Adds a software-controlled FM receiver to a Commodore 64 or 128 through the user port, with an optional real-time clock and station storage.

Protovision showed eight units in stock with a one- to two-week shipping estimate on 2026-07-29. The optional DS3231 module and its CR2032 or LIR2032 battery are not included. The seller says the supplied software is incompatible with SD2IEC and similar devices and strongly recommends an original disk drive.

Adds a self-contained SAM2695 General MIDI sound module to an Atari ST-family computer's MIDI output.

The product page exposed a login-or-register-to-buy path on 2026-07-27. The box contains the cased module with an attached short MIDI cable, but the 5 V Micro-USB supply and speakers or headphones are separate. The seller identifies Atari ST use but does not prescribe player software; choose an Atari application that sends compatible MIDI data through MIDI OUT.

Adds an SIO-connected General MIDI file synthesizer with external stereo output and Atari audio mixing.

The product exposed a login-or-register-to-buy path on 2026-07-27. It is a MIDI-file synthesizer, not the MyTek MIDI input/output interface already in the catalog. The public page and human review provide no written player-software, file-workflow, or model-specific SIO-audio instructions. Treat the external stereo output as the documented playback path and confirm software availability before purchase.

Adds three-channel YM2149 or AY-3-8910 sound and stereo line output to an RC2014.

The current Z80 Kits version is sold without a YM or AY sound chip because those parts are no longer manufactured. The builder must obtain a suitable chip. An optional ZXTT module supplies a 1.7734 MHz clock.
