In this final episode I’ll show how I implemented data-exchange with my card using IRQ and the development of some ShellExtensions and ControlPanel-applets for Windows98. Fixing the SRAM Last time I had some problems with my second SRAM producing noise. It turned out, that I missed two additional lines in the documentation: besides the chip-select…
In part 2 of this series I will show my progress on developing a DIY PCI Card using Alteras FLEX10K FPGAs. Last time I reverse-engineered an old Altera development-board I’ve found on eBay. Unfortunately there was absolutely no documentation about this card so I had to track all traces on the PCB by myself. Of…
Retrocomputing with real hardware is a very nice way to understand how modern computers have learned to run and talk. I developed some GUI for OS/2 Warp 3.0 and Windows 3.11 to control some of my microcontroller-projects. Windows 3.x and the Win16-API To develop a GUI for a modern computer, you can make use of…
Plug&Play is a mystery to you? Until recently it was for me too, but let’s take a look at the PCI specifications and lift the fog of mystery about PnP. Plug&Play Christmas 1994 my family and me got the first computer: an Intel 486Dx4-100 with 16MB RAM and a 534MB harddisk-drive. The only expansion-card was…
In this episode I take you with me creating an audio mixing console based on the Arduino Vidor 4000 FPGA board. The final device has five EQs, a noise gate, an audio compressor and up to 22 channels with a total latency of 20.8 microseconds at 48kHz.
