<munch> Has anyone successfully brought up hack on a PDP-11/44? A first glance it seems like hack is way too big. Is it worth my time to try to squeeze in on? edward ...cbosgd!hasmed!qusavx!ukma!edward

Is >it worth my time to try to squeeze in on? It is not impossible; I have had a 11/44 version long ago. You'll have to start by throwing out vaults&guards, options, news, help, engravings, tracking properties of monsters, the choice of character at the beginning of the game, the tombstone, the camera, the scroll of punishment and all references to ball and chain, the icebox, the whistles and magic whistles, the commands 'a','o','=',')','[','/','\\','?'; if that is not enough (and it won't be) throw away all mention of gems, the special treatment of unicorns, the long worms (in the lincolnsudbury version 'w' was a wumpus - restore that situation), the wand of wishing together with the routines that parse a typed in object name, the wizard mode, the ring of warning. Throw away the routine docorner, and let inventories be given one item a time at the topline. Trim down the routines in topl.c. Omit the possibility to ask for repetition of recent messages. By now it should almost fit, and throwing away a few other small things you should be able to make it work. It is a lot of work. By the way, if I remember correctly (but this might have been on an 11/45) it is not enough to have the program down to precisely 64K, because some bug in loader or kernel will still prevent it from running. It should be 64K minus 64 bytes.

It should be >64K minus 64 bytes. In fact, I have got this version lying around somewhere. I got this years from somebody at mcvax. (This must have been Andries Brouwer, but I'm not sure) There is lot of difference between this old version and the new version. The main differences are described above (the things you had to remove). Some other features are added, like graveyards, swamps and an own implementation of vaults. If anyone is interested, I'll send him/her a copy. Have fun and good Hacking! Michiel Huisjes. {seismo|decvax|philabs}!mcvax!vu44!botter!ark!huisjes P.S. I don't know if these sources have a copyright. They did not have it, when I got them.

I have hack running on a PDP-11/44 running 2.9bsd. 2.9bsd has a new feature that allows programs to be overlaied (I think maybe someone has tried to put this feature in V7, also). Anyways, the whole program is roughly over 220KB (34K of it which is the data, leaving around 25K to 30K for run-time allocation, the highest the data segment has gotten was around 45K at run-time).
