12:11 AM rue_mohr: runs for an hour, might take as long to recharge
02:23 PM rue_mohr: https://github.com/emilio-a/1bitCPU/blob/main/src/onebitcpu.vhd
02:25 PM polprog: youre famous now
02:25 PM polprog: Nice small code
02:25 PM rue_mohr: haha
02:25 PM rue_mohr: I cant read it yet....
02:25 PM rue_mohr: I see the basics
02:26 PM polprog: he has a dp ram for program storage and an 8 bit regiter for i guess IO?
02:26 PM polprog: idk what the shift reg is for
02:26 PM rue_mohr: yea, I'm not sure where the dual port ram comes in
02:27 PM polprog: ok, he i susing only one port
02:27 PM rue_mohr: ah, its just a hammer than
02:27 PM polprog: data_in_a is connected to the bus_pgm, data_in_b is connected to itself?
02:27 PM polprog: address_a is connected to top half od bus_pgm
02:35 PM polprog: wow he is gonna try to run it on tinytapeout
02:40 PM rue_mohr: thats his goal
02:41 PM rue_mohr: is he using the serially programmable version?
02:41 PM rue_mohr: I got the idea he was
02:48 PM polprog: i think he just took your breadboard design
02:48 PM rue_mohr: they are both on breadboard
02:48 PM rue_mohr: Salidas = IO?
02:49 PM rue_mohr: hahah which languages does who speak now? hahaha
02:49 PM polprog: salida = exit (spanish)
02:49 PM rue_mohr: ok, ok, yea, entradas is the inputs
02:50 PM rue_mohr: so, he's only breaking out two inputs and two outputs
02:52 PM rue_mohr: something seems wrong, he only has 8 address lines, it should be 10
02:53 PM rue_mohr: I have to go fix a 3 phase motor...
06:27 PM rue_mohr: what if I made an emulator that opened two pipes, one for input, one for output
