Where can I get a sufficiently detailed description of the Hercules interface to do the same? I bought a Leading Edge model 'D' ,which uses a herc-cloned mono interface but comes with no technical info about it. Do you read and write to the hardware directly or does the Phoenix BIOS support a herc interface? The regular IBM BIOS does not. Thank you in advance. --Peter Nelson
