Question about IIcx RAM Installation
Posted by: smrieck511 on 2026-06-23 12:25:37
I have a IIcx with 4 x 1mb SIMMs in Bank A

Can I add 4 x 4mb SIMMS in Bank B for a total of 20mb (Mode32 installed) ?

I read somewhere about the larger memory needing to be in Bank A but maybe that was just the original Mac II ?

Thanks.

Thanks! Exactly what I was looking for.

So it needs to go 4x4mb in Bank A and 4x1mb in Bank B.
