80C32 computer application notes:
TV test pattern generator
To enable the 80C32 generate a TV picture, it requires a digital-to-analogue converter (DAC).This DAC must be capable of working at relatively high frequencies, typically in the MHz range. Here, the DAC ts realized by an R-2R ladder network, which is far less expensive than a dedicated DAC IC. and does the job equally well.
