E5/6 is H8/539.
I have been thinking about the following....
There are no direct emulators of H8/539 (AFAIK)
H8/539 can be read/written as a HN28F101
HN28F101 EMU does exist.
Put 112pin probe in place of H8/539 and run cable to a daughterboard.
On the daughterboard run the PROM functions to the HN28F101 EMU whilst retaining all other operations to the H8/539 on the daughterboard.
There may be issues making this impossible that I haven't come across yet, but on the face of it seems viable.
