Yerzmyey. . I make chiptunes on ZX Spectrum computer since 1989. Its AY chip offers 4-bit sound, 3 channels + white noise generator, square wave and several 'buzzers'. Or 3 channels of 4-bit digital sound, but then I have to fit all samples in 48Kb of RAM. :) My other machines: Amiga 500, Amiga 1200, Atari Falcon 030, NES/Famicom, Raspberry Pi and others. The bands I founded: AY-RIDERS and also YM-DIGITAL.

Floppyshop was one of the largest and best-known public domain libraries (PDLs) in the UK - a mail-order institution that supplied Atari ST and Falcon users with disk after disk of games, demos, utilities, music, fonts and art, long before broadband made everything a click away. For countless Atari owners, the Floppyshop catalogue was how you discovered new software. Collections like this usually meet a sad end: boxed up, shelved, turned into shelf-ornaments and slowly forgotten. I didn't want that to happen here. So my girlfriend and I spent many days painstakingly reorganising the entire Floppyshop Gold series into a fully online, searchable database - every disk catalogued, every file downloadable, and all of it completely free to browse and grab. Thousands of programs and PD titles, preserved and back within reach. It's all sorted into easy-to-browse sections: Art and Graphics, Astrology, Clip Art, Communication, Demos, Disk Magazines, Educational, Fonts, Games, Programming, MIDI, Music, Product Demos, Sound, Utilities and Word Processing. Buried in among it are plenty of "lost" programs - tools and titles that are still genuinely useful today, not just curiosities.

https://zest.sector1.fr/about/

What is zeST zeST is a project for re-creating an Atari ST on top of a FPGA platform. It is a free and open-source project, available under the GPLv3 license. Features It aims to achieve fairly good cycle accuracy, thanks to Ijor’s fx68k cycle-accurate implementation of the MC68000 processor. It was developed in order to run on top of the popular Xilinx Zynq-7000 family of FPGA-based SoCs, even though it should not be too difficult to port it to other hardware.
