Maybe someone can help me solve a few small problems I'm coming across. I'm following this schematic/description -- https://gamesx.com/controldata/psxcont/psxcont.htm#CIRCUIT I think I figured it out...mostly. He leaves a lot to be deciphered, lol. I'm drawing up a schematic in KiCAD right now, and I only have a few questions: 1. The DATA pin of the controller plug connects to SER OUT, correct? 2. Where does the COMMAND pin of the controller plug connect to? I must've re-read the entire page 15 times and still can't decipher where COMMAND goes. 3. Are the 74HC165 pins not associated with buttons (A1-A8, B1-B8, etc.) left with no connection? Or do they share a connection? COMMAND, maybe? Thanks in advance!
Hello there, I am building a 1200Xl from scratch. On the motherboard there are what appear to be decoupling capacitors that are located between pin 8 and pin 16 on the memory chip. C16 - C23 I am wanting to install gold plated machine pin sockets that come with a decoupling capacitor installed in the frame of the socket. The Atari schematic calls out 0.1uF on the motherboard. The Capactor in the frame is also 0.1uF That would give 0.2uF per memory chip if I installed the caps in the board. Do I just replace the caps on the MB with wire, omit them entirely or leave the caps in the motherboard? Thank You Douglasmemdetail.bmp
