I'd have to agree, especially with a DSP or SCSI II Daughtercard installed, or BOTH on a pair of Rockets under RocketShare.
ISTR running mine as an accelerator under RocketWare on 6.0.8 until the Tuneup became available for 7.0.1 and I finally made the jump to System 7.
Just to clarify, the Rocket will run anything that runs under System 7 up to a max of 7.1 Pro, after which Apple broke Radius' license to run copies of the Mac ROMs by borking the AppleShare over NuBus which was the Rocket, and RocketShare's forte.
I've always been curious about the TokaMac(?) TransPuter Based Accelerator, but ISTR something about it only running in the IIfx expansion slot, dunno, no time for research on lunch hour. :
