DEQNA and DELQA (Qbus Ethernet adaptor) DELUA is Ubus and older.

I'd be surprised the CPU is fried.  Stolen for other uses maybe. 

The 68K came in two major forms one was 16 bit bus the other was 8bit bus.
That swap would be likely to hurt the cpu.  The other variants are package,
mask revision levels ( due to bugs in the microcode) and Clock maximum.
