The second board is memory (PROM), holding microcode for the I/O Processor, which is a (very strange) computer, independent of the CPU. Each gold-lidded chip holds 2K bits in tiny metal fuses. The chip is programmed by blowing the fuse for each 1 bit, literally burning the PROM.

First board is a network interface. Each side is identical and supports two networks. The IBM hybrid module (right) contains tiny transistors, resistors, etc. to handle the analog stuff. The golden Motorola chips format bits to transmit and receive them. The other chips are mostly shift registers.

The Space Shuttle had five general-purpose computers that controlled, monitored, and navigated the Shuttle. Each computer consisted of two boxes: the CPU (right) and the I/O Processor (IOP, left). The IOP connected the computer to 24 high-speed networks. Let's look at two boards from the IOP... 1/N

After countless hours debugging, I'm very happy to announce A/UX 3.1.1 (and probably other versions) boots and seems mostly stable!

You can try it yourself in Snow bleeding edge right now! Note you _must_ set mouse emulation to 'relative' or you won't have a mouse and things will crash.

Please report any issues :)

If you run nginx, it's time to update. Some RCEs were just patched. And no, this isn't the same one from a week or two ago.

Hey #tangara friends!
For my understanding: if I wanted a custom touch wheel face plate and would also use a PCB as "material", I should not use any copper on the layers to not interfere with the EM field? Or won't it matter?
Thanks!

2.51+ releases are rolling into stores: Video/Audio Calls and Channels are not experimental but part of the default feature set now 💫

Calls and channels are always end-to-end encrypted, and only you and your contacts know each other's identity and metadata (avatars, names, keys etc.)

For calls, Delta uses a minimal Rust WebRTC turn server github.com/chatmail/chatmail-t running on hundreds of relays worldwide. It helps to establish P2P media streams, or for relaying traffic if P2P connections fail.
