Akai S1000 / S1100 samplers

Hi!

Thanks for the info, very interesting! I have a problem with my camera for now, but yes I am sure you are right about these being 2MB boards. I can tell you that the boards have Intel P21010-08 memory chips - 16 of them. These, google says, are 1Mbit DRAM chips. So, 16Mbit = 2MB = 1Mword. But hey, 8MB in total is OK!

These samplers are so well built, it's no wonder they last forever.

Thanks!

Matt
