README.mdProject Wrass
The purpose of Project Wrass is to develop the Wrass 1.
A 6502 based computer having the following specs.
- W65C02 running at 2Mhz
- Bankable RAM giving a total of approx 300KB of usable memory
- Expansion bus for up to 16 devices
Future specs:
- VGA output of 640x480 with 256 colors
- IO Card with W65C22 Vias and support for SPI
- Support for SD cards on IO card
- 8Mhz CPU clock speed
- Global scroll registers for video
- Sprites
- 3 channel sound synthesizer
Software
The 16KB ROM is bankable using an external switch. This allows the computer to run "2 sets" of software.
The existing one is a simple homebrew "monitor" giving access to simple read, write and jump commands.
Future:
Support enhanced basic

Questions
How big is the Lcd interface PCB?
It measures 140.2 × 81.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lcd interface use?
20 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 Lcd interface KiCad files?
From the nojan1/project-wrass repository on GitHub, at the commit this page was made from: the board is eda/lcd-interface/lcd-interface.kicad_pcb and its schematic eda/all-in-one-smc/address-decode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lcd interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask nojan1 before reusing the design.
