Something cool i finally managed to create correctly in Logisim that i wanted to share with you guys:
ttl V 2.circAnd it even comes with a test text file!
(see attachment)
how to use:
0. Make sure the save enable button is on.
1. select the counter number.
2. type in on your keyboard whatever address you want to start typing at (remember it!)
3. select the keyboard with the poke tool and type in whatever you want.
4. go to the address you started at
5. click the save enable button so it is at 0
6. Your text should appear on the TTL screen!
If you want to keep what you've written, just right click on the memory and select "save image". But be aware that what you've written will be saved in hexadecimal.
This is one hell of a fun circuit simulator, and there's people who've made proper computers out there already.
I highly recommend trying this stuff out.
