I'm implementing an Intel 8284a clock oscillator chip in async Rust. Idea: clock + its listeners run in separate Tokio tasks for parallelism; the clock waits for listeners to finish before its next tick. My first version using Tokio channels maxes out at a 35kHz crystal. A bit less than 14MHz 😅

A few weeks ago I stumbled upon a post by Paul Rickards (https://mastodon.social/@paulrickards/110153034470766163) about a device he makes. It's a WiFi card that pretends to be a Hayes modem over an RS-232 serial connection. In unrelated news, I have poor self-control, and a USB-to-serial cable.

Hello Bluesky! @str4d.xyz here. I hope you're all having a pleasant morning 😊 Okay, what is this account about? Well, I've been looking for a hardware project for a while (wanting to get back into soldering), and decided I want to build an IBM 5150 clone.
