TODO:
- implement proper i8214 routing, and add irq latch mechanism;
- implement proper upd3301 / i8257 text support (currently hacked around);
- Add limits for extend work RAM;
- cassette support;
- waitstates;
- support for partial palette updates (pretty off in p8suite analog RGB test if enabled);
- understand why i8214 needs a dis hack setter (depends on attached i8212?);
- clean-ups:
- slotify extended work RAM, make sure that p8suite memtest88 detects it properly;
- better state machine isolation of features between various models.
Vanilla PC-8801 doesn't have analog palette, PC80S31 device as default
(uses external minidisk), other misc banking bits.
- refactor memory banking to use address maps;
(uses external minidisk), only model with working border color, other misc banking bits.
- refactor memory banking to use address maps & views;
- double check dipswitches;
- Slotify PC80S31K, also needed by PC-6601SR, PC-88VA, (vanilla & optional) PC-9801. **partially done**
Also notice that there are common points with SPC-1000 and TF-20 FDDs;

- Kanji LV1/LV2 ROM hookups needs to be moved at slot level.
Needs identification effort about what's internal to machine models and what instead
can be optionally installed;
- implement proper joypad / mouse (PC-8872) DB9 port connector;
- implement proper joypad / mouse (PC-8872) DB9 port connector, consider deriving from vcs_ctrl;
- Pinpoint number of EXPansion slots for each machine (currently hardwired to 1),
guessing from the back panels seems that each model can install between 1 to 3 cards.
Also note: most cards aren't compatible between each other;
