1050 Drive Notcher Modification

1050 DISK DRIVE MODIFICATION
This disk drive modification is for those people who are tired of not being able to right to side B of all there disk with out having to notch the disk. This drive modification will enable you to toggle between normal operating System to a read only or read right system. The read right system ignores the disk notch altogether. The read system will not right to any disk weather it is notch or not. And the normal operating system work like an unmodified drive.
I assume no responsibility for this disk drive modification. However I would make sure my drive was out of warranty before making any kind of modification to it. I would also read the text of the modification before starting. If you have any question about this modification please leave E-mail.

This tool list dose not summaries all tool's or material you may need. It is just a few of the helpful. I left the mounting to the discretion of the owner of the 1050 disk drive. (I put my modification in the aluminum case listed above an located it on the top of my drive)
J11 and CONNECTOR 11 To make these two part's haft to be made. All you need to do is to cut a wire rap socket in half. There you have your two connector made. Too install you drive modification you must disassemble your drive. You do this by first putting a blank disk in your drive. Then turn your drive over and remove the six Philips screws that hold the two parts of the drive enclosure together. You need to lift from the back and forward to separate the two halves of the cover's. At this time you need to mount the two switches somewhere on the top cover. Then look towards the back of the drive and to the left and you will see a row of connectors. Take a felt tip marker and draw a line on one side of the connectors. And know look for J11. Remove connector J11 by using your long nose pliers and pulling on the connector body not the wires. Replace J11 with the j11 of the disk drive modification. And then plug in J11 into connector 11 of the drive modification. You are finished know. Troubles you may encounter The only thing that could be wrong is a connector may be reversed or you may have made a mistake in soldering the switches together. Also the tricolor led can be solder with no regards to polarity
&99
NORMAL OPERATING SYSTEM= no light
READ ONLY = red light
READ RIGHT = green light
The last two can be changed by reversing the leads of the tricolor led.
MATCH ALL LETTER'S TO THE BACK OF THE SWITCH, FOR THEY ARE THE WIRING SCHEMATIC
I hope you get as much use out of this drive modification as I have.
