Before John let me on to the Weller programming software, I found WinHex to
split the files. While not intuitive, it did work and I was able to program
the split ROMs with my other programmer.

Well, I had some minor success with this. I modified the 8086 monitor
slightly to use different console I/O bits in routines CO and CSTS. I get
the monitor banner so the output is fine. The monitor doesn¹t accept any
character input (it echos with ³?² and rings the bell).

The monitor also complains that it can¹t find the 8259 PIC. When I did the
testing during the build, it passed so I don¹t know what¹s up there.

Since the EPROM section is working at least, I may try to program the
original SCP monitor program and see if that works.
