    Hey Guys,

    Since dedicated DMA Controllers such as the Intel 8237 are obsolete and are no longer being manufactured, I propose to build one from CMOS glue logic. I know that there are quite a few left that can be bought however, I thought that I would attempt to build one. Could an effective and simple DMA Controller be built with NAND gates and octal bus transceivers?

    No -- not a practical one. You'd have a great deal more luck with an FPGA. I'll bet there is even an 8237 macro you could use
