Interesting. If you look at the daughtercard on the PDQ-1000 (next to the probably-a-pentium-ish-CPU-fan), it looks pretty much like a PC/104 connector (upside down, of course) and the back panel port config is oh-so familiar. I'm betting a bog-standard embedded X86 system (new enough to have PCI) with a QBus interface running an emulator. As to the PDQ-2000 and -3200, I bet those are just Intel motherboards in a rackmount case. Chris Elmquist pointed out the CCI1016 looks (to me as well) to be a Comtrol RocketPort. The CEI-1000 is pretty clearly one of the myriad of Intel desktop Ethernet adapters. Their DQP-1100, -1300 and -1500 are DRV11 work-alikes made by Logical.
