at the end the vectors won. everything is now vector based in games (as an opengl or directx scene .-) more about this in the simple demo sinZ on pouet last year. therefore step back, step into the beginning 80ies with assembler and the vector console vectrex. and of course vecZ is a shootemup the most complicated (timing, a lot of action etc.) thing in those times.

this computers came with an operating system, gui-based and mouse. basic was a prg to use (not anymore line based). there were some new styles of basics coming up like gfa-basic, omikron-basic (atari st). 
and the most games were coded in assembler (68000 was a god processor for assembler). so you had to buy assembler, which was not included.

The difference between Homecomputer and Businessmaschines was clear for the homecomputer users. Homecomputers were cheap, colorful, had sound, modern (GUI) and you could play with them. So they were designed for ‘fun’. And they came all in one - as one consumer product. So it was ‘identity’. Clear that the Amiga was first designed as an Console. On the hardware side the homecomputers didn't use the ugly intels like almost no Arcade-Console-Maschine did. The question here why? Perhaps because the most of the Software had to be coded in Assembler? 
One of the big question was: Is the Macintosh a Homecomputer? One answer it was to expensive for beeing a homecomputer. Perhaps the homecomputers were the cheap versions of the macintoshs.

Keyboard C64

The Theory
Limitations
The technical limitation on the C64 Keyboard hardware is that not more than 2 keys may be pressed at the same time if you want to be 100% sure the result is valid. In some cases, three keys will work fine but whenever 3 keys form a right angle in the keyboard scan matrix, a 4th letter will appear. The combination “ABC” will work fine but the combination “ASD” will form such a triangle and the matrix will also report that the “F” key is pressed. Same goes for “ASF” which would incorrectly read a “D” the same way.
In short, the C64 keyboard is not a piano where you can play choords and stuff.
