# V0 Errors

## E0001

The machine identification routines from http://www.1000bit.it/support/manuali/apple/technotes/misc/tn.misc.02.html failed to identify the model.

## E0002

The current version of the audit program doesn't support the identified machine.

## E0003

We tried to put the language card into read bank 1, write bank 1, but failed to write.

## E0004

We tried to put the language card into read RAM, write RAM, but failed to write.

## E0005

We tried to put the language card into read bank 2, write bank 2, but failed to write.

## E0006

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.
