Known quirks
- "Wicked Fast" but fiendishly expensive — $9,900 at launch
- Requires special fast-page-mode 64-pin SIMMs — unique to IIfx, hard to find
- Dedicated I/O processors (IOPs) make it incompatible with some drivers
- PRAM battery uses non-standard 7.2V lithium — easy to install wrong battery
- SCSI terminator must be internal — requires special terminator block
