IIci vs IIvx
32k Cache module is Apple's OEM; 64k is DayStar FastCache IIci; 128k is Micron XCEED IIci-128; DayStar 50 is p33 PowerCache; MicroMac DiiMO 50 is 1996 030 Accelerator. SD Card is Kingston 16GB Canvas Select.
Micron 128k module would disable itself when either DayStar's Power Central or PowerDemo is launched. I have a distant memory of Power Central once displaying '128KB Direct Map Cache' but it now displays "No Card Installed." Every other cache size is detected correctly in Power Central.
