Well, thanks to everyone who replied to me about where to shove and where to
get TOS 2.06 I have gotten it to work in my 1040ST without a TEC.  The solution
requires 10 wires from the GLUE chip, 3 TTL devices (<$1) and 5 pins of each
ROM lifted.  The circuit I used is shown below:

TOS 2.06 Address Decoder and DTACK Generator:

  Note:  Numbers in parenthesis on the left are (GLUE pin,68000 pin).
         Parts needed are:

                1 74F138
                1 74F08
                1 74F06

         Different families (LS, ALS, AS) may be substituted for the above
         parts.  The buffer that drives DTACK_ must be open collector or if
         a 7406 part can't be found a tri-state buffer can be used as long
         as it is used like the example below:

                          74LS244
                        +-------------+
                        |        oe(1)|o-------- to pin 7 of 74F138
       DTACK_<----------|y0(18)  i0(2)|---+
                        |             |   |
                        +-------------+   |
                                          |
                                       GROUND


I have been working on a document that explains in detail how I installed
TOS 2.06 (the mechanics is the main deal).  When I finish it, I would like
to place it in the archive but I don't know how.  Could some one please tell 
me how to submit a text file.  Also, if anyone would like a copy of the 
current document just send me email and I'll send you what I have.
