Now this is very interesting. Both because SCSI2SD is a bit expensive, and because the newer V6 boards would need an adapter to hook up to an old Mac. But on the flipside while the current SCSI2SD seems pretty swell for connecting to other SCSI devices via adapters; a Raspberry Pi itself is a pretty general reusable platform.

As far as I’ve been able to figure out, old Macs have ridiculously slow SCSI buses by modern standards of any mass storage device, and I think they didn’t even support DMA until the late ‘90s. But to be fair hard drives were typically in the 10s of megabytes in the late 80s – early 90s, and a few hundred megs at the most.

Signs of a simpleton having fun with a new microcontroller:

  1. Write a program that makes the LED blink like a mother fucker.
  2. Write a program that spams a hello world to USB serial.
  3. Write a Read Eval Print Loop over USB serial.
Compared to what I’ve done in C with simpler micros like the 8051 family, I’m finding the RP2040 really damned nice. Not only because of the Cortex M0’s horse power, but because of the really nice library that comes with the Raspberry Pi Pico. For the hell of it, I decided to abuse it with some simple C++ by for the REPL just to see that C++ I/O and string handling, does in fact work.
Of course, me being me, I ended up with a really simple set of commands:

static string evalline(const string& line)
     if (line.empty())
         return “”;
     if (line == “monkey”)
         return “Willow?”;
     if (line == “monster”)
         return “Corky?”;
     if (line == “sweet”)
         return “Misty?”;
     if (line == “help”)
         return “Try nicknames with fur”;
     return string(“Unknown command: “) + line;

Because why not? 😜

Pimoroni’s New Pico Display Takes It to the Max

“Damn it, people! Stop making me want a handheld Pico that can play DooM!” — Terry Poulin upon seeing how many buttons this display has.
A reoccurring thought of late has been just how much of DooM could fit within the Pico’s memory constraints, and a practical way to handle storing the wad files externally.

Sounds like everything I found bothersome has been improved, except for trying to do any kind of serious video playback without using omxplayer.
