Commodore 128 [1]

Commodore 128, (C128)
an 8-bit home computer released by Commodore Business Machines in 1985 as significantly expanded successor of the Commodore 64. It was a two processor machine with 128 KiB of RAM, using a 6502 aka C64 compatible 8502 processor, and a Zilog Z80 CPU to run CP/M beside Commodore BASIC. An unusual feature of the C128 among CP/M systems is that some of the low-level BIOS routines are executed by the 8502 instead of the Z80. The latter transfers control to the 8502 after placing the pertinent parameter values in designated memory locations. The Z80 then turns itself off, being awakened by the 8502 at completion of the BIOS routine, with status value(s) available in RAM for inspection [2].
