Complete build of a new PICO-56 kit. The PICO-56 is a re-implementation of the HBC-56 homebrew computer on a Raspberry Pi Pico. Emulating the 65C02 CPU, TMS9918A VDP, dual AY-3-8910 PSGs. Interfacing to a VGA display, PS/2 keyboard and dual NES controllers.

PICO-56 kits have sold out in 24 hours. I'm genuinely surprised by the positive response to the PICO-56 launch videos, and figured most people would wait out the giveaway before ordering a kit. Turns out, I was wrong 😂. Thanks to everyone who has ordered their own PICO-56 - I'll be busily preparing them over the next few days. In the meantime, I encourage you to enter the giveaway and failing that, please wishlist the kit on Tindie so I have a rough idea on how many I should order for round #2. Thanks for the support 😊

You should buy some 0.35mm solder for all of your SMT pins. Also it's a really good idea to use a 0.3mm tip for soldering SMT unless you're doing a bunch of pins using a reflow technique.

@inerlogic 6 месяцев назад

@etmax1 I was going to say, that was a giant tip, and huge solder.... got the job done though

@etmax1 6 месяцев назад

@@inerlogic Yes but with the right tools it's much easier with less chance of short circuits. Another thing I do is use low melting point solder in 0,35, it flows at lower temperatures so you can set the iron temperature down to around 300C (for small pads) and there is less damage to plastic items when you accidentally brush up against them.

It's amazing what can be done with Raspberry Pico. Great video!

I like the cleanness of the design! The 12-bit color and boing ball remind me of the beloved Amiga. The audio output looks like a combined voltage divider and lowpass filter for a PWM output, -3dB cutoff frequency at 1600 Hz. I'm looking forward to seeing/hearing the demos. Cheers.

@TroySchrapel 6 месяцев назад

The boing ball was definitely inspired by the classic Amiga demo.

Great work! I just built one for myself. I wanted to thank you for making the project available. The blue PWR button is tricky, must be that exact specific type listed in the BOM, there are many versions of it coming in multiple configurations. However, since the power circuit is optional I power the board using usb power for now. Again thank you for the work!

@TroySchrapel 5 месяцев назад

Nice one. Yeah, on later revision boards, I've elongated the power button pads.

Hi the kit arrived yesterday and I got it built in an hour or so. Had a little trouble getting the SD card to cooperate but after some touch up soldering all is good. Looking forward to the videos to come and I am going back to look at the software development for the emulator and HBC-56 for details now. @@TroySchrapel

It's it possible to update to use TMS9958 or 9978 video? Even if just to add the smooth scrolling of the 9958/9978.

@TroySchrapel 4 месяца назад

I've considered doing this. It's using my own TMS9918A library, and I do want to extend it to support the 9938, 9958, etc. I don't have any real chips to test against yet though.

@winstonsmith478 6 месяцев назад

Fantastic! On one of the GitHub pages I saw mention of sprites and framebuffer. Used how? Via special BASIC commands, Python, assembly language? The Amiga bouncing ball makes this look very promising.

@TroySchrapel 6 месяцев назад

The bouncing ball and other demos are written in C. There's not much to them. The source code is in the PICO-56 repository 'examples' folder. github.com/visrealm/pico-56/tree/main/episodes/ep01-vga

@@TroySchrapel The core is expecting a USB keyboard, so code to support PS/2 would be needed.
