I will have a look at wxwidgets.

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 !)
