Retrochallenge Initial Thoughts

I recently wrote how I’d managed to acquire some classic Level 9 and Infocom text adventures that would run on my Epson PX-8.  I’ve always been a great fan of interactive fiction (IF) and some years ago I remember spending many hours writing a Star Trek themed adventure using The Quill on my Commodore 64.  As with most of my projects it showed great promise but was never finished.

I’d quite like therefore to make another attempt at such a project although I’m not sure I’m going to be able to shoehorn this in as a genuine Retrochallenge project.  Short of writing the whole thing in BASIC, which given my ham-fisted, clunky approach to coding isn’t going to happen, I’m not sure how much development will actually involve a retro machine.

Ideally I’d like to produce a game that can be played on a variety of retro platforms providing they have a Z-Machine interpreter, somewhat unfortunately one of the few platforms I don’t seem to able to find an interpreter for is CP/M.  There are a number of solutions out there for creating IF, this morning I had a quick play with Inform7 which uses a natural language approach to building your game.  I was able to quickly knock up a few rooms and objects but the system soon had me scratching my head when I tried to create anything complex.  Also, having created only a few rooms, objects and descriptions the game file was already too large for the PX-8.

I’ve decided to base the game on the 1972 film Silent Running which in my view is one of the all time great Science Fiction films, so I settled down to watch it this afternoon and used the PX-8 to write some initial room descriptions.   I’ll have another play with Inform but given the file size issue it looks as though I’m going to need another solution if this thing is ever going to run on the PX-8, either that or stick to a two or three room adventure.

Kim Kimberley, Zork & CP/M

I had a spare hour or so today and decided to hunt around for some games for my PX-8.  Given the limitations of the display and my own fondness for interactive fiction I decided to see what text adventure games I could find for CP/M.

A quick search for CP/M games took me immediately to the Retroarchive where I’m pleased to say the first three games of Infocom’s excellent Zork series were to be found along with a number of other games.

Pleased with this result I wondered if there were any CP/M versions of Level 9’s adventure games out there and I quickly found Snowball and Lords Of Time here.

Annoyingly my plans for a bridge machine with both USB and network support remain exactly that, plans, for some reason Filink will not run on the Pentium III under DOS and I have therefore been forced to resort to my Fujitsu in order to transfer files to the PX-8.  The downside of this is I have to burn a CD every time that I want to transfer files downloaded with my Mac on the Fujitsu for transfer to the Epson.

Nevertheless I was soon transferring the games I had downloaded with Filink from the Fujitsu directly on 5.25 floppies via the PX-8 (picture below.)

All of the Infocom and Level 9 games appear to be working fine.  Some of the location descriptions are too long for the PX-8 to display without some of the text scrolling out of view and if I’m honest the LCD on the Epson is not one of the best I’ve seen, in fact the PX-4 has a much better screen with clearer better contrast.

However the keyboard is a joy to use, it has that lovely clackety clack that you don’t seem to get with modern day equivalents so I shall get stuck in again to the world of Zork and see what I can remember.

I’ve copied Zork 1 to the ram disk and will store my save games on cassette for the shear hell of it.

I am indeed standing in an open field west of a white house, with a boarded front door. Maximum verbosity.

That reminds me, I’m sure there was a another version on the Vic 20 called The Colonel’s House?  Oh, and I’ve also discovered that you can play Zork in your browser at ifiction.org.

Video Of Bomber On The Atari Portfolio

Using my recently acquired parallel port interface for the Atari Portfolio I’ve been successfully transferring files onto the Portfolio from my Windows 95 box.  Initially the process would not work, however after setting the parallel port to Auto in the PC’s BIOS, transfers worked perfectly.

I’ve been trying a number of games and utilities, one that caught my eye was Bomber by Jaraslav Janda as it’s a version of the game Blitz (which was probably a version of the original) which was the first game I bought for my Vic 20 back in 1983/84.  I shot some video with my iPhone of me playing it, badly:-

Following my previous blog entry regarding printing on the Portfolio with the Epson P-40 portable thermal printer I’ve also now made a video:-
