Frotz on Xenix

Well after having some fun with gcc, I wanted to try something a little more… “fun”. I’ve had good luck in the past with ‘dumb frotz‘ on the old BSD stuff (4.2/4.3 etc) but surprisingly I had no luck at all with gcc & xenix.

Well that was rather odd.

So in some crazed attempt I tried the regular version of Unix Frotz 2.32. Xenix was lacking the memmove procedure, but thanks to an old post here, I was able to get it running under Xenix.

Ok, fair warning it is SLOW. It’ runs the cpu into 1.0 levels… I don’t know why. My attempts at building gdb and using it from that old Soviet site hasn’t met with much luck.

Oh, and it was easier to massage some make files with gnumake.

But it does run!

If anyone want’s to give it a whirl it’s available here.

Zork lives on the Altair!

Ok, I can’t sleep so I thought I’d rummage through the dungeon of Zork…

And what better platform to do so than the Altair?

First get your altairz80.exe, out of simh, or just build it yourself…

Then you’ll need a copy of CP/M! (http://www.schorn.ch/cpm/zip/cpm2.zip)

Finally a copy of Zork (http://www.retroarchive.org/cpm/games/zork123_80.zip)

unzip everything into a directory, then run the following

C:\altair>altairz80.exe cpm2

And with any luck you’ll be greeted with the following:

Altair 8800 (Z80) simulator V3.7-1
64K CP/M Version 2.2 (SIMH ALTAIR 8800, BIOS V1.25, 2 HD, 15-Jan-07)

Just like MS-DOS right?. … Not quite. Anyways there is time to tour later, but for now there is dungeons to explore.

The Altair has two floppies (out of eight) and a 8mb hard disk!… So let’s go to the hard disk on I:

I:

changing drives is just like MS-DOS, letter, colon then hit enter. Ok now lets copy in the zork game from the native PC into the emulator. Hat’s off to Peter Schorn for this!

b:read zork1.com
b:read zork1.dat

If all goes well it’ll look like this:

A>I:
I>B:READ ZORK1.COM
READ V-2.21 (03-Dec-06) SIMH Interface V003

Read from “ZORK1.COM” and write to “ZORK1.COM”.

I>B:READ ZORK1.DAT
READ V-2.21 (03-Dec-06) SIMH Interface V003

Read from “ZORK1.DAT” and write to “ZORK1.DAT”.

Ok, now with that out of the way, lets enter the Dungeon!
