Info: FM-YAM

FM-YAM is a Commodore SFX Sound Expander compatible cartridge for the C64 that adds 9 channels of FM sound. It is comparable to adding an AdLib sound card to your C64. It comes in a 3D-printed red case (other colors are available).

Several online demos highlight its SID + FM capabilities, making this a versatile gadget for those interested in C64 audio https://www.youtube.com/watch?v=EbeoLqEpb9s

The FM-YAM is currently available to order or pre-order from Xentax http://c64.xentax.com/index.php/fm-yam.

The approximate price is 38 EURO (excluding shipment of 6.20 EURO). However, Xentax make FM-YAMs on demand, and batches / prices vary with demand. The first batch of 120 units was released in March 2018 and quickly sold out. As of 2022 almost 360 units had been sold from a total of four batches.

Review[edit | edit source]

A full review of the FM-YAM is available in the ZZAP-64 Annual 2019.

Software[edit | edit source]

Native C64 FM editing software is possible with the original Sound Expander software.

However, a D00 file player is provided, meaning composers can use Edlib (a DOS tool that can be run in DOSBOX), an Adlib-based tracker that saves music as D00 files. These D00 files you can then play using the C64 player code. Additional software is planned.
