skeleton: Renamed Vector 4 to Vector 3. (#10697)
It appears Vector Graphic Monitor 4 was confused with Vector 4. Fixed some of the easier Vector 4-isms, but it will need more thorough work.

2009-12-08 Skeleton driver for "Vector 4".
|
||||
2022-12-03 Renamed driver to "Vector 3"
|
||||
|
||||
According to the net the Vector 4 came out in 1982, but BIOS 0 has a date
|
||||
of 1979, so perhaps it's for some other model.
|
||||
This driver was based on the Vector 4 User Guide but accidentally with the
|
||||
Vector 3 or other ROMs, because of confusing naming. To get the ROMs to work
|
||||
required Vector 3 behavior.
|
||||
|
||||
Although each bios set identifies as Vector Graphic, none of them align
|
||||
to what the user manual says.
|
||||
The Vector 3 and Vector MZ had similar internal hardware. Both are based on the
|
||||
ZCB, Flashwriter II, and Micropolis floppy controller.
|
||||
|
||||
The manual gives a list of ports (listed in the i/o address map). There's
|
||||
no schematic.
|
||||
The 7100-0245-00-00 Extended Systems Monitor 4.3 Users Manual seems to
|
||||
correspond with BIOS 1.
|
||||
|
||||
BIOS 0 only talks to UARTs at 2-7 and nothing else. It uses a terminal
|
||||
for all communications.

|
||||
They also write a video screen at F000-F7FF, but there's no writes
|
||||
to any video controller. Also, the chargen roms (2x 2716) are missing.
|
||||
|
||||
The system contains a 8088-2 cpu for limited IBM compatibility, but
|

the manual has no mention of it besides its existence.
