Dunno about the IIcx, never had one, but it had Dirty ROMS, so it probably had a SIMM Slot for the upgrade that Apple's buying Mode32 from Connectix prevented. The SE/30 was based on the IIcx and released in the same product cycle, IIRC. The magazines/reviews touted it as a IIcx in an SE case. The /30's all NuBus architecture in any case.
There's no room in in the compact form factor for a NuBus implementation, so Apple went PDS as in the SE precedent.
The later released IIsi was based upon the SE/30 and the IIci, with which it was released, if memory serves. Could be off on that, check all the intro dates over on LEM for confirmation/refutation.
The Mac IIsi was saddled with limited expansion options, slottage and memory this time, as the LEMacII. It was neither fish nor fowl, however fouled up Apple designed it. [
