Specification

Commodore 128D (original, not 128DCR)

Condition

The drive seems to have problems reading the highest tracks (33,34,35).

Other than that it is working fine.

I've completely dis/reassembled it, cleaning every part.

Case shows signs of extensive use and colored yellow.

Monitor

The original 1901 monitor was broken long time ago and I trowed it away.

Ever since I've used a green PAL monitor with a special handmade cabling to get both 40 and 80 colomns screen. The 80 coloumns RGBI port has a monochrome pin (7) for this purpose.

Ofcourse for colour 40 coloms I can connect a TV.

But the 80 coloms colors remained lost. Until now, I learned that the 128 RGBI is actually CGA compatible! I do have an EGA monitor. Connecting this to the 128 works except that all low-intensity colors are garbled (white stripes). Using the RGBI cable from the 1901 monitor which doesn't have pin 7 connected solves this problem.
