I will have a look at wxwidgets.

I don't get your reasoning. Someone writing an
emulator in no way
precludes you or someone else from building hardware. In fact, it is a
good stepping stone towards building real hardware. Even when building
new hardware, building a software model first is often useful.
One of the reasons for making this emulator ( the main one in fact ) is that I need a
testbed for changing the drive in my real Lilith from the troublesome Honeywell Bull
cartridge drive, with a propriatary interface, to a WD1001 / MFM drive combo . Might also
go for an IDE disk.
It will involve adapting the microcode, the Medos code and interfacing to the Lilith IO
circuitry, and I would much rather test on a piece of software than risk my irreplacable
real hardware in the development process.
In a later stage I expect the emulator to use the real MFM ( or IDE ) substitute drive.
Only when this works will I adapt the real thing.

Sure. Are you willing to invest in new PCB`s ? I will provide schematics in
Eagle format.

After the Lilith the ETH made the Ceres workstation series. And guess what, no bitslices,
but a standard microprocessor (NS32032, later NS32532 )
A separate Lilith successor seems to have been the Eve series, of which I know nothing (
Richard, pictures !)
