one, I have nearly all the releases
of E11 from the 0.8 one all the way to the recent one.

The 0.9 release was retrieved from GENIE back when it was trying to be
the same as Compuserve, and that was around 1994. (Both have since
folded it seems.) At the time I was just beginning to understand
exactly what I had obtained from that site. I didn't. I do now.

Now I've gone and read all or nearly all of the documentation file
that it came with. There are two instructions there, one of is the
SWITCH one, and I quote here:
"SET SWITCH n
SET SWITCH PORT n

              If PORT is specified, specifies the octal 80x86 I/O address of a
              word port which when read as a word, gives the current 16-bit
              switch register value.   Otherwise (PORT not specified), sets the
              value of the emulated SR to the octal number n. "

And the other one is named this DISPLAY one, and I quote here:
"SET DISPLAY NONE
  SET DISPLAY PORT n

          If PORT is specified, specifies the octal 80x86 I/O address of a
          word port which when written as a word, sets the 16-bit display
          register.   If NONE is specified, then anything written to the DR
          by the PDP-11 is ignored (the default condition).   So if you
          want to see pretty blinky lights, get out your wire wrap tool
          and a couple of 74LS273s and whatever else."

And of course my question is one of, were those actually tested with
real hardware attached?

John I imagine you are aware that these early releases are floating
all over the Internet?
