RE: HP Overlays Question
Lexan (polycarbonate). You can see any number of companies that make lexan overlays with a web search:
https://duckduckgo.com/?t=canonical&q=le...lay&ia=web Our company made a product from 1995-2008 or so that used a lexan overlay because it allowed annunciators to be to be totally invisible until lights came on behind them, and then they'd pop out of the black background. http://WilsonMinesCo.com (Lots of HP-41 links at the bottom of the links page, http://wilsonminesco.com/links.html ) |
