A Macintosh front end for modern coding agents
The old Mac is not a prop.
It is where you work.
1986ai connects flatmac on System 6 to TimeWarp on a modern Mac. Send a request, watch the work, browse the project, and bring finished Macintosh software back across the network.
The signal path
Four decades.
One local connection.
flatmac discovers TimeWarp on your network. TimeWarp translates the coding agent's structured events into a compact protocol the Macintosh can draw and navigate.

What reaches the Macintosh
More than a chat window.
The interface stays native to the machine while the useful work happens on the host.
Fix the redraw bug in Desk Clock.
I found the stale update region. I'm changing the event loop now.

A short parts list
The actual hardware.
No browser runs on the Plus. No model is squeezed into one megabyte of RAM. The Macintosh draws a purpose-built client; the modern Mac handles the provider and files.
