Exactly, Moose. Duplicating the board as it is would probably also
infringe something, somewhere. :-) So much better to "black box" it like
was done with IBM BIOS chips "way back when". As long as the inputs and
outputs match the function of the original Olympus board, the camera
won't know the difference.
Because of when the boards for the 4T had to have been designed, I
expect what took custom chips then might well be reproduced with
off-the-shelf programmable stuff now. Seriously impractical? Maybe now.
But when the last of the 4T boards are gone... It'll be much less
seriously impractical for anyone that wants to resurrect one.

I think what Scott is proposing is not a duplication of the old circuit,
which is certainly wildly impractical. He is suggesting something more
along the line of seriously impractical. <snip> What I understand Scott
to be
suggesting is programming such a beast to duplicate all the I/O
functions of the 4T curcuit. The whole thing could be much smaller and
would be much cheaper to produce than a replica board.
