C 128

C 128 D - 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.

At this time I started to buy stuff at ebay (and other auction sites)

The first thing I bought was my Commodore 128 wit a C2N datasette

I bought it (and working) from a guy in Zelzate (price tag: 1000Bfr)

He also sold me a 128D (price tag: 1500 Bfr), 
diskettes (1500 Bfr, paid too much for this), 
an Atari 600XL (500Bfr), Atari VCS2600 + 19 games (500Bfr), 
Commodore VIC 20 (500Bfr), I also got two other datasettes, 
a lot of “damaged” hardware (C64, C64C, C128) and some software.
