5 Pecom driver by Miodrag Milanovic
6
7 2008-11-08 Preliminary driver.
8
9 - All commands to be in UPPERCASE.
10 - Change background colour: SCR n
11 - Enter monitor: PROB (B to exit)
12 - If Capslock is engaged, then Shift doesn't work.
13 - Control hangs the machine while it is pressed. It doesn't work in the
14 expected way.
15 - Don't touch the Shift key while loading a tape because it will corrupt
16 the data.
17 - The screen will flash in a crazy epileptic fashion while loading a tape.
18 Beware!
19
20 TODO:
21 - Cassette: can load its own recordings, but not those from software list
22 (software-list tapes are slower & wobbly)
23 - Both machines currently have 32k ram.
24 - Autorepeat seems a bit fast

68 Being keys distributed on four lines, it makes a bit difficult to accurately remap them
69 on modern keyboards. Hence, we move by default Up/Down/Left/Right to Cursor Keys and
70 use Left/Right Ctrl/Alt keys for the remaining keys. Due to the unnatural emulated keyboard
71 mappings, this is another situation where natural keyboard comes very handy! */
