Now let's look at another early microcomputer Commodore systems
Actually there is another earlier Commodore system which I have used but I do not have any graphic on it nor do I remember much about it. It is the Commodore PET. PET stands for Personal Electronic Transactor.
This system here is the CBM or the Commodore Business Machine.
Specifications of the Apple ][ was as follows:
CPU - initially 6502 microprocessor, but CBM uses 6504 running at 1 MHz or 2 MHz.
RAM Memory of 16K or 32K (a later model).
VDU - usually monochrome, 40 characters per line
Graphics, poorer than Apple ][, this system was not meant for graphical display
Input-Output - initially cassette, later 5.25" diskette.
Diskette capacity - 340 Kb per 5.25" diskette
Note that this is a later generation than the Apple ][ I mentioned earlier.
