From the project

The purpose of Project Wrass is to develop the Wrass 1.

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

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.
