Installing ICL George 3 on Linux

Wanting to recapture my misspent youth with George 3 (undergraduate at UEA 1977-1980 on an ICL 1903T, working for University of Hull computer centre in 1982-83 on a 1904S and 2966 DME) I installed it on my Debian laptop.

Since the only publicly available version of g3ee is for Windows I run it under Wine. (I would like to run it on my home server, but that is an ARM machine, so I'd have to run Wine under QEMU, which would maybe be an emulation too far...)

Here's the recipe:

Download g3ee.zip from http://www.icl1900.co.uk/

Unzip the g3ee.zip file:

$ pkunzip ../George3/g3ee.zip

move to the "bin" directory:
```
$ cd bin
```

Launch g3ee using wine to boot from tape:

$ wine g3exec.exe -d ../data -c1900 -m256 FI G3MK8D ../tapes/4670000


George 3 Executive Emulator

Waiting for a console telnet connection on port 1900

On another terminal use telnet to connect to the operator console

telnet localhost 1900

Now give the "CR 04" command on the operator console to load the instructions from the card reader (file data/CR04)

Tell the system which tape we want to load - 1, 2 or 3. See here for details of what's on each tape. You are stronly advised to start with tape 3, unless you realy want to get a close to a bare install as currently possible.
```

MT 4670000 NOT INCREMENT DUMP TAPE
PLEASE ENGAGE INCREMENT 3
    
```

It's not happy with the tape that's online so we ask the operator to change the tape for us by typing control-B followed by the command "M31,serial" where serial is 15155 for increment 1 (a naked system), 15156 for increment 2 (a configured system) and 15157 for increment 3 (a "complete" system).

When it goes quiet (it's very quick) tell George to shut down by pressing TAB and entering the "FINISH NOW" (or "FN NOW") command:

   FN NOW
20.09.44 SYSTEM CLOSING DOWN NOW
ALL USER JOBS NOW FINISHED
:DUMPER,A0 (2) QUESTION: DO YOU REQUIRE TO DUMP?

We don't want to do a dump so we tell the dumper: press TAB then type "ANSWER :DUMPER,A0,NO" (or "AN 2,NO" if you don't like typing):
```
   AN 2,NO

FINISHED :DUMPER,A0 : 1 LISTFILES
EVERYTHING HAS FINISHED
    
```

Then tell EXEC to kill George: Type Control-A then DELE

^A
EXEC MESSAGE:- DELE   O.K.
Connection closed by foreign host.

Ok, George is now installed on disk, we want to start our first real session.

First boot the 7903 communications processor. On Windows it would normaly listen for telnet calls on port 23, but on Linux that would require running it as root, so I use port 2023. Also java seems to prefer ipv6 to ipv4 and, since I don't have ipv6 yet I have to set the java.net.preferIPv4Stack option. The 7903 emulator runs ok with gcj-4.4-jre-headless on Debian.
```
$ cd bin
$ java -Djava.net.preferIPv4Stack=true ICL7903 4 4 2023 7181 7903

```

Now on another terminal launch g3ee again, this time telling it to boot from disk:

$ wine g3exec.exe -d ../data -c1900 -m256 DA GEORGE3A

On another terminal use telnet to connect the operator terminal. When we are asked whether to restore say "N":

$ telnet localhost 1900

We should get a configuration report from the communications processor (unit 57)

Then when George is booted we start MOP on unit 57 by typing TAB then "MOP ON,57":

Now, from yet another terminal connect to a tty terminal with telnet:

$ telnet localhost 2023

Escape character is '^]'.



THIS IS GEORGE 3 MARK 8.67 ON 29APR10

We can now log in, for example as MANAGER. Initialy there is no password, just press enter.

When you're finished with the system you can return to the operator console and shut down the system:

That's it.
