2
3    BBN BitGraph -- monochrome, raster graphics (768x1024), serial terminal.
4
5    Apparently had at least four hardware revisions, A-D, but which ROM
6    revisions support which hardware is unclear.  A Versabus slot, and
7    various hardware and software options are mentioned in the docs.  Best
8    guesses follow.
9
10    Onboard hardware (common to all revisions) is
11    - 32K ROM
12    - 128K RAM (includes frame buffer)
13    - 3 serial ports, each driven by 6850 ACIA
14    - some kind of baud rate generator, possibly COM8016
15    - sync serial port, driven by 6854 but apparently never supported by ROM
16    - 682x PIA
17    - AY-3-891x PSG
18    - ER2055 EAROM
19    - DEC VT100 keyboard interface
20
21    Rev A has additional 4th serial port for mouse (not supported by ROM 1.25).
22    Rev A has 40 hz realtime clock, the rest use 1040 hz.
23    Rev A-C use AY-3-8912 (with one external PIO port, to connect the EAROM).
24    Rev D uses AY-3-8913 (no external ports; EAROM is wired to TBD).
25    Rev B-D have onboard 8035 to talk to parallel printer and mouse.
26    Rev B-D have more memory (at least up to 512K).
27
28    ROM 1.25 doesn't support mouse, setup mode, pixel data upload and autowrap.
29
30    Missing/incorrect emulation:
31        Bidirectional keyboard interface (to drive LEDs and speaker).
32        8035.
33        EAROM.
34        1.25 only -- clksync() is dummied out -- causes watchdog resets.
35        Selectable memory size.
36        Video enable/reverse video switch.
