Bits and pieces for a breadboard computer project
-
65c02 µboot, a small bootloader that provides a UI and xmodem-ish connectivity for loading apps to ram from a PC.
-
65c02 Teensy Master PCB, a level shifter to enable fast bidirectional communcation between Teensy 4.0 and the 65c02.
-
J-Modem sender, a Python-based binary transfer app
-
Teensy 65c02 coprocessor, a Teensy 4.0 program to emulate an ACIA, but much faster. With 912 MHz Teensy speed, it runs fast enough to reliably keep up with 1 MHz 65c02 clock and any amount of data throughput. Transfer speed with J-Modem sender is around 9000-10000 bytes/second.

Questions
How big is the 65c02 Teensy Master PCB?
It measures 25.4 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 65c02 Teensy Master use?
17 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 65c02 Teensy Master KiCad files?
From the jkoljo/65c02 repository on GitHub, at the commit this page was made from: the board is 65c02 Teensy Master PCB/65c02 Teensy Master.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 65c02 Teensy Master design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
