Complete three-chip EPROM set for the original Alesis HR-16: operating system v1.09 plus both factory sound ROMs (U15 and U16).
Each set is freshly burned from verified factory ROM images and labeled by socket, so you know exactly where each chip goes.
What's Included:
- 1x OS v1.09 firmware EPROM (27C256)
- 2x factory sound ROM EPROMs, U15 and U16 (27C4001)
- No soldering required, chip swap only
Compatible with: Alesis HR-16
If your HR-16 is acting up (won't boot, garbled display, missing or corrupted sounds), a fresh set of chips is often the fix.
