These are the most interesting resources in IIe Startup.

These might be Macintosh-side drivers for each of the “cards.”

These appear to be the slot-mapped firmware, but a curiosity is that two of them, the memory card and the workstation card, are larger than the allocated slot space. These are not obfuscated.

ATLK_Card: A quick look shows that this modifies the memory config to switch in one of the PFI banks and then jumps to it.

These have simple XOR obfuscation with the key “DoubleX”.

At least A2EMonitorROM has 6 extra bytes at the beginning, an apparent header that tells the IIe application where to put the firmware
