Terry
Gulczynski has disassembled the XCON8 ROM (part #444-70) and added
very helpful comments to make it more understandable. Eventually we
will incorporate GIDE boot code into the XCON8 ROM for use with the H8-Z80-64 Rev 2 CPU
card. The XCON8 ROM is the front panel control code for the Heathkit H8
computer. The commenting of this source file is not 100% complete but
it's a good base for those who want to get started early with their own
modifications.
XCON8 Source Code as of 9/22/2009
