Datacoin - How to Etch an IBM PCx86 simulator to the Blockchain Pt 2 (Applications)

Windows Tutorial

Continuing from the previous guide your simulator should be up and running, it's now time to add some software using the links feature
included with Apertus. Links allow you to use previously etched content stored in the Apertus root index.
The following tutorial will demonstrate how to add a copy of VisiCalc, a trailblazing spreadsheet program
released for the Apple II in the late 1970's. More information on VisiCalc is available below.

1. Create a new folder called ibmapps and add the following files from your ibmjs directory

index.html
PCDOSS100.json
visicalc.json
components.css
components.xsl
example.xml

2. In your ibmapps folder, open example1.xml in notepad, scroll across and add in the following before line

This line adds the floppy disk driver component and software VisiCalc

3. You may have noticed that we didn't copy accross a few of the files from the ibmjs folder, we will be using previously eteched
copies which will help us reduce the overall publishing cost.
Soon you be able to work out those savings in VisiCalc Wink

4. Go to your main Apertus directory and open the root folder. Unless you have etched multiple times you should have only one folder
listed if not open each folder until you find the content from the previous tutorial. Click on the folder containing your files and
highlight the long string, select copy. This is the transactoinid that you will be inserting into your new files to create the link.

5. Edit example1.xml in notepad, scroll across until you find an entry for ibm-basic.1.00.json, add / then the transactionid
i.e
6bf7c945623b1571571369769285dd350832703b880fa6978cdfd08db77398d8/ibm-basic-1.00.json

Repeat for
ibm.mda-cga.json
1981-04-24.json

Edit index.html, scroll across until you find an entry for pcx86.js again add / then the transactionid

Save both files.

6. Launch your Datacoin wallet and wait for it to fully sync then open Apertus.

7. You should already have a profile setup from the previous tutorial. Select your settings then
click attach and browse to your ibmapps folder. Select all files using ctrl + a and hit ok.
Providing you have enough DTC in your wallet to complete the transaction, click etch to publish your simulation to
the blockchain.

8. On startup it will display the dos command line, to run VisiCalc simply enter B:vc (no /)

[UPDATE] The brpwser embeded into http://apertus.io has security limitations that prevent some pages from working properly. we were so excited to see this work using the shortcut method you worked out above that we decided to save you and everyone a few steps by recreating the same functionality within the browser. in the lastest release of Apertus v0.3.15-beta, you will see a new button in the top left corner of the browser window. clicking it loads whatever you are currently browsing into your default web browser.

On my Windows surface the edge browser has to be setup as my default web browser to get your example to work.

Thanks for your time.
