The LED strip came from Jameco, see picture. It just fits under the cover. I used self stick Velcro to attach it, so if you do not like it is easy to remove. I like it. I used to work with a Veenstra here in Wisconsin. Mike Zahorik (414) 254-6768

Subject: [GreenKeys] Lamp for ASR33 A couple of weeks ago I asked about a lamp that illuminates the typing on a ASR33 TTY. Apparently there was no such thing. So, I found a LED strip that I Velcro'ed to the underside of the cover. I connected the LED's to the 48 volt supply through a full wave bridge, filter cap and a dropping resistor. This LED has 36 LED's and is rated at 200 ma, but that is way way too bright. I cut it down to 70 ma and this is plenty bright. These pictures are not the best, but I'm pleased with the results. It is now easy to see what is being typed. Mike Zahorik (414) 254-6768
