-===== The History of Open Source Software ===== +===== Opening Event ===== 
-What exactly is 'Open Source'? What differentiates 'Open Source' from 'Closed Source', which one came first and what is the significance of open source for the development of computers until today? What motivated developers in the early days to participate in open source projects? How were open source projects organized and why were they successful? Which specific challenges did open source present? What can we learn from open source projects of the past for the future and perhaps generally for new forms of collaboration? This talk will discuss all these questions based on historic examples like the GNU project.+Welcome, information on the festival.

 +===== DOjS – Javascript on MS-DOS ===== 
 +DOjS is an integrated development and execution system for Javascript programs on MS-DOS. In addition to the built-in text editor, the system offers an interface to hardware that is typically found in DOS-PCs, such as SVGA graphics cards, mice, keyboards, sound cards and even 3D Voodoo graphics accelerator cards. While the primary development focus is the creation of electronic art, the system can also be used for game development and is intended for beginners and advanced programmers alike.

-===== Guided Tour of the Computer Museum Oldenburg ===== +===== Charles Babbage's Analytical Engine ===== 
-We will offer an insight into our exhibition and depot of our museum and report how a private collection became a museum. The OCM was founded in 2008 and exhibits computer systems, game consoles and arcade systems from the 1970's, 80's and 90's.+Already in the 1840s Charles Babbage designed a maschine that included almost all significant element of today's computer systems. In doing so, he was ahead of its time by incredible 100 years. Unfortunately, the Analytical Engine remained a theoretical concept and could never be implemented. In this presentation we first illuminate Charles Babbage the person and will then talk about the history of his theoretical machine. Afterwards, we will the function of the machine in detail. Finally, we will report on the ambitious "Plan 2B". In it our English colleagues will try to implement the Analytical Engine for its 200. anniversary using Charles Babbage's original notes. The presentation was originally recorded for the VCFe 2020 which was unfortunately cancelled.

 +===== Analysis and Repair of a Z80 System Found in a Dumpster ===== 
 +Recently, I found a minimal Z80 system in a dumpster which was obviously a wire wrap prototype board. Obviously, the system did not work anymore. Based on the integrated circuits on the board assumptions are made what the system can do and which operating voltages are required. Furthermore the EEPROM will be read and disassembled and the glue logic will be analyzed to generate a rough memory map. Based on this a systematic error search will be done with a Hameg oscilloscope of the time. We will search for defect IC outputs, short circuits between connections and many other things that can happen as well.

-===== Disk Drives on the Example of the Commodore 1541 ===== +===== The 'Computertruhe' introduces themselves ===== 
-Disk drives and disks were an important part of the early personal computing era. This talk focuses on the disk technology of the 5.25" disk drive "Commodore 1541", known as 'the disk drive for the Commodore 64'. After a historical classification (tape drives, disk platters, 8 inch disk drives) I will discuss the structure of drives and disks, the low level recording format (tracks, sectors, SYNC markers, GRC coding) and their implementation in the drive's firmware. This is followed by a discussion of the file system format and the data transmission between the drive and the C64. We will also discuss fast loaders, which replace the drive's firmware with optimized code to read data, as well as copy protection systems, that combined non-standardized formats with obfuscated read routines. And finally we will discuss solutions to read data from old disks without errors with modern hardware.+Computers are natural companions in our everyday lives. We use them to communicate with each other, for education, for entertainment but also to engage in society and politics. In their free time, the members of our association help people with a low income or who are in financial difficulties to get access to these possibilities.

-===== Pong and the Forgotten Atari Hardware Games ===== +===== The Virtual Machine Architecture of "Infernal Runner" ===== 
-Released in 1972, Pong was the first commercially successful video game. In the time it took for hardware video games to be superseded by computer technology, Atari released a number of video games with very interesting and teachable circuitry. This presentation will cover the Pong, Space Race, Pong Doubles, Rebound and Quadrapong devices and will look at replica production, regeneration of original circuit boards, partial replicas and historically interesting components. The hardware will be shown and demonstrated live, supported by video, images and documentation.+In 1991, the famous game "Another World" was published for the Commodore Amiga. It achieved cult status mainly for its visionary art style. But also technically it was quite interesting, as it was based on a game-specific bytecode language executed by a virtual machine interpreter. Eric Chahi, the author of "Another World", six years earlier had written the game "Infernal Runner" on the Amstrad CPC. The game, published by the French company Loriciels, was rated fairly mediocre by the press, was rather simple, and also still had some bugs. Nonetheless, the game is cool from a software architectural point of view. Like "Another World", it is largely not written as a conventional Z80 program, but in a specifically designed bytecode language. This language is interpreted by a virtual machine supporting "parallel" execution of up to 255 tasks by a simple multitasking scheduler. This nice concurrency feature enabled a very elegant design of the various enemies and animated game levels. The talk will cover the essentials of this bytecode language, the virtual machine interpreter, and the process scheduler. Some code examples from the game will be shown, as well as a port of the virtual machine to JavaScript to make the game playable in a web browser. The talk tries to also give you some insights into the reverse engineering process and how much fun this was.

This nice concurrency feature enabled a very elegant design of the various enemies and animated game levels. The talk will cover the essentials of this bytecode language, the virtual machine interpreter, and the process scheduler. Some code examples from the game will be shown, as well as a port of the virtual machine to JavaScript to make the game playable in a web browser. The talk tries to also give you some insights into the reverse engineering process and how much fun this was.+

-//Norbert Kehrer//+===== Pong and the Forgotten Atari Hardware Games ===== 
 +Released in 1972, Pong was the first commercially successful video game. In the time it took for hardware video games to be superseded by computer technology, Atari released a number of video games with very interesting and teachable circuitry. This presentation will cover the Pong, Space Race, Pong Doubles, Rebound and Quadrapong devices and will look at replica production, regeneration of original circuit boards, partial replicas and historically interesting components. The hardware will be shown and demonstrated live, supported by video, images and documentation.

-===== Charles Babbage's Analytical Engine ===== +//Wolfgang Nake//
-Already in the 1840s Charles Babbage designed a maschine that included almost all significant element of today's computer systems. In doing so, he was ahead of its time by incredible 100 years. Unfortunately, the Analytical Engine remained a theoretical concept and could never be implemented. In this presentation we first illuminate Charles Babbage the person and will then talk about the history of his theoretical machine. Afterwards, we will the function of the machine in detail. Finally, we will report on the ambitious "Plan 2B". In it our English colleagues will try to implement the Analytical Engine for its 200. anniversary using Charles Babbage's original notes. The presentation was originally recorded for the VCFe 2020 which was unfortunately cancelled.+

-===== Technology Museums and Collectors: A Q&A Session ===== +===== Retro-Forth Crash Course ===== 
-There is a time when technology collectors ask themselves if their collections should serve a higher goal than just their own interests. Museums exist and is it not their goal to inform and educate the public? One could donate the collection to a museum, they surely must be happy to at least get the rare artifacts!? This Q&A session focuses on this subject and tries to answer how museums collect and which possibilities exist for collectors to be useful for a museum. The talk will be organized as an interactive question and answer session in which the moderator and the public can ask questions to the participating curators from a number of museums.+This workshop introduces the Forth programming language based on a Forth-83 system (VolksForth, Forth for the people). For the C64, Atari ST, Atari 8-Bit, CP/M, Schneider CPC, Apple 2, Apple 1, MS-DOS. Other Forth-38 or ANSI-Forth systems are also possible. We will not look at FIG-Forth or Forth-79. The workshop explains the first steps with a computer and a Forth-83 system and we will develop a small application. No prior knowledge is necessary. To participate, a retro computer with a Forth-83 system is required. Alternatively, an online CP/M emulator [[https://www.tramm.li/i8080/|www.tramm.li/i8080]] can be used. Max. 20 participants.
