// TERMINAL EMULATOR
29
//
30
// Emulates an ADM 3A dumb terminal, with a MITS serial I/O board interface.
31
// Two ports are emulated:
32
//
33
// 0: Control
34
// 1: Data
35
//
36
// The MITS serial card has all of its configuration performed by jumpers on the
37
// card, which means there is no programming configuration required. The data
38
// to the terminal is sent out of the data port, while the data from the
39
// keyboard, which is not yet implemented, is read from the same data port.
40
// The parity is ignored on output, and set to 0 on input.
41
//
42
// The control register ignores all writes, and returns $80 if the terminal is
43
// busy, otherwise $00. This is the output ready to send bit. The busy bit
44
// reflects if the state machine is processing an operation. This is a cheat
45
// that only works with our emulated terminal/serial board pair, because
46
// normally there is no way for the local CPU to know that the remote terminal
47
// is busy. This can lead to problems in the real world, and it's why Unix
48
// "termcap" terminal descriptions commonly have waiting periods perscribed
49
// time consuming operations like screen clear. This emulated terminal is
50
// "ideal" in that it accounts for all of this automatically, but it does not
51
// hurt the realisim of the emulation. An application that performs delays based
52
// on real terminal operations won't be incorrect because it performs a delay,
53
// but a stupid application that relies on this "smart" implementation might
54
// fail to run on the real thing.
55
//
56
// The ADM 3A terminal emulation is based on "ADM-3A Operators manual" of 1979,
57
// and "ADM 3A Dumb Terminal Users Reference Manual" of April, 1986, and the
58
// Unix termcap definition of the terminal.
59
//
60
// Several actions of terminals are typically not listed in the documentation,
61
// and the ADM 3A is no different. That's why termcap exists. The following
62
// actions were derived from the termcap definition:
63
//
64
// 1. The screen clear command also homes the cursor.
65
// 2. Giving the terminal a right cursor command while at the right side of the
66
// 3. Screen wraps the cursor around to the right, one line down. If the cursor
67
//    is at the 80th collumn of the 24th line, it will then scroll.
68
// 4. Down cursor (line feed) on the 24th line scrolls the screen.
69
//
70
// Note that rule (3) causes the terminal to be unable to ever write a character
71
// to the collumn 80 character of line 24, which is interesting if you are
72
// writing a full screen editor. The ADM 3A had a switch for this behavior, but
73
// the user could hardly be expected to open the side panel and flip this switch
74
// to be able to edit.
75
//
76
// The following actions are unknown:
77
//
78
// 1. A cursor left command given when the cursor is at the left side of the
79
//    screen has unknown effect. According to termcap, it is not to go to the
80
//    end of the next line up. I have guessed here that it is to simply
81
//    refuse to move.
82
// 2. A cursor up command given when the cursor is at the top of the screen
83
//    has unknown effect. I have guessed here that is is to simply refuse to
84
//    move.
85
//
86
// These are terminal features there are no plans to implement:
87
//
88
// 1. ENQ or answerback mode.
89
// 2. Bell (where would it go?).
90
// 3. Ctrl-N and Ctrl-O keyboard locking and extention port.
91
// 4. Graphics modes. This was added in later ADM 3A terminals, so were unlikely
92
//    to be used in early software, and would take up another table.
93
// 5. Any of the setup modes or features, as operated by the keyboard.
94
//
95
// The ADM 3A terminal will pretty much serve as an upward compatible version
96
// of the ASR-33 teletypes (Western Union Surplus) that were also commonly used
97
// in the time of the Altair. The ADM 3A was a common replacement for such
98
// units.
99
//
100
// Bugs/problems/issues:
101
//
102
// 1. The emulation was occasionally observed to hang. The CPU was still running
103
// and polling the keyboard, but no reply is received when keys are hit. The rdy
104
// signal is not coming from the low level keyboard logic.
105
// 2. Cursor left at left hand side does not refuse to move (see above).
106
// 3. moving to the 80th collum on line 24 and typing a character does not cause
107
// the screen to scroll.
108
// 4. On sign-on, the first two characters are missing the top row. I suspect
109
// this is due to the start of frame character preloading that is done.
110
// 5. \ESCGc or set attributes does not work from the keyboard unless you hit
111
// caps lock or hold the shift key down before and after the escape. It should
112
// work anytime the upper case G is hit.
113
// 6. Need to add reduce modes.

740
// on the PC. Instead, 640x480 was a standard VGA mode for graphics. I like it
741
// because it unifies graphics and alpha modes, and has even divisions to
742
// character cells. Its a bit difficult to fit characters into a 8x20 cell,
743
// but the modes used for alpha, like 640x400 or 640x300 are not 4:3 aspect
744
// ratios, and really work by stretching the pixels vertically. We just do
