Pictures of my Commodore C128DCR

I bought this unit second-hand, but I don't know who owned it before me, since I bought it through a third person. The internal drive doesn't work perfectly, it sometimes has problems reading the back sides of disks, mostly on MFM disks.

This unit has serial number DA4 199200 and was, like the rest of the stuff, manufactured in West Germany.

I have added JiffyDOS to it, which causes problems with the Swedish nationalization, since it doesn't recognize the ASCII/CC key (it is interpreted as CAPS LOCK) correctly, nor the Swedish keyboard. I have also added switches to change the device number of the internal drive, that's what the two switches that can be seen to the right on the front shot are for, the leftmost switch is the JiffyDOS one.

However, I have since removed the JiffyDOS ROM (for the computer part) since I equipped the machine with a SuperCPU. The SuperCPU adapter has its own JiffyDOS, which, fortunately, is compatible with the Swedish ROM, so I put that back. This does, however, mean that I do not get JiffyDOS when the SuperCPU is disabled.

Another thing that is modified is the power supply, since one the heat sinks broke. I have now connected those leads to the case, leading of the heat there instead.

The cool thing about the DCR version is that it has not just one, nor two, but three CPUs on the motherboard: one 8502 that controls 64 and 128 mode, one Z80B that runs CP/M, and one 6502 that controls the internal disk drive.
