Hi everyone...back from the lurking silence... I've launched an 8MB RAM expansion board for the Yamaha SY99. It's designed from scratch and installs right under the bottom cover. https://www.wohmart.com/sy99-mmb.html I'm also selling the upgrade EPROMs and CPUs necessary if you've got an older OS version on your SY99 than 1.57. Combined with the WaveBlade, this is a fantastic option to max out your SY99 and make some killer music. This is my first for-sale electronics project in nearly 20 years, so I'm pretty proud. If anyone has any questions, I'd be happy to answer them. Cheers, Joan @ WohMart.com
