I am looking for information about a 32-bit Motorola-compatible DMA 
controller. I have been using the 68450 4-channel DMAC in my design, but
the kludges needed to generate 32-bit transfers are quite ugly. Does
anyone have information about the Motorola 68442? It appears to be
a real 32-bit DMA controller, but does it have 4 channels?
Also, does anyone know of any third-party devices which might do the
trick? (i.e. 32-bit, 4 channels). I am looking for a "Motorola-compatible"
part, since this DMAC will live on a VME board (I know Intel has some
good DMACs, but getting an Intel part to work on a VMEbus...)

Thank you in advance...
