When did Commodore 128 release?
January 1985
The Commodore 128, also known as the C128, C-128, C= 128, is the last 8-bit home computer that was commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the bestselling Commodore 64.
What kind of CPU does a Commodore 128 have?
Commodore 128 (D) Personal Computer is great and versatile Dual CPU 8 bit system with Dual Head Graphic chips. Dual CPUs are 8502 for C64/128 (6510 opcode compatible but 2x faster) and Z80 for CPM.
What are the operating modes of a Commodore C128?
The C128 has three operating modes. C128 Mode ( native mode) runs at 1 or 2 MHz with the 8502 CPU and has both 40- and 80-column text modes available. CP/M Mode uses both the Z80 and the 8502 and is able to function in both 40- or 80-column text mode.
What kind of microprocessor was in Commodore C64?
Instead of the single 6510 microprocessor of the C64, the C128 incorporates a two-CPU design. The primary CPU, the 8502, is a slightly improved version of the 6510, capable of being clocked at 2 MHz. The second CPU is a Zilog Z80 which is used to run CP/M software, as well as to initiate operating-mode selection at boot time.
Can a C128 be used as a multiprocessing system?
The two processors cannot run concurrently, thus the C128 is not a multiprocessing system.
