Re: Setup the Gigatron loader with Arduino and Python
Thanks for the write up! These help tremendously in making hacking accessible. I just updated LoaderTest.ino so that fewer edits are required: just select the configuration in the top of the file. I hope I didn't mess up. I'm somewhat puzzled why there is no prompt. Perhaps the Arduino Micro doesn't...

Re: BASIC
A first BASIC can get away with skipping quite a lot of functionality: Floating point Multi-character variable names Arrays Correct precedences for infix expressions String variables or operations (the Hackaday BASIC batch also doesn't do them) Full screen editing (just do with a line editor at the ...

Re: Keyboard hookup with minimal means (dream)
I agree that two more shift registers is not nice. The one on the board is already a little cheater. After all, software could easily sample the game controller bits during vertical pulse. The 74HC595 is rather complex because it has 16 flip-flops and a tri-state buffer. We're effectively not using ...

Registration settings updated
We got some bot spam in the forums recently (now deleted) because the default phpBB setting is that new users are automatically accepted after e-mail verification. We now changed it to admin approval.

Re: MIDI Audio:
For demo purposes at the HaD conference I made a ROM file with your MIDI-blasting tetris.gt1 in it: https://marcelk.net/2018-05-26/theloop.2.rom I put Tetris in place of Credits in the menu, and I removed Jupiter to free up ROM space. A hack in SYS_Exec_88 is also needed to accept the GT1 file, beca...

Keyboard hookup with minimal means (dream)
Nice and clear. As an inverter we can repurpose one from the clock: U1E is not really needed. In the next series its output is not even connected any longer to get a somewhat cleaner CLK1 signal. Furthermore, the DB9 allows feedthrough of more signals than are currently connected. We can also consid...

Re: MIDI Audio:
There could be more to it than just aliasing. The reduction from 8 bits accumulated to 4 bits out induces a discretisation error. It might be better to carry over the remainder of this truncation to the next sample, instead of resetting it. Well, all speculation and much tweaking potential.
