In step C the ROM dump procedure from the Emu71/Win manual uses TITANCHK to verify the ROM dump.

If you expect this to pass the checksums must be correct.

A. finding an ultra rare HHP 96k RAM module,
B. modifying it,
you can just use an emulator with a 64K RAM port.

If the 71 has version 1BBBB firmware, a 32k port must be configured before the 64k port. This bug is documented elsewhere on the Forum and in a few documents.
