Today Zeme showcased his #zeST at Atari Invasion, a meeting of #Atari enthousiasts in Maarssen, the Netherlands. He played some demos including Closure, a demo that pushes the ST to its farthest limits, and the Synergy Megademo, in which he participated as […] [Original post on pouet.chapril.org]

A zeST setup on display on a table, with a LCD screen, a pair of speakers and a PC keyboard.
The zeST board is in a nice custom grey and orange 3D printed enclosure, with a zeST sticker on top. The enclosure also contains an audio output module, as we can see the speakers' jack plug connected to it.
The screen is displaying the Synergy Megademo main menu.
Next to it is a printed information sheet, with a quick description of the project and a QR-Code linking to the website.

I have implemented some undocumented quirks and glitches of the Atari ST's floppy disk controller in #zeST. It now fully supports the Union demo's copy protection. Now one can run the internal copy program and copy the demo to another floppy image file! 😅 #Atari #AtariST #FPGA #retrocomputing

A screenshot of the Union demo's copy program running in zeST. It is reading the source floppy disk.
