Finally I have managed to order some missing components for the Ben Eater 6502 breadboard computer.
Most importantly I have ordered a WDC 65C02, the newest CMOS version of the original MOS 6502 CPU. I have also ordered some tactile switches (push buttons). The old one was not stable enough and I have found the APEC MUTLIMEC 5G, which is quite robust, available in a through hole configuration, and the pins have a distance that is multiple of 0.1 inch, so they can be plugged into a breadboard. More precisely, the distance is 0.3 inches (7.62 mm), which is 0.1 inch (1 hole) bigger than some others I have seen in videos, but these are the ones that I could find in an online shop. The positive thing is that you can get nice button caps for them. I wish I could find some similar latching pushbutton or toggle swiches.
Two SRAMs, an EEPROM and a Versatile Interface Adapter (VIA) as well as an RS232 interface chip were in the package as well.
To be able to program and debug the setup I have also ordered an Arduino MEGA, with its 54 digital inputs I should be able to follow Ben Eater’s approach and see what’s happening on the various buses. And I can also experiment with other things using the Arduino. And I also ordered an Arduino Nano Every with headers. I just find it fascinating to have such a little board. And with the headers I can directly plug it into a breadboard.
Last, but not least, I have also ordered an LCD display. It was difficult to find one with direct interface to the controller chip. Most of them have a built-in SPI adaptor, so that it can be easily connected to a RPi or Arduino board without having to program the registers. But that’s not what I want to do.
