I got an 1050 disk drive in the last days and after open it, I´m surprised! Never have seen such a model before, and I have opened more then 50 different 1050´s in the last years.
So... anybody knows this model? My first thougth was, that this must be a pilot production model from the early days of existing 1050´s. After showing the pictures in the german ABBUC forum, somebody assumed that this model might be a clone, produced not from Atari.
The case looks like a normal 1050 case, but the brown front bezel doesn´t fit on any other 1050 case and vice versa. The mechanical drive is totally different from the normal Tandon & world series models. The PCB has some manual corrections and scratched traces, but looks nearly equal to any other series 1050 PCB. The color of the solder mask is other than normal. The metal shielding of the major ICs is not quite silver as usual.
Any ideas welcome.
