C204 & the PLA
Posted: Mon Aug 07, 2017 1:32 am
Hello,
I am testing a few PLAs on "black screen" boards just for the experience. I have the PLAnkton, which I favor, and the PLAtinum. I use the PLAnkton in my personal C64 since I don't need to add C204 to the board (250407). My question is in reference to the other one, and specifically C204 which is shipped with it.
I've noticed in the schematics for artwork 251138, C204 is between pin 15 of the RAMs (U9-U12 & U21-U24) and Ground. The instructions for the PLAtinum specify soldering C204 between pin 15 of the RAMs and +5V pin 8 of the RAMs. Does it matter? I prefer to install C204 between pin 15 and Ground since it's easier (between R42 !CAS side and C41 Ground side). I can't think of a reason to prefer +5V over Ground, other than current flow theory (+ hole flow vs - electron flow).
Thank you,
