Sweet 16

Once upon a time - pre-IBM PC,  Steve Jobs(?) at apple invented sweet16 for
the apple II.  What is was an emulation of a 16 bit machine using the 8 bit
6502.  Not a true emulation - it was more of an extensions into a combined
software hardware 16 bit machine.

It was quick and it allowed all other software to be written as if the 6502
was a 16 bit machine with index arithmetic etc.

For an ECU project, I am getting heavy into the 68HC11 used on some GM ECU's
and am contemplating using something like this.  I did a rehost of the 6502
sweet sixteen early in the 80's but silly me never kept the paper work and I
draw a complete blank trying to either remember it or remember what I did.

If anyone has the original ( apple bragged heavily about it early 80's ) or
any references to it, could you please e-mail.  Off list is fine.  Thanks.
