Essex MUD1 by Trubshaw and Bartle
This branch is the 1986 source for MUD including both BCPL, MACRO-10, and game source files. To compile and create a working MUD on TOPS-10 with Monitor 7.04 and a working BCPL compiler in [1,4] you must do the following:
Create a PPN and directory of [2011,2776] (Richard Bartle's own PPN at Essex). The PPN must have ENQ/DEQ aloocations for MUD to work.
Place all source files from the branch in to the PPN directory
login in to PPN [2011,2776]
Type: DO MUD M
Type: DO MUD DM
Type: RU DBASE
Type: RU MUD
Providing you have enough memory (tested on a simh KS10 with 1MW and a RP06 drive), it should just work. Use Richard as your persona to gain Arch-Wiz powers.
There is still some further understanding needed as this mud86 source handles WIZ MODE differently to the mud84 tape and looks for a file that does not currently exist. Still, you can create personas and play the game.
Key differences in game between mud84 (tape) and mud86 (Stamford) version are that fireworks are a thing and I think various events like death are handled differntly so you dont need multiple dead rooms. Hence this mud86 has 420 rooms compared to 435 rooms in mud84 on the tape in the zip branch.
Full build instructions including how to set up a PDP10 with TOPS-10 using SIMH is at https://www.quentin.org.uk/tag/pdp10/
Do not mix MUD84 sources or binaries (from tape) with these MUD86 sources as they are not compatable and will fail to compile or run as expected.
I have discussed with Richard Bartle the licence for this code which he has said on 18 May 2020 can be used for a not-for-profit purpose. This means you can do pretty well what you want with it except make money, and if you give it to other people they have to follow the same restrictions."
