A sea of pixels and power

A project log for PZ1 6502 laptop

I am building a laptop with a W65C02, lots of memory, SID-sound, decent graphics and a filesystem.

More HW has arrived!

The long awaited Gameduino 3X screen has crept slowly to me from USA, and finally landed at my doorstep. It is a marvellous screen with its own GPU, and a totally different way of programming. More similar to modern 3D-accelerators, but limited to 2D.

4.3", 480x272 pixels, 24-bit colour, 1024KiB screen ram, built in fonts and 8MiB flash. WOW! The tricky part is that it really doesn't have a simple frame buffer, but instead uses commands in a display list. Takes some time to get used to.

After some frustrating manual reading and testing I've finally gotten what I want for a start: an 8x8 text-mode with back- and foreground colours and way too many sprites :) All synced at a buttery smooth 50Hz.

The screen with the Teensy 4.1 and its 8MiB PSRAM makes this emulated 6502-system extremely capable.
