Having Fun With Jet Set Willy II

Introduction

This article like many others I will be doing, is a recreation, tidy up, etc of articles originally

published in old User Group Magazines. As the quality of these old magazines is quite

poor, I decided to take it upon myself to recreate those articles and present them in an

improved format, with pictorial enhancements and where possible improved content.

This time for a change from the technical articles, I thought I would have some fun with Jet

Set Willy II. This article was originally Published in Einstein Monthly News as part of their

Harry the Hacker series of articles.

First discovering the names of the rooms

Insert the JSW II disk and from DOS type;

LOAD JSW2.COM and press ENTER

MOS and press ENTER

T 1000 99FF and press ENTER

Now on the right hand side of the screen you will see the names of the rooms.

Second the Wine Cellar

The Wine Cellar (bottom right hand within the game) leads through quite a number of

rooms, but the passage to get to them is quite hard, especially THE FORGOTTEN ABBEY.

So here are some code mods to make your passage a bit easier.

Insert the JSW II disk and from DOS type;

LOAD JSW2.COM and press ENTER ;You will get the reply 202 Blocks note the

number of Blocks will be used when

saving the program

MOS and press ENTER

(Note: the dot in the next few lines is important as it marks the end of the change)

M 1CBB 00. and press ENTER ; This is the Wine Cellar

M 1F3C 00. and press ENTER ; This is the Forgotten Abbey

M 22B5 00. and press ENTER ; This is the Trip Switch

M 2401 00. and press ENTER ; This is the Crypt

You can now save the modified program by typing

Y and press ENTER

SAVE 202 JSW3.COM and press ENTER ;note the 202 should be the number

of Blocks noted for saving earlier

Now if you run JSW3.COM and go straight to the WINE CELLAR you fill find ……… well I

wont spoil the surprise.

Happy gaming.

I’ve worked in the finance sector since the late 1980s, but my passion for computing began much earlier. I purchased my first home computer in 1982, and from that moment I knew technology was what I truly wanted to pursue. So, when the opportunity arose in the 1990s to transition my career into the Financial IT sector, I seized it with both hands. Throughout my later career, I had the privilege of working on leading-edge IT projects and was eventually invited to become a member of the British Computer Society, earning Chartered Information Technology Professional (CITP) status—a charter I’m proud to still hold today. Despite my professional focus, I never lost my enthusiasm for the home computing scene. Over the years, I’ve owned nearly every major machine released in the UK. It was no surprise, then, that when MAME introduced support for vintage computers (initially through MESS), I jumped right in. Now retired, my love for 1980s and 1990s computers remains as strong as ever. When the opportunity arose to purchase an Einstein TC-01, I couldn’t resist. The seller—Adam Groome—shared a deep passion for keeping the Einstein alive, and his enthusiasm quickly drew me into the community. Today, I’m involved in several Einstein-related projects, including work on the Speculator, TK-02, and Silicon Disk hardware. In addition to these, I founded the Einstein Document Preservation Project, which focuses on high-resolution rescanning, restoration, and enhancement of all Einstein documentation. I’m also engaged in a large-scale initiative to support and preserve the Einstein’s software library.
