C 128 D-CR - 01 |
The 128D is the direct successor of the Commodore 128 : it has exactly the same characteristics as the 128 except its external case which contains the Commodore 1571 floppy disk unit. Actually there are two distincs Commodore 128Ds : The 128D and the 128D-CR (for Cost Reduced). Differences between the 128D and the 128DCR are : - The 128D was never sold in the U.S. because of all the radio frequency interference it gives off. - the 128D-CR has a metal case rather than plastic. - the 128D-CR does not have a cooling fan, although there is a place to mount one. - the 128D-CR case does not have storage clips for the keyboard. - the 128D-CR comes with 64k of video RAM (for the RGB video chip) rather than 16k for the C128. - the 128D-CR's printed circuit board is different, and includes the drive electronics. So there are 3 CPUs on the board. - the 128D-CR comes with bugfixed (1986) ROMs in two 32k x 8 chips instead of four 16k x 8 ones. - The internal drive's ROM is different from the original 1571 ROM in two ways: it is bugfixed, and it has changes for the new support chips. The bugfixes are bigger than the changes for the new hardware. - 128D-CR CPU RAM is in four 64k x 4 chips rather than sixteen 64k x 1 ones. - the 128D-CR does not have a carrying handle.
