Hi, I'm building a vectrex lightpen and have all the parts except the phototransistor http://www.playvectrex.com/vectech/mvlp/mvlp_f.htm(parts list) Anyway I can't find the one on the list but if anyone knows of a similar one that will work on the circuit using these specs http://www.newark.com/jsp/search/productdetail.jsp?SKU=84F234&CMP=AFC-GB100000001 If anyone does know it would be greatly appreciated
