The lesson for today is that when you are bringing up a new design that you should check basic things like the clock frequency early on in the process.
Also learned that a 10MHz #Z80 clocked at 30MHz is unstable.
Currently finished this little experiment. Next step: translate it to machine code as we did in the 80s and use it to test my hex loader
Website update.
More videos and community links added to my site covering the hardware I've produced for #RC2014 and compatibles.

Cidco MailStation 作為 Z80 開發平臺
➤ 將過時的電子郵件終端機變身為 Z80 開發利器
✤ https://jcs.org/2019/05/03/mailstation
這篇文章描述了 Cidco MailStation,一款 2000 年代早期販售的專用電子郵件終端機,如何成為一個獨特的 Z80 開發平臺。儘管其原始的 POP3 電子郵件功能已過時,但其整合的 LCD 螢幕、全鍵盤和內部數據機使其成為一個具有吸引力的硬體平臺。作者分享了他購買多個 MailStation 並成功開發軟體,使其能透過數據機存取 BBS 或透過平行埠連接到 Unix 系統的經驗。文章詳細介紹了硬體規格、程式碼載入方式、開發環境,以及作者如何利用現有資源和自行開發的工具(如 USB 加載器和 WiFiStation)來進行 Z80 編程。
+ 哇,真有趣!沒想到這麼舊的設備還可以拿來玩,而且還能開發程式,感覺很有挑戰性。
+ 這篇文章寫得真詳細,讓我對 Cidco MailStation 產生了興趣,想找一臺來試試看。

Cidco MailStation as a Z80 Development Platform
Wooo, first Rust macro written...things continue to progress. Still need to figure out exactly how I want to represent the `F` register though.
It looks like I'm getting some results after all
What do you do this Sunday? Me some Z80 ASM
So while the Z80 project on Rust is going very, very slowly, the Python side is going pretty well. Got all of the registers and flags implementations mostly done including 16-bit register swaps (EX) and full prime swapping (EXX). Using `enum.IntFlag` to set/clear flags in the F register as well which helps with legibility.
Okay, not 100% satisfied over the Z80 flags implementation, but works perfectly well and mirrors what the CPU is doing. Used `mem::swap` to switch between the normal and "prime" set of flags and works exactly as expected. Things progress...
So, making slow progress as I learn `rust` things. Instead of going with my usual `union`/`struct` combination in C, I'm resorting to not overflowing/underflowing primitive types and doing things more safely. This snippet of code took far longer than it should've, but it gets the job done.
Alright, change of plans. I _could_ implement the interrupts for the MOS6502 project...or I could start work on a Z80 emulator. I mean, the docs for the Z80 are so damned good and it would be fun to learn about another CPU. I think it's time.
