Good news:
Memory #1
I figured out how to manually program a (simpler) RAM in my simulator, thanks to youtube and a couple of google searches, staying late last night. This was the easiest.
The most important thing for me, is repetition. If I am not repeating some new stuff enough multiple times, I forget it's head and its end in a very short time. If I make it a routine, for awhile, it is impregnating in my brain and I hardly forget it. I moved relatively quickly with these RAM chips
now, because I did these things some years ago, once or twice, but not doing it again consistently or repeatedly, I forget everything. Well, something remained because I moved and recognized relatively easy now what to concentrate over and I work it out somewhat fast. But I helped myself from youtube as I said. Im happy I managed to make it work in the end.
I still have problems writing and loading a *.bin or a *.hex file into the simulation chip. THe content of these files is a mystery for me. I dont think I ever did it like this. So this is brand new and very important to figure out. So far I had no luck. If anyone who is reading these things know how to do it, please advise me. I will ask on other forums as well.
