I've been thinking about this for a few years now, but have not gotten together: 1) all the parts needed 2) a spare 200 that works well to test with, but can be sacrificed 3) the nerve to butcher a working lcd panel
However, I thought that this solution: http://www.backlight4you.com/media/products/0418582001187192777.pdf which was crafted for the HP 100LX Palmtop would be a better fit since it is close to the implementation you would need to follow and has all the elements worked out, including modification to the LCD, adding the inverter circuitry, etc. It should require only minor modifications. That said, I hope we see someone put together a backlit 200 someday. btw, I put together a working backlit version of my Tandy 600 back in the day, using an EL panel, which made it much more readable, but I was unable to get an inverter circuit to work and ended up needing two power supplies to run it. (It was never really useable as a portable anyway, but it was really un-portable after that). > On 02/01/2023 6:45 PM Daniel L <[email protected]> wrote: > > > On 2/1/23 16:37, Daryl Tester wrote: > > On 2/2/23 10:55, John R.
