/***************************************************************************
Eltec Eurocom II V7 single-board computer. Used in PPG Waveterm A.
to do:
- Eurocom board: timer, interrupts
- Waveterm: PTM, ADC, DAC, 'end' button
- autoboot Waveterm software without -debug being necessary
- support more disk image formats (.dsk, flexemu .flx)
