Ok, now, I actually have about a days experience with this, but I've 
written a ROM dumper into my (upcoming) linker program for the PC.  
ROM86 sends _NO_ special commands, it just sends the data.  So, if you 
just wait until input occurs from the link port and save everything that 
gets sent until you get a timeout (no more data sent) then you'll get 
the entire ROM.  I did this, ran it on my emulator, and it didn't fail 
the self test saying, "Invalid ROM" or anything, so I'm sure the lower 
half of every page of the ROM is correct. (Yes, only the lower half... 
self test only checks the lower half of each rom page)
