\begin{frame}{What's a TI-8x?}
	TI-82, TI-83, TI-84+, etc.:
	\begin{itemize}
		\item Z80 @ 6/15 MHz
		\item 24k user RAM
		\item Monochrome LCD
		\item TI-OS routines usable \\~\\
	\end{itemize}

	TI-84 CET:
	\begin{itemize}
		\item eZ80 @ 48 MHz (8/16/24-bit Z80 monster)
		\item 154k user RAM
		\item color LCD (32k color \textit{or} 16-color with palette)
	\end{itemize}
\end{frame}

\begin{frame}{Toolchains}
	\begin{description}
		\item[Assembler]: spasm (or a different Z80 assembler), spasm has an
			eZ80 mode
		\item[Wabbitsign]: to generate usable TI-8x programs
		\item[HW docs]: WikiTI\footnote{\url{https://wikiti.brandonw.net/}},
			Cemetech\footnote{\url{https://learn.cemetech.net/}}
		\item[Emulator]: TilEm2, CEmu (eZ80 CET) (need ROM dumps)
		\item[HW Loader]: TiLP (can dump ROM)
	\end{description}
\end{frame}

\begin{frame}{Hurdle: 8XP header, TI-OS}
	\begin{itemize}
		\item TI-OS routine addresses depend on version $\to$ portability hell \\~\\
		\item 76b header (including a useless 42b comment)
		\item Haven't found any tricks yet \\~\\
		\item Size on PC disk vs size in TI-OS differs: 59 bytes smaller on TI-OS
		\item I erred on the side of caution, size on disk $\le$256b. If unsure,
			ask orgas.
	\end{itemize}
\end{frame}

\begin{frame}{Graphics}
	\begin{itemize}
		\item Monochrome 92x64 LCD, slow response time
		\item No driver, you need to bit-bang data to a port to toggle pixels
		\item I stole the Ion PutSprite routine\footnote{
			\url{https://learn.cemetech.net/index.php/Z80:Sprite_Routines}} for
			my prod, go sue me
	\end{itemize}
