Roms for Kurzweil Synthizers / Keyboards (as archived from Alzerom.com)
As with the Arcade and Pinball roms, there are way too many roms to list here, and I am not an expert when it comes to Kurzweil. This is a collection of popularly listed sets, and can add more by request.
If you don’t see what you need, use the “contact us” link at the top right of the page where you can email me and I’d be glad to check my archives!
Kurzweil K1000 HX/SX/AX to PRO-2 Rom Upgrade Set
The HX, SX, and AX versions were bundles of 3 eproms each:
HX U51 U55 U59
HXA U53 U57 U61
SX U50 U54 U58
SXA U52 U56 U60
AX = SX + HX
The upgrade to PRO-2 requires ALL 12 eprom chips, AND the 4 new OS chips. The bundles you need to fill the 12 sound roms, will depend on which configuration you already have installed currently

The PX version comes with 6 Sound eproms [U50,U51,U54,U55,U58,U59]. To upgrade to PRO-1, you need the PXA upgrade [U52,U56,U60], the PXB upgrade [U53,U57,U61], as well as the 4 OS chips [U21, U22, U32, U33].
