I have a magazine article somewhere that describes all the necessary parts, and how to connect it all a track and sector LCD displays with for the 1541 but I have no idea where this article is right now. I've seen pics of a track LCD display with density indicator by UU/Super Copy but it doesn't have sector display or half-track indicator it's not at all practical for copying software, it's just a "cool" mod, but I'd like to put it all together in a drive, have 2 digit LCD for track, 2 digit LCD for sector, 4 small LEDs for density and 1 other small LED for half-track indicator no, I'm not trying to rebuild "The Shadow" (MegaSoft Vaporware) just the display and indicator portions. several things could be added to this, such as a drive reset button, write-protect switch (very simple), device number switch (8/9) also easy put it all together and you could have a little kit for a 1541 to make the drive look very cool so if anyone has any of this info, it'd be appreciated. I'll try to dig up the old article I have, but at the moment I have no clue where it might be. Dan.
