For removing Novell from EPROM chips, you either just overwrite it (if it is an EE-PROM, meaning eletrically erasable) or you have to UV-erase it - that is for the chips with a small window on top, meaning to put them under an unshielded face tanner or a dedicated eprom-eraser for a night, for example (which is what we did - neighbours wondered about that bluish light in the garage windows, but they learned not to ask questions on geekish behaviour anyway). For writing, quite simple devices often are sufficient. We built the batronix.com circuit http://batronix.com/elektronik/bauanleitungen/eeprommer-gif.shtml which seems to be a bit less sophisticated than what you plan to build, but does support the 27C512 and 27C... whatever. We ordered the complete self-building kit - as it's a german enterprise, that was not too expensive in shipping for us ;-> Hth Anselm ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _____________________________________________________________________ Ltsp-discuss mailing list.
