* EXL 100
- Exel Basic (exelbas) can be used in a limited way
- Other software mostly ignores inputs, and usually freezes soon after start (cpu problems?)
- Cassette interface has been added, but don't know the commands to use it.
* EXELTEL can get to the inbuilt "cart" but stops with a black screen,
presumably because the I/O processor is not emulated
