The IIsi has a wider case with ribbing molded on the bottom that provides vertical height for the
Basement Hack that's unavailable in the Compact Mac cases.
@ Charlieman: the
Sub-Basement Hack approach that you've suggested is what I'm using in the
MacintoshClassicIIIColorTVp™ Hack, but it would be cheating for this exercise. I'm imposing a "Within the Case" limitation to my
SuperIIsi™ Hack to keep comparisons of it with the SE/30 gamba hacks on an even footing, so the reverse would need to be true as well. I'm also limiting the
SuperIIsi™ to period correct technology/expansion options.
When I benchmark the final
SuperIIsi™ hack, I'll do so with and without the SCSI II DaughterCard and the external Fast SCSI II RAID in the StudioArray implementation to preserve the "within the case" comparison limitation. A third possible configuration would be using the StudioArray's Short Cable in a loop-back config for an
internal Fast/SCSI II implementation. This I'll do in simulation because I don't want to muck up the IIsi plastics any more than I have to. The
unobtanium status of the SCSI II DaughterCard for the Rocket precludes any possibility of a present day hack of
internal cabling to its external connector's soldertail pins. However, when the gamba hacks were done to the SE/30 during its practical use lifetime, hacking the Rocket's DaughterCard in this manner to avoid "outside the case" cheating would have been duck soup! [}

IDK, but I'm almost certain there's too little room in the mezzanine area of the SE and SE/30 at the rear of the case to leave the Stock PDS Connector on the MoBo intact for this hack.
1)
Ceiling Height availability at the rear end of the mezzanine appears to be so tight that the Expansion Card PCBs will barely clear the metal ceiling at the rear end of the Chassis.
2) The
Back-Side Connector Modification is required to clear the MoBo Components, even in the unlikely event that the MoBo PDS Connector can remain intact.
3) There is too little height available for the
"Back-Side" Hacked PassThru Connectors, so an opening (
SkyLight Hack) in the chassis will almost certainly need to be cut for them in any case.
4) If I had an SE/30 and wanted to try to compete with the
SuperIIsi™/Rocket Hack, I think I'd probably resort to fabricating something similar to the clear plexi chassis of the
MacintoshClassicIIIColorTVp™
This would open up a lot of expansion options for the Compacts. The only reason there's any vestige of the original Classic Chassis is that I want to demonstrate that the single Slot inverted Sonnetized MoBo Hack is practical within the confines of the Compact Mac case and chassis.
5) The diagram in the previous post shows a Soldertail Socket mod to a PDS expansion card that would then be soldered to the SE/30 MoBo slightly lower than the top of the removed PDS Connector. I should have indicated this in the diagram, so I'll play with it in illustrator and post new diagrams.
6) Machine pins won't work for this hack unless they are available in a wire wrap configuration. This is something I'll be checking out as a more readily available (and more vertically flexible!) part than wire wrap NuBus/PDS EuroDIN Connectors. The Mezzanine Transition Card needs to be a Male/Female Config, which is why the Wire Wrap EuroDIN Connector is shown.

As far as the hacking of
LC 'zaBoxen (absolute worst case scenario in terms of cubic availability . . . the most challenging . . . therefore the most interesting "case" to me! :approve: ) goes, I don't recall seeing any LC PDS Cards that have a PassThru other than the PowerCache Adapters, but you've given me the notion to do a
Betwixt-MoBo-n-NIC hack for my LC! I've got a VidCard for it on order with macmetex, we'll see about such possibilities when I figure out the rest of the Radius stuff for the order. It will more likely wind up a
Betwixt-MoBo-n-VidCard NIC Hack on second thought. Dunno, I'll have to source a NIC as well before exploring such things, PseudoSlot Addressing issues allowing, of course.
All that has to wait until the toy budget begins to replenish after the shipping budget fills-n-empties. :-/
