Z80Manuals.zipThese are datasheets and whatnot for the stuff on the SD70 board. The SIO and PIO technical manual are put here separately just because they are so large and exceed the limits of this site. But this has most of the juicy stuff.x-zip-compressed - 24.34 MB - 06/21/2022 at 17:40 |

Zilog Z80-SIO Technical Manual.pdfyou kinda need these special manuals to get the real skinny on how these peripheral chips work -- the datasheets are just high-level details.The DART is, I guess long since discontinued, but the SIO is similar in that it does what the DART does and also some ancient synchronous protocols as well. But the register detail is important. This one is big, so I couldn't zip them all into one package. Adobe Portable Document Format - 24.10 MB - 06/21/2022 at 17:36 |
