Yep! No worries 'mate, I've got my original Rocket 33/32MB for testing purposes. [

The SCSI II Daughtercard won't be installed until everything is purring along nicely with room for the RAM above the IIsi's LOW PROFILE HDD.
This is akin to the two Apple II CPUs acting as I/O co-pros in your IIfx.
RocketWare eliminates the AppleTalk over NuBus overhead wth the host CPU as well. When the MoBo Proc isn't worth sharing, acceleration under Rocketware is the only way to go, given a single Rocket configuration, this is something I determined back in the day on my IIx.
This hack has to appear dead-stock from front, side & top views! The Rocket/SCSI II Daughtercard will be mounted in the standard IIsi NuBus Adapter. Unless, of course, I can get the DuoDock Gemini Card Hack to work. Then I'll need to finagle a different backplane cover plate to compensate for the shift straight away from the NuBus Adapter's hacked single slot, If all works out according to the vision, the Lower Slot will have a [color-red]RedRadiusPixelRocket™[/color] installed for 1024 x 768 x 24bit of NuBus Block Transfer 19' Display Goodness!
The PDS Slot is being shifted to the basement under the MoBo and the PDS Card(s) will be "stacked" sideways as compared to the SE/30.
The only sticky point will be breaking the IIsi's lamed PseudoSlot limitation of three available addresses.

Correct, under Rocketware the '030 will be relegated to an I/O co-processor that won't even be hindered by the Vampire Video Subsystem's wait states.

The 20MHz system clock on the IIsi makes it 20% faster (+ or - real world imposed limitations) for using any peripherals (Zip Drive, scanner, etc. on MoBo SCSI) than it was on my 16MHz IIx back in the day, or the SE/30 System/PDS clock. The RCPII/IIsi(s) ought to be noticeably zippier on the IIsi than on the SE/30 do to the higher PDS throughput as well.
Nope, that'd be cheating, comparisons to the SE/30 would be meaningless in that scenario, not that they're all that fair to begin with! }

That's the Plan of Battle, the side benefit is to demonstrate a more elegant way to stack the '030 PDS Cards than anything documented on gamba. :approve:
