Please! keep me informed of al the steps in accomplishing this 'great wall' project! I would thank it you very much. Also, I promise spending long time studying your designs, especially trying to emulate EEPROM memory wit 555's. If you get the point of removing power and saving contents, for sure I will buy your design. Maybe you could come also with some simulation tools for your design (I suggest you using a PIC to emulate). I could help in writing the software Windows NT tools. Will your design be also programmed in circuit? Via a Serial, parallel port or maybe any special device? Thanks for the good time, Andres. -----Mensaje original----- De: N STEENKAMP [M.ING E&E] Para: PICLIST@MITVMA.MIT.EDU Fecha: miircoles 10 de junio de 1998 21:18 Asunto: Re: building a PIC emulator from 555s >Hi, > >> I would like any help I can get building a emulator for a PIC16C84.
