その他注意点等
- 8251シリアルLSIのアドレスデコードをSBC8080 SUBボードと合わせる場合は、アドレスデコードジャンパ(J2)の1-2を短絡(I/Oアドレス:00h)してください。
- 8255パラレルI/O LSIのアドレスデコードジャンパ(J3)は 13-14を短絡(I/Oアドレス:C0h)が推奨です。

Questions
How big is the Z80-8251-PPI PCB?
It measures 100 × 74.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Z80-8251-PPI use?
44 parts, built around the 74HC4060D, 74LS139PC and 2SC1815. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Z80-8251-PPI KiCad files?
From the kuninet/Z80_IOB repository on GitHub, at the commit this page was made from: the board is KiCAD/Z80-8251-PPI.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Z80-8251-PPI design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
