Excellent Article Brad, Looking forward to implementing this on my M100. Thanks for contributing to the group.

Earlier (on the facebook group) I'd mentioned that I fabricated a contrast replacement pot for the NEC PC-8201. It seemed that it wouldn't work on my Model 100, so I had to go back to the digital drawing board. And now the design works for both, the 8201 and the m100. No idea about the Olivetti M10 or the Kyotronic 85 -- don't have examples of those on hand to test :) I've posted more images and details about the kit here:http://stuff.bradgrier.com/docs/things/drop-in-vr1-replacement-contrast-potentientometer-forr-radio-shack-trs-80-model-100-and-nec-pc-8201a/ ... but happy to discuss here as well :) -- -- Brad Grier
