These are times where one just gets bombed with gigahertz, gigabytes. The Steckschwein is a ne 8bit computer, that wants to show, how much know how is already to be found in a rather simple computer.
Our mission is to create a computer that might have existed during the heyday of 8bit home computers. Only with more modern interfaces to the outside world, since nobody wants to fiddle with floppy disks anymore.
The name “Steckschwein” originates to the very eary stages of out project, where everything was prototyped on breadboards (german: “Steckbrett”), and we all know that those things can be real pigs.
We started off with a very small test circuit, having the 65c02 execute only NOPs, by hard wring the data lines to $EA. Then, we started to add new components step by step, such as ROM, RAM, IO interface (65c22 VIA), serial interface (UART 16550), until we arrived at the current specifications:
