/***************************************************************************
Tesla PMI-80
12/05/2009 Skeleton driver.
20/06/2011 Made mostly working [Robbbert]
ToDo:
- cassette
- keyboard to be finished
- artwork
Notes:
- Keyboard consists of 16 black hex keys, and 9 blue function keys
- The hex keys are 0 through 9, A through F on our keyboard
- The function keys are mostly not worked out although I've guessed a few
- The function key labels are RE, I, EX, R, BR, M, L, S, =
- The letter M shows as an inverted U in the display
- Turn it on, it says ''PMI -80''
- Press any key, it shows a ? at the left
- Press the function key corresponding to what you want to do
- Press the numbers to select an address or whatever
- For example, press M then enter an address, press =, enter data,
press = to increment to next address or to scan through them.
- As for the rest, no idea
- In the layout, there is a 10th digit. It is disabled but if you
enable it (by renaming 'digitx' to 'digit9'), it will display
things. Perhaps it connected to discrete LEDs or output lines.
