Unpacking !PackDir archives on Linux

Posted on Sunday, August 18 2019

!PackDir IconWhile wading through the heaps of data that I had recovered from my old Acorn computer machines, I found some interesting coding projects I did in the mid 1990s. I wanted to have a closer look at them and maybe even reuse some of the code. However, there was a little obstacle: I had stored almost all of my source code in non-standard archive files...

Converting Acorn Fonts to TTF

Posted on Tuesday, August 6 2019

Recently I converted a bunch of vector graphic files from my old Acorn RiscPC (mainly created with !Draw and !ArtWorks) to SVG files. The conversion was of acceptable accuracy with the exception of text objects. These where mostly garbled because they used some of the native Acorn Fonts of the time, which are not available on other platforms. So I was looking for a way to convert those fonts into a format that can be used on my Linux system...

Decoding Acorn BBC Basic Files

Posted on Sunday, June 23 2019

During my archeologic expedition into ancient computer stuff, I encountered a bunch of old BBC BASIC programs I'd written on my Acorn Archimedes A5000 computer in the early 1990s. For the sake of reminiscence, I wanted to have a look at them, but was thwarted by the fact that they are stored in a tokenized format that is not directly readable. So I did some research on the format and created a converter...

Emulating an Acorn Archimedes A5000 computer

Posted on Sunday, January 27 2019

Back in 1992 I bought my first Acorn Archimedes computer, an Acorn A5000 running the RISC OS 3.11 operating system. I still have this machine around, but unfortunately it is not in working condition. Luckily you can emulate all sorts of older computer systems these days, and the same holds true for the Archimedes. So if you are fond of some nostalgic feelings, let's go...

Replacing the battery of my Samsung Galaxy Tab 2

Posted on Friday, January 18 2019

Recently, the battery of my trusty old Samsung Galaxy Tab 2 (GT-P5100) has become weaker and charging cycles took longer. Buy a new tablet? Of course not! If you check your favorite video platform, you will find plenty of videos, showing you how easy it is to replace the internal battery. So let's go ahead...

RISC PC Battery replacement

Posted on Saturday, January 12 2019

As you may have seen from my previous posts, I am currently tinkering with my old Acorn RISC PC. Yesterday I was in for an unpleasant surprise when I disassembled the whole machine in order to clean it from the dust...

Transferring Data from the Risc PC

Posted on Monday, January 7 2019

During the holiday season I was retrieving numerous files from my old Acorn Risc PC in order to convert and use them on my Linux notebook. Part of this effort has been to move the files between systems, partly detouring them through my Raspberry Pi which I am running the most recent version of RISC OS on. As it turned out, the easiest way to access the data on the Risc PC's hard disc is to use an IDE-USB adapter attached to the Raspberry Pi running RISC OS...

Do not trust your old diskettes

Posted on Saturday, January 5 2019

During the holiday season I found some time to dig through my old computer equipment, mainly because I was looking for some old data that was stored on my Acorn RISC PC. I was lucky and found what I was looking for, but transfering the data to my current computer was a bit more challenging...
