Probably. This can be quantified under an emulator. How much RAM one really needs? Two megs? Four? Knowing this number would put a constraint on the board design. If four megs are sufficient then either ASRAM or ZBT can do and one can still get away w/o a cache. More than four would require DRAM and then a cache is necessary. 

Choosing the board would be better founded if we knew how much RAM is needed to run Linz V4 and ETH System-3. Then at least we could say "this board can run this system, but it cannot run the other one". At this point we are only guessing. The answer can be found with an emulator where you can declare the amount of RAM.
