ZK (ZK.txt)

Complete solution of the VAX/VMS text adventure ZK (1985) by Edmund Sullivan 
and William Lees. 
Updated by Tim Sneddon and released for VAX, Alpha and I64 OpenVMS systems as 
"The Halls of ZK" (2013).

This solution is for the 2013 release. As of 2020 it's still playable online at 
http://hallsofzk.org/play.html

This solution is based on a previous solution for an apparently earlier version 
of ZK at 
https://github.com/tesneddon/zk/blob/master/zk/wizardry.txt

e (petty cash office), give neon ball to officer, open door, w, look in ball, 
look in ball .... (repeat until the petty cash officer types the four-digit 
code on the safe keypad - note the number e.g. 1234 - this is a different 
randomly-generated number each play. It can take around 35 or so moves at this 
point to wait until number is revealed.), s (lobby), 
ask guard, please start building lights, n, open door, e, type 1234 (change 
1234 to the combination revealed earlier), open safe, get bills, open door, w,

drop tape

Part 3 - Obtain DTR tape
ask guard, please give keys to me,

s, e, open door, drop lamp, e, get card, open door, w, get lamp, 
w (strongly suggest saving the game at this point, as the next bit has to be 
done without any mistakes), w, start lamp (lab of implementors - this room and 
the tape library are always dark), w (tape library), stop lamp (you are bathed 
in strange light), start lamp (you are now on a critical path and must get the 
card to the VMS manager within 15 moves, or the lettering will fade - any 
mistakes on this bit and you have to start part 4 all over again), e, e, n, e, 
n (thankfully you left the door open earlier), d, s, w, n, n, w, 
give card to manager, stop lamp (you should now have the VMS tape as long as 
lettering on card had not faded - if the card was blank then you would have to 
do these steps again, but with less lamp power remaining, strongly suggest 
restoring to previous save in that case.), e, s, s, e, open door, n, u, u, 
open door, s, w, s, s (lobby) 

Part 5 - installation of tapes
ask guard, please start building lights, get CDD tape, get DTR tape, n, n, e, 
open door, n, d, d, open door, s, w, s, s (Operator’s room), get disk, n, 
start vax, open disk drive, put disk in disk drive, close disk drive, boot vax, 
examine console (boot failure, a field service rep appears), open disk drive, 
get disk, give disk to rep, wait, wait, wait (field service rep now hands you a 
formatted system disk), put disk in disk drive, close disk drive, boot vax,

Part 6 - Getting past the guard with the disk and out of ZK
Ask guard, please start building lights, e, e, e, n, open door, w (Personnel), 
say <answer> (repeat for each of the six questions, you must answer all of the
 six random questions out of twelve correctly - *note5 lists the needed 
answers), open door, e, s, w, w, w (lobby), get sack, open sack, 
put disk in sack, close sack, give keys to guard, give badge to guard, 
open door, s (or wait until thrown out of building while in possession of 
disk), open crystal door, s, s, w, w (Helipad), wait (The helicopter lands and 
you climb aboard ... You've Won! All of ZK congratulates you!)

*General notes:- Doors always automatically close behind the player when walked 
through. So typing "open door" is needed many times. Fortunately opened doors 
do stay open at least until the door is walked through, this behaviour is 
needed to solve the puzzle of getting the third tape.

As noted in the game, unambiguous words can usually be truncated to four 
letters.

*note1:- Type "examine wall" and you will see a pattern representing a 
sequence of 7-bit binary numbers where w=0 and b=1. Together, they represent a 
string of 26 ASCII characters which make up the password to open the door. 
The in-game ASCII table inside the sack is helpful to translate the pattern if 
needed, (look up "d", look up "i" ...).

*note2:- This is a single long command 
"ask guard, please start building lights" and the comma is required. Random 
rooms go dark in the building at random times as the lights get switched off 
in various places throughout the game. You always need the lantern in case this 
happens to a room you find yourself in, although the lantern power doesn’t last 
too many turns. To save lantern power for where it is really needed (in the lab 
of implementors and tape library, where it is always dark), it’s best to keep 
asking the guard to turn the lights back on, every time you pass by to minimise 
the amount of darkness in the building. The shorthand for turning the lantern 
on and off is "start lamp" and "stop lamp".

*note3:- This is the last time in the walkthrough I use "drop all". Once you 
are wearing the badge, it’s best to avoid this command since it will also drop 
the badge you are wearing. A guard periodically checks you are wearing the 
badge from a specific point onwards in the game. If you have dropped it, then 
you will get ejected from the building.

*note4:- We open the doors here in advance of needing to go through them as it 
saves moves in the critical path on taking the UV-exposed card to the VMS 
developer before the lettering fades.

*note5:- These are the answers to the questions asked by the personnel officer.
You will be asked six picked randomly from these twelve. The below answers can
be typed as-is, or as part of a sentence as long as the answer is found in it.
