1st: The 6100 will run all of these programs if they currently run on any
040 machine. Older programs that conflict with system 7 or the 040 cache
protocols will obviously still conflict with the powermac. Speeds for the
powermac in emulation will vary between a fast 030 (IIci) and an 040

2nd: The powermacs are running under LC68040 emulation rather than MC68040
emulation, meaning that they probably will not run programs that strictly
require floating point math. None of your programs seem to have this
requirement but it's a consideration for future usefulness.

3rd: The LC474 and discontinued Centris 610 have LC040s without floating
point enabled so you'll have the above restriction anyway. The Centris has
been replaced by the 25MHz Quadra 610 which has an active FPU in all but
the base configuration. This computer is in the same price range as the
Centris was although many people are offering deep discounts on the Centris

4th: The built-in ethernet devices on the Centris and Quadra machine will
still require an adapter depending on the flavor of Ethernet your network
uses...about $100 to add to your total cost.

5th: I'd put my money on a Quadra 610 with MC040 considering the current
and foreseeable needs of the aforementioned programs.
