OK, I'm going to go with 2 chips for now. I'll order later if I actualy have time to build the EIIs. I may ask for 4, but that all depends on whether some peaople want them or not. I'll contact you soon. -- Richard Piotter richfile@prairie.lakes.com The Richfiles TI Hardware and BASIC web page: http://www.geocities.com/SiliconValley/Lakes/5081/Richfiles.html
