ABC CAD Mouse/Hi-res video card
|
||||
|
||||
The ABC CAD was an innovative electronics CAD accessory invented by
|
||||
Marek Gorczyca, Betronex Elektronik AB 1983 to overcome the limitations
|
||||
in the ABC80 microcomputer graphics which was very popular in Sweden at the time.
|
||||
|
||||
The mouse feature is in the form of a small box with a handle sticking out at the front.
|
||||
The handle can be manipulated in one direction by turning it around its internal pivot
|
||||
point left and right. The other dimension in handled by pulling and pushing the handle.
|
||||
One button is available on the top of the handle.
|
||||
|
||||
The mouse is connected via the ABC bus, but also passes through the
|
||||
ABC80<->Monitor power/AV cable
|
||||
|
||||
The mouse was sold with the PCB CAD program "CAD-ABC"
