 ## E0007
 
 This is a data-driven test of Language Card operation. We initialize $D17B in RAM bank 1 to $11, $D17B in RAM bank 2 to $22, and $FE1F in RAM to $33. Then, we perform a testdata-driven sequence of LDA and STA to the $C08X range. Finally we (try to) increment $D17B and $FE1F. Then we test (a) the current live value in $D17B, (b) the current live value in $FE1F, (c) the RAM bank 1 value of $D17B, (d) the RAM bank 2 value of $D17B, and (e) the RAM value of $FE1F, to see whether they match expected values. $D17B is usually $53 in ROM, and $FE1F is usally $60. For more information on the operation of the language card soft-switches, see Understanding the Apple IIe, by James Fielding Sather, Pg 5-24.
