I wanted square pixels, which meant raising the clock speed from 6.5 to 7.375 MHz. Which added enough room for 40-column text. So I did it.
Runs the user interface for a power amplifier and essentially an analogue multiplexer with volume control chips. It can the internal application code and become the front panel for other products!
Current hobby project is getting various processor boards running on the STEbus. Mostly from a company I worked for 1986-1990, but I'm also designing a new board with the 65C02 running BBC BASIC at 8MHz.
Interfaces CANbus to a valve controller block. The customer expected a tiny bit of test code, but I had cheekily designed it to support BASIC. :-)
Interfaces servo controller commands (on RS485) with a fieldbus protocol card. It worked great!
I taught myself VHDL with the Xilinx Web pack in 2001. Started off blinking an LED, and ended up here. See http://www.acornatom.nl/sites/fpga/acorn_atom_project.htm
