Hallo Per, Regarding the email that didn't get to the CBM-hackers, this appeared to be my error. Last Tuesday I received a notice that my email (from days ago) was blocked because the name was not on the list. That's how I found out that the spamtrap in the name, which I thought I had removed, still existed. Hallo allemaal, As you know some time ago I bought a PDC Clipper. If you forgot what it was: a c64 plus add-on board for extra I/O, 5" plasma screen, thermical printer and a 3" floppydrive, all packed in a bussiness suitcase. The product as so wasn't a success, the firm went bankrupt. But my first C64 was in fact the MB, add-on card and the keyboard of such a PDC I bought in a shop that bought the left-overs of the company. The main problem from beginning on was that the 3" drive that came with the PDC wasn't working well. Then I could lay my hands on two coming out a brooken Amstrad PCW Joyce. First problem: the original drive had a 34-pins edge connector as found on a 5.25" drive, the PCW one had a 26 pins. Although I found a lot of info on the internet, not the needed pinout of this drive :( Last week I could lay my hands on two CPC6128, that have the same internal 3" drive as well. The 6128 should have a 34 pins edge connector but mine didn't, they had a 36 pins Centronics connector. Which meant that these must be the Plus version. But problems again, the numbers of the pins of the connector didn't match the ones mentioned in the docs from various places on the Internet. But all those docs said that the lower row should be ground and the upper row signals. And in my case it was the opposite. I finally found out what is what by comparing the given lay-out with schematics of the FDC-card of a PC and measuring what pin goes to what IC on the MB. As the 3" drive was coupled to this Centronics connector as well, I found out what the layout of the 26 pins connector was. Then I made a 34->26 convertor and tested things. But still things didn't work out for the PDC. On the end I found out that these Amstrad 3" drives had power connectors where +5V and +12V were swapped !!! Having a working 3" drive for my PDC now, the first thing I did was formatting a disk and displaying the directory.
