This page is an example for how an exhibition in this wiki could look like. The Busch 2090 and the Nibbler won't be presented at VCFB 2020!
You will find me and my devices at my virtual BBB exhibition desk [VIA THIS LINK - TO BE INSERTED] at the times indicated below. During those times I will give an overview of my projects. During the 'normal' presence times I will be available for questions, discussions and 'coffee talk'.

Just use Chrome or Firefox and click on the link above to join me at my virtual desk. No software installation is required.
I will be available at the indicated times and can show additional images and background information. By using the 'screen sharing' function I can demonstrate the Raspberry-Pi emulation of a cassette recorder, which I use to transfer programs to and from the Busch 2090. Apart from that I will use this function to demonstrate the assembler and the simulator for the Nibbler.
In addition I will use a smartphone as a video camera to present my devices. The smartphone is mounted on a small tripod so I can move in closely and give live demos.
At the beginning of the 1980's 'experimental computers' and kits were very popular to introduce computing to teenagers and grown-ups alike. The Busch 2090 introduced in 1981 was one of those devices and was based on the TMS-1600, a 4-Bit CPU by Texas Instruments. This device will be shown together with a tape emulator and PC-Cross assembler. 4-Bit computers are ideal to understand the interaction between the arithmetic logic unit (ALU), the control unit (CU), registers, memory, etc., as the simplicity of a 4-bit architecture makes it easy to explore the system not only theoretically but also in practice.
