The theory of operation section makes it quite clear that its all discrete logic doing the row/column counting and character decoding. For some reason, I thought that the ADM3 was microprocessor based. I guess I never really looked that carefully inside! I have a number of terminal and graphics devices that are discrete logic and I find them interesting. I wonder how small an FPGA could be and still contain all the ADM3a discrete logic :-) -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
