Are you trying to find discrete equivalents of what goes into a modern chip= , or is it OK to use technology appropriate to the era when transistors were actually used to build computers? In the latter case, a "proper" transistorized computer would have used ferr= ite core memory for rewritable nonvolatile storage, and either a diode matrix o= r "rope memory" (like the Apollo spacecraft computers) for one-time programma= ble memory. -- Dave Tweed --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
