You're watching an EPROM with OS 2.5U for the Roland Alpha Juno 2 synthesizer and also the HS-80, the speakers version. You should only use it if your synthesizer has a U label in the old EPROM. For other versions, please contact.

I only sell EPROMs for the synthesizers that I own - everything is tested properly. The EPROMs' window is sealed with UV proof aluminium label.

I have a huge collection of synthesizers, I am always available to help in stuff related to the ones I own. Check my other items - decent prices for top products sent immediately, well packed and tracked mail.

These are NEW products, not new old stock. I have sliding pots for most vintage gear, including most Korg, Yamaha and Kurzweil. Some rotary for older Moog (Micromoog) and Transcendent 2000. Also some switches and some SSM and Curtis (CEM) chips. I will be selling all these in the next few weeks. Contact if you are looking for something. I repair (and collect) synthesizers since 1992.

I will send worldwide (tracked) for free. I'll ship same day or next, depending on payment hour.
