A few more additions – very likely the last.
I've installed a PCI/ISA-bracket CF-to-IDE adapter, and am now using a 2GB CompactFlash card as the primary hard-drive.
I've installed an external S/PDIF bracket, thereby gaining use of the AWE32's digital OPL3 and EMU8000 output. This necessitated the use of an external DAC, which was found cheaply in the form of a Klipsch ProMedia DD-5.1 pre-amplifier. When comparing the S/PDIF output to that of the AWE32's analog output, it's amazing how muddy the latter is.
With the LAPC-I, IMFC, and Game Blaster connected to the DD-5.1’s switched inputs, I am also no longer using the Midiman Multimixer. PCM playback (as well as the WaveBlaster header output, unfortunately) still exits the AWE32's line-out, and is routed into the Bose MediaMate speakers that flank the monitor.
There's little (if anything) left to do. I may remove the Matrox card at some point, and just use the on-board Cirrus Logic chipset.
That's all, folks!
