This is part of a thread from alt.sys.pdp10, between March 26 and 30, 2002.
Poster "Xs" is building a 350-pointer on the PDP-10.
Rich Alderson (whom I've managed to contact) claims that David Long produced
a 500-point version before his 501-point version. He also hints that there
may have been a Balrog before it became a Wumpus; or possibly just that
thematically it *should* have been a Balrog, but Long didn't want to fight
the Tolkien estate on the subject.

Well, I'm working on the PDP-10 original adventure. :)
I'm confused over what was the definitive original version,
so I wonder how many different copies got out in the old days.
So far, I found two.
http://forums.delphiforums.com/n/mb/message.asp?webtag=xyzzy&msg=175.1
adv350-pdp10.tar.gz and
ftp://ftp.ifarchive.org/if-archive/games/source/advent-original.tar.gz
The ifarchive site also has the adv350-pdp10.tar.gz file.
After studying both, the adv350 version looks like clean PDP-10 fortran.
The adv-orig seems to be a slightly earlier version, with what might be some
left over bugs, and a number of typographical errors left in the code
and text database. Also, adv-orig seems it might have some "damage". Namely,
the code was changed to avoid compiler warnings. And lower cased strings
that probably should have been left as upper case strings, consistent with
the text db.
So, I built the adv350. Here is the build guide:
SIMH 2.9-2
TOPS-10 V7.04
FORTRAN-10 Version 11 Field-Test Tape 3
Copy the adventure files, via tape drive, into the emulator.
Use the backwr utility by Johnny Eriksson
ftp://ftp.stacken.kth.se/pub/pdp10/backwr.tar
In UNIX, ./backwr -cATf adv.tap adven.dat adven.f4 advn2.f4
creates the tape file.
Use the BACKUP utility in TOPS-10 to load the files.
.dir
ADVEN DAT 90 <055> 16-Apr-91 DSKB: [100,100,ADV1]
ADVEN F4 102 <055> 16-Apr-91
ADVN2 F4 32 <055> 16-Apr-91
Total of 224 blocks in 3 files on DSKB: [100,100,ADV1]
.
Create file IFILE.F4 containing the following. If anyone
knows what the IFILE library call is officially supposed to be, I'd
like to know.
.type ifile.f4
SUBROUTINE IFILE(UNUM,FNAME)
IMPLICIT INTEGER(A-Z)
DIMENSION FNAME(2)
OPEN(UNIT=UNUM,NAME=FNAME,ACCESS='SEQIN')
RETURN
END
.
Make copy of ADVENT.DAT as TEXT.DAT
.copy TEXT.DAT=ADVENT.DAT
Edit TEXT.DAT. Change the first <tab> character in lines containing
strings that begin with white space. Change the <tab> into a comma ",".
Without this change, advent, while loading, discards tabs and spaces in
strings that begin with them. I'm not sure why this happens. Maybe it is
fortran library version specific. Three lines in TEXT.DAT require this
change. They are:
1 - - -
82 --- POOF!! ---
130 "THIS EXIT IS CLOSED. PLEASE LEAVE VIA MAIN OFFICE."
Now, the directory contents:
.dir
ADVEN DAT 90 <055> 16-Apr-91 DSKB: [100,100,ADV1]
ADVEN F4 102 <055> 16-Apr-91
ADVN2 F4 32 <055> 16-Apr-91
IFILE F4 1 <057> 26-Mar-02
TEXT DAT 90 <057> 26-Mar-02
Total of 315 blocks in 5 files on DSKB: [100,100,ADV1]
.
The quick way to compile and run is to use the following
command:
.exec adven,advn2,ifile
The step by step way to compile and link is:
.r fortra
*adven=adven.f4
*advn2=advn2.f4
*ifile=ifile.f4
IFILE
*^Z
.r link
*ainit/save=adven,advn2,ifile/go
EXIT
.
Now run ainit to initialize, then then save the core as the real advent
executable:
.run ainit

Other notes. The date/time computation code in advent is y2k compatible in
a strange way. When calling the fortran library function, CALL DATE(DAT),
the returned string is "26-MAR-:2". Advent correctly converts ":2" text
to the value 102.

I just recovered my port of Advent to the Primefrom 9-track. However,
ISTR my changes were totally confined to the separate interface
modules, leaving the ADVENT1.FTN and ADVENT2.FTN modules
unchanged.
What I *don't* recall is whether I used the CDC6600 version=20
or the DEC-10 version for the port.
Should you want to compare, you'll find it at:
http://members.iglou.com/dougq/prime/advent.sfd.zip
The ADVENT1 and ADVENT2 modules lack a .FTN suffix,
leading me to suspect these were the CDC versions.

I had a look. These advent1 and advent2 modules have code
requiring a 60 or 64 bit word machine. So it isn't a version
for the PDP-10, though it does looks very similar.
In terms of the program logic, the code looks like it originated
from a version released between adv-orig and adv350-pdp. Some,
but not all, of the bugs fixes in adv-orig/adv350-pdp where present.
The text database ccfile has numerous differences probably caused by
manual transcription. Plus a bunch of deliberate text changes
including the overall file format.

Yes, this is clearly my port of the CDC 6600 version to the Prime.
The number of bits in a character and the nunber of characters
per word are definable for different machines.
I'll verify it tonight, the Prime 2455 is back up and running, and
it's on there from when I restored the tape to it two years ago.
In turn, the CDC 6000 version was ported over from the DEC-10,
but not by me...

When I ran a comparison of this against the supposed "vanilla"
version of the Woods extension of the Crowther original, most
of the changes are due to FORTRAN differences in the switch
statement, and the charsize/wordsize stuff. And, I seem to have
added additional blank comment lines to improve the readability.
That "vanillia" version to which I'm referring can be found at

The original Willy Crowther version was written for the 6600 (since he worked
for CDC, this is hardly surprising). The port went the other way, from CDC to
PDP-10, specifically SAIL. (Don Woods was still at Stanford when I left 10
years ago; he's probably retired by now.)
David Long of the University of Chicago Graduate School of Business computer
facility expanded the 350-point Woods/Crowther Adventure into a 500 (later 501)
point giant with other things besides the wellhouse on the surface, and a back
way into the caverns--all good. He was also the beggar who substituted a
Wumpus for the Balrog.

Bzzzt...thanks for playing...
Willie Crowther worked for BBN when he wrote his Adventure. And the
original was done on a PDP-10. For corroborating testimony, check out:

There are several versions created from the Colossal Cave Adventure.
