Reading HP67 ROMs

[Marcovecchio]

This is great, Tony! There is a lot of effort and knowledge in there, many thanks for putting this together.

And also, thanks for ROM0 support, this is a very welcome addition! With this piece of hardware, it will be much easier to pinpoint defective chips on classic or spice calculators. And I think it may work with Woodstock ones with almost no modifications, right?

This ROM dumper might even evolve in the future into a ROM checker / identifier, all that is needed is a small table of CRC pre calculated vales for the known ROMs. Then the ROM would be read, have it's CRC calculated and compared to the table. If found, the ROM is both OK and identified with no margin for error! This feature might be completely implemented as software at PC side.
