LT1 Data Tables

[Daa Wagon]

>>how the tables are -referenced

the anht hac is completely commented, and has some
subroutines 
which are identical to the LT1, like the lookup ones,
a couple 
filter subs, etc.

the anht hac is the $8d one on this page
http://www.geocities.com/MotorCity/Shop/9938/tuning/do_tune.html
    

In the LT1 t side they are called as subs, the e side
has them mostly right
in-line.

for 3d tables, the real base addr of the table is 3
bytes before the start of 
the data.  anht explains it.

   so look for 2087 instead of 208a.

* 2. Q min value, (Col's)
* 3. RNUM, number of Q Vals, (col's)
* in each R table
* 4. Thr 1st R table, R num entries in length
*
* 4 + RNUM secont R table
* 4 + (N-1) Nth R table
*
* CALL WITH:
* A Reg = R input, (Row arg)
* B Reg = Q input, (Coll arg)
* X Reg = Table start address
*
* RETURNS WITH:
* A Reg = F(Q,R)
